  1. Building Requirements for Roof Davit Systems

    Leave a Comment

    Whether inspecting HVAC systems, cleaning windows, or repairing facades, roof davit systems offer a stable structure to perform activities effectively. They ensure safe and efficient access to rooftops for repair work and maintenance. These versatile mechanisms provide a secure anchoring point for suspended platforms, allowing workers to carry out tasks at various heights.

    Since these structures are often permanently mounted on rooftops, it is critical to understand their building requirements to ensure they can withstand environmental factors. This article will discuss the fundamentals of davit systems and relevant regulations and codes.

    What Are Roof Davit Systems?

    Roof davit systems consist of arms, bases, and winches to handle different platforms, bosun chairs, or boats, enabling workers to reach elevated, hard to reach areas safely. The arms are attached to the building’s structural deck, providing a stable and reliable support mechanism. The bases serve as strong foundations and are securely fastened with mounting plates, while the winches allow for controlled lifting and lowering.

    Unlike traditional access methods that require constant setup and dismantling, davit systems remain permanently installed. This feature leads to substantial time savings and streamlines the workflow for maintenance and repair tasks. Additionally, employees can use the equipment with minimal training, as the interfaces are designed for user-friendly operation.

    Key Building Codes and Facets of Davit Systems

    Building requirements are crucial to ensure access systems’ safety, compliance, and effective functionality. They are significant in providing secure rooftop passage for work, so adherence to regulations and best practices is essential. Here are several codes and facets to keep in mind:

    Regulatory Compliance

    Building owners and managers must ensure that the installation and operation of roof systems comply with relevant industry regulations and standards. For example, the Occupational Safety and Health Administration (OSHA) provides comprehensive fall protection and equipment guidelines. Local building codes also impose requirements regarding these systems’ design, installation, and maintenance.

    Structural Integrity and Load Capacity

    Davit systems should be installed on structurally sound rooftops capable of supporting the extra loads imposed by the system and workers. An engineering assessment of the rooftop’s structural capacity is necessary to determine the appropriate anchoring methods and load capacity.

    Material Selection and Durability

    Under outdoor exposure and varying weather conditions, roof davit systems should be constructed from high-quality, durable materials. The materials must also be capable of withstanding UV radiation, temperature fluctuations, and moisture exposure. Thus, stainless steel and other corrosion-resistant materials are commonly used to ensure the system’s longevity and reliability.

    Fall Protection Measures

    Fall arrest mechanisms provide an additional layer of safety, helping prevent serious injuries in a fall. So, equipment designers must incorporate robust measures to safeguard workers at elevated heights. Additionally, personal fall arrest systems including harnesses and lanyard should be utilized by workers while using the davit system.

    System Design and Configuration

    The design and configuration should be tailored to suit the specific needs of the building and the nature of maintenance and repair tasks. Customization may be necessary to accommodate rooftop obstacles or irregularities. Also, the system’s layout should allow for efficient movement of workers and equipment across the rooftop.

  2. Difference Between Roof Coating and a Liquid Membrane Roof

    Leave a Comment

    When protecting your commercial building, the roof is crucial in keeping the elements at bay. Fortunately, several roofing solutions are available, including roof coatings and liquid membrane roofing. Choosing the right option for your needs is essential, as it can significantly impact your roofing system’s durability, performance, and overall cost.

    This blog compares roof coatings and liquid membrane roofing to help you choose the right one for your needs.

    What Is a Roof Coating?

    A roof coating is a protective layer added to existing roofs. Its main purpose is to enhance a systems lifespan, energy efficiency, and resistance to leaks, weather, and UV damage. Roof coatings are typically made from acrylic, silicone, or elastomeric compounds and can be applied to various roofs, including metal, asphalt, and single-ply membranes.

    Pros and Cons of Roof Coating

    Roof coatings offer several advantages, including increased energy efficiency due to their reflective properties. This results in reduced cooling costs and protection against leaks and UV damage. Additionally, they can extend the life of an existing roof by providing an extra layer of defense against wear and tear.

    However, roof coatings may not suit all roof types or conditions. Their effectiveness depends on the climate, roof age, and coating material quality. Some roof coatings may also require regular maintenance, such as cleaning and reapplication.

    Types of Roof Coatings

    Selecting the right roof coating is crucial for longevity and performance. Here’s a brief overview of popular industry choices:

    • Acrylic coatings are cost-effective, durable, and retain color well.
    • Due to their flexibility and high solids content, silicone coatings resist UV radiation and weathering, making them suitable for fluctuating climates.
    • Polyurethane coatings, with high tensile strength and impact resistance, are ideal for roofs with regular foot traffic or mechanical stress.
    • Asphalt coatings offer robust waterproofing with excellent adhesion and durability, making them versatile for different substrates.
    • Elastomeric coatings can withstand expansion and contraction without damage, mitigating thermal cycling effects. They are also resistant to weathering and UV exposure.
    • Mineral coatings include mineral granules that reflect solar radiation, enhancing roof lifespan and thermal efficiency.

    What Is a Liquid Membrane Roofing?

    A liquid membrane roof is a seamless, waterproof system featuring a liquid material that cures into a resilient, elastomeric membrane. They are often used on flat or low-slope roofs and can be made from polyurethane, rubber, or modified bitumen.

    Pros and Cons of Liquid Membrane Roofing

    Liquid membrane roofs provide a seamless, watertight barrier that effectively prevents leaks and withstands harsh weather conditions. They are highly durable and can offer a longer lifespan than some traditional roofing materials. Liquid membranes can also come in handy at areas on a roof with little to no flashing height, as well as for flashing atypical, oddly-shaped penetrations that cannot be flashed traditionally with a membrane sheet.  Additionally, liquid membrane roofs can be applied over existing roofing systems, reducing the need for costly tear-offs and disposal.

    Since liquid membrane roofing tends to be more complex to apply, it requires professional installation and specialized equipment. Many liquid membranes require mixing and/or catalysts prior to use, so it is vital that the instructions are read and followed precisely. Weather is a factor too, as many liquid membranes have strict minimum temperature requirements for installation, so following the manufacturer directions is vital. In addition, it can be more expensive than traditional roofing methods or roof coatings due to the cost of the material itself, and the time and care it takes to install them properly.

    Types of Liquid Membrane Roofing

    Liquid membrane roofing comes in various types:

    • Perfect for industrial settings, the Epoxy Liquid Membrane is resistant to chemicals and wear.
    • The Polymer-Modified Liquid Membrane can be applied to various substrates with its enhanced flexibility and superior waterproofing.
    • The Liquid Rubber Membrane is recognized for its exceptional elasticity and UV resistance, making it an environmentally friendly choice.
    • The Liquid PVC Membrane is a standout in weathering resistance and adaptability in extreme temperatures.
    • The Fiberglass Liquid Membrane, which incorporates fiberglass for added strength and longevity, effectively manages thermal cycling effects.

    Roof Coating vs. Liquid Membrane Roofing

    Liquid membrane roofing generally outperforms roof coating in durability and lifespan. However, it’s important to note that the longevity of any roofing solution depends on proper installation and regular maintenance.

    A professional roofing company can ensure that you get your money worth from a roof coating or liquid membrane roofing. A reputable contractor with a strong track record and industry credentials ensures the correct application of the chosen solution, optimizing roof performance and longevity.

    Leave a Comment

    Proper roof maintenance is a critical aspect of facility management for businesses. It ensures a commercial property’s safety, comfort, and longevity. It also provides significant financial benefits, as a sound roofing system protects against property damage that can lead to consequential losses.

    This blog examines the crucial aspects of maintaining commercial building roofs, covering topics like diverse roofing materials and regular maintenance procedures. We’ll also emphasize the value of partnering with expert contractors and recognizing when it’s time for a roof replacement.

    Materials and Requirements for Commercial Roofing Maintenance

    Neglecting roof care can lead to numerous issues, such as leaks, water damage, mold growth, and greater structural damage. Regular maintenance helps prevent these problems and ensures that your commercial roof remains in optimal condition. By addressing minor issues early on, you can prevent expensive repairs or untimely roof replacements.

    There are several types of roofing materials available for commercial buildings, each with its unique maintenance requirements:

    Built-Up Roofing (BUR)

    BUR systems have multiple layers of asphalt and reinforcing fabrics. They require regular inspections for signs of damage, such as cracks, blisters, or punctures. Their drainage systems also need to be checked to ensure they function properly. This prevents water buildup that can lead to roof damage.

    Metal Roofing

    Metal roofs are known for their durability and low maintenance requirements. However, they still need occasional inspections for signs of damage, such as loose or damaged panels and rust or corrosion. Keep the roof clear of debris and trim overhanging branches to avoid scratches or dents.

    Single-Ply Membranes

    Common single-ply membranes include TPO, PVC, and EPDM. These roofing systems require frequent inspections for tears, punctures, or seam separations. Ensure the membrane is appropriately adhered to and that the flashing is intact to prevent leaks.

    Key Factors for Routine Commercial Roof Maintenance

    When conducting roof maintenance for commercial buildings, consider the following tips:

    Inspect for Leaks

    Regularly inspect your building’s interior for signs of water damage or leaks. Address any issues promptly to prevent further damage.

    Drainage System Maintenance

    Clogged drains can lead to water buildup and damage your roof. So, clean your roof drains regularly, especially after significant storms or heavy debris accumulation.

    Remove Debris

    Keep your roof clear of leaves, branches, and other debris that can trap moisture and cause damage. Trim overhanging branches to prevent them from falling onto your roof during storms.

    When To Replace Your Commercial Roof

    Eventually, every commercial roof reaches the end of its service life and requires replacement. Factors that may indicate it’s time for a new roof include the following:

    • Age: The lifespan of a commercial roof varies depending on the material used. For example, BUR systems typically last 20-30 years, while metal roofs can last 40-70 years. Consider a replacement if your roof is approaching or has surpassed its expected lifespan.
    • Persistent leaks: If your facility experiences frequent leaks or extensive water damage, replacing your roof may be more cost-effective than paying for constant repairs.
    • Extensive damage: If more than 30% of your roof is damaged, replacing the entire roof is often more economical than repairing individual areas.

    Remember: while some roof care tasks can be performed in-house, it is best to work with professional roofing contractors for regular inspections and more complex repairs. When selecting a contractor, look for licensed and insured professionals with a solid reputation in your industry. Then, schedule annual inspections and address any issues promptly to maintain the health and functionality of your roof.

  7. TPO vs. EPDM

    Leave a Comment
    Click to ExpandTPO-vs.-EPDM

    When choosing a superior, energy-efficient solution for commercial roofing, most projects these days choose between thermoplastic polyolefin (TPO) and ethylene propylene diene monomer (EPDM). There are numerous similarities between these two types of single-ply roofing membranes. However, there are notable distinctions on which companies or businesses should base their decision.

    This article will discuss TPO vs. EPDM — their advantages, disadvantages, and the key considerations when choosing these roofing systems.

    TPO Roofing Characteristics

    One of the commercial roofing products with the quickest market growth is the single-ply TPO membrane. These roofing systems cover flat roofs with a single layer of synthetic materials and reinforcing scrim.

    Pros of TPO Roofing

    Some of the advantages of TPO single-ply membrane roofing systems include the following:

    • It is extremely resistant to ozone, UV radiation, and certain chemicals.
    • It is cost-efficient.
    • It reflects heat radiation more effectively than EPDM.
    • It resists mod development, dirt buildup, rips, collisions, and punctures.

    Cons of TPO Roofing

    It also has disadvantages, such as:

    • It needs extensive maintenance repairs using specialized instruments, such as a heat welder, which may be pricey.
    • It becomes slick when wet, iced, snowy, or icy.

    EPDM Roofing Characteristics

    A roofing system made from EPDM typically consists of large sheets of rubber membrane that are sealed together to create a waterproof and durable surface. Using this option for your project has several benefits and drawbacks, which are discussed in more depth below.

    Pros of EPDM Roofing

    EPDM has several advantages, including:

    • It has been a reliable roofing option for over 50 years and has a well-established track record.
    • It resists weathering and remains flexible even in extreme temperatures.
    • It is typically less expensive than TPO, which may make it a more appealing choice for cost-conscious buyers.

    Cons of EPDM Roofing

    EPDM has some other downsides as well, such as:

    • Since black is the most commonly used color of EPDM, it does not reflect sunlight and heat, which can result in higher energy costs.
      • While white EPDM does exist, it is much more rare and it therefore much more expensive
    • It is more susceptible to punctures and tears than TPO, which may require more frequent repairs.
    • It is heavy and requires more labor-intensive installation than TPO sheets.

    Considerations for TPO vs. EPDM

    Evaluating your demands and interests while picking between TPO and EPDM is critical. When choosing between the two, there are several important considerations to keep in mind:

    Energy Efficiency

    TPO is a great choice if energy efficiency is a top concern. Its light color reflects sunlight and heat away from the building, reducing energy consumption and cutting down on electricity costs. In contrast, EPDM’s dark color can absorb heat, raising the temperature inside the building and potentially increasing cooling costs.

    Puncture Resistance

    If the roof will be exposed to heavy foot traffic or other potential sources of damage, TPO is the way to go. It is more durable and resistant to punctures, rips, and other forms of disfigurement than EPDM. Therefore, it can last longer and require fewer repairs.

    Installation Convenience

    Both options can be installed easily and quickly for those who want to save on installation costs. Both TPO and EPDM can be installed in large, single-ply sheets that are mechanically fastened (TPO), adhered (both), heat welded (TPO), or ballasted (EPDM) which can save time and reduce labor costs.

    Dimensional Stability

    When it comes to maintaining the appearance and functionality of the roof over time, TPO is the more durable option. It is less prone to shrinking and expanding than EPDM. Therefore, it can better withstand temperature fluctuations and prevent cracks, gaps, and other damage over time.

    Seam Strength

    EPDM is the better choice for those who prioritize minimizing the risk of leaks. Its strong seams are usually formed with an adhesive or tape, which creates a watertight seal. However, TPO is often heat welded, which can create a stronger connection than glue or tape. If not done properly, it can lead to weaker seams than EPDM.

    Knickerbocker: Your Reliable Experts in Roofing Solutions!

    Overall, TPO may be a preferable alternative if energy efficiency, puncture resistance, and dimensional stability are essential considerations. On the other hand, if seam strength and a track record are the priority, EPDM may be the best choice.

    At Knickerbocker Roofing & Paving Co., we leverage our vast experience and knowledge in the roofing industry to provide you with the best possible roofing solution. Whether you need a TPO or EPDM roof, our team of experts will work closely with you to ensure your satisfaction!

    Leave a Comment
    Click to ExpandEPDM-Roofing-Benefits

    There are various roofing options for installation on commercial buildings and infrastructures. Nowadays, one of the most widely used types is ethylene propylene diene monomer (EPDM) roofing. It is an exceptionally durable rubber roofing membrane utilized in low-slope applications, protecting commercial structures effectively.

    EPDM has several advantages over different types, as with any other roofing material. This article will discuss the benefits of EPDM roofing so that you can determine if it is the best option for your commercial building.

    What Is EPDM Roofing?

    Also referred to as rubber roofing or rubber membrane roofing, EPDM roofing utilizes two main ingredients, ethylene and propylene, which come from both oil and natural gas. It is available in black and white and in widths ranging from 7.5 to 50 ft., lengths up to 200 ft., and thicknesses up to 90 mm.

    Typically, EPDM roofing is used on flat roofs or other low-slope installations. Common installation methods include fully adhered with adhesive, ballasted with river rock, or mechanically fastened to the deck with plates and fasteners.

    What Are the Advantages of EPDM Roofing?

    EPDM roofing is one of the most popular flat roof systems because of its great longevity and economical material. Here are some of its benefits that make it a go-to roofing material:

    Durability

    Durability is one of the main advantages of EPDM roofing. While most roofing materials require replacement every 10 to 20 years, EPDM roofing can last up to 50 years with proper inspection and maintenance.

    Rubber is not easily scratched and may withstand mild fire exposure. Moreover, rubber roofs are resilient throughout the winter and summer and are less prone to crack or break under adverse weather conditions.

    Affordability

    EPDM is one of the least expensive materials on the market, making it a cost-effective roofing option. Its flexibility and malleability make it easier to install than other single ply membranes such as TPO and PVC. Additionally, EPDM roofing’s maintenance and replacement costs are not burdensome. You can also save money on energy expenditures, as it is beneficial in both summer and winter.

    Ease of Maintenance and Repair

    Compared to other roofing materials, EPDM roofs require minimal maintenance. This is because the waterproof membranes are securely flexible and have the same lifespan as the base material.

    Although it may need inspection sometimes, it is simple to handle any difficulties that may arise because rubber repairs are simple and quick. Still, scheduling regular maintenance is highly recommended to ensure everything works properly throughout the year.

    Resiliency

    EPDM roofing is particularly resilient due to its rubber membrane composition. It is flexible enough to curve around gutters, pipes, and rafters and resistant to extreme weather. In addition, it can endure temperatures between -58 ℉ and 300 ℉.

    Energy Efficiency

    White EPDM roofing is known for its high level of energy efficiency, as the white color of the material is highly reflective and helps to reduce the amount of heat absorbed by the building. When sunlight hits a white surface, the majority of the sun’s energy is reflected back into the atmosphere rather than being absorbed, which helps to keep the building cooler.

    EPDM also allows additional coatings to strengthen its durability and reflectivity, resulting in greater energy efficiency.

    Eco-Friendliness

    The materials used to produce EPDM roofs are 100% recyclable, and very little waste is sent to landfills when a membrane is removed from a roof. They can also be recycled when they reach the end of their lifespan. In addition, they are compatible with rooftop gardens, resulting in increased air quality and a cooler interior.

    Green roofing is nothing new—the concept goes back centuries, and Germany started constructing modern green roofing systems in the 1960s—but it’s finally catching on in a more mainstream way. More and more companies and organizations are realizing the massive benefits that a green roof offers to not only their buildings, but the community at large.

    Green Roofing Best Practices/Considerations

    A green roof installation can improve the aesthetics of your building while providing insulation, energy savings, rainwater management, and an extended lifespan for your roof. Every building is different, so they all require a customized approach and careful cost-benefit analysis.

    When you decide to add a green roof to your building, there are a few considerations you need to keep in mind:

    • Green Roof Type: Extensive roofs have a thin layer of soil requiring minimal irrigation. They’re lightweight, low maintenance, and often ideal for large spaces, but you’ll have a limited selection of plants. Intensive green roofs are heavier, with deeper soil that provides favorable conditions for many types of plants. These roofs require irrigation and more extensive maintenance, but they can often be used as a rooftop park. Semi-intensive roofs typically have both intensive and extensive features. Green roofs can be installed on flat and low-slope roofs.
    • Green Roof Layers: No matter what type of green roof you choose, it will be made up of several layers, including decking, vapor control, insulation, a waterproof membrane, root barrier, drainage layer, filter, soil/substrate, and plants.
    • Installation Method: Hiring professionals to install your green roof is essential to ensure it meets construction regulations—and to make sure your building isn’t damaged in the process.
    • Irrigation Systems: Choose from spray or drip irrigation systems; in some cases, drainage-layer irrigation may be an option.
    • Soil Type: Depending upon the type of green roof and kind of plants you’re using, you can choose from specially-designed substrates that may include mulch, sand, pumice, clay, peat moss, vermiculite, and soil.
    • Plants:Intensive roofs can support almost any type of plant life, except those with aggressive and deep root systems. Choices are more limited on extensive green roofs.
    • Structural Requirements: Your building must be able to support the weight of the green roof, which includes the weight of the layers as well as water and potentially people, if your green roof is meant to be an outdoor recreational space.

  11. What is Green Roofing?

    Leave a Comment
    Click to ExpandGreen Roofing

    Busy urban areas are starting to take advantage of a previously underutilized space: the roof. Instead of plain, dark roofs that contribute to the urban heat island effect, more and more buildings in Chicago and around the country are incorporating green roofing into their energy codes to reduce energy costs, create usable outdoor space for people to enjoy, add vegetation that helps purify the air, and absorb rainwater.

    What Is Green Roofing?

    A green roof is a layer of soil and vegetation planted over a waterproofing system installed on a flat roof. These roofs must be carefully designed with specific layers to support plant life and protect the building, including layers for structural support, waterproofing, drainage, and more.

    As an alternative to a traditional roof, green roofing serves a number of purposes. It helps insulate the building, which reduces the load on the HVAC system. Not only does that help the building save money on energy, it also prolongs the life of the heating and cooling system. During a storm, up to 90 percent of the water is used by the plants and returned to the atmosphere via evaporation, rather than running off the building and into the sewer system. As mentioned previously, green roofs also reduce the urban heat island effect and create a more beautiful city.

    How Green Roofing Works

    There are three loosely defined types of green roofing:

    • Intensive: These are rooftop parks or gardens that can support up to 150 pounds of vegetation per square foot. They often include walkways, benches, trees, and more, and require a complex system for support, irrigation, and root protection.
    • Extensive: These are simpler, lighter installations supporting up to 50 pounds of vegetation per square foot. These aren’t designed to be used by the public, and instead function as an aesthetically pleasing, environmentally beneficial space. They can be installed on a slightly sloped roof and require little maintenance.
    • Semi-Intensive: This in-between type of green roof may feature both extensive and intensive elements. Chicago’s own City Hall, one of the better-known green roofs, could be considered semi-intensive.

    All three types offer many of the same benefits, including improved air quality, building insulation, and more.

    Benefits of Green Roofing

    The extensive benefits of green roofing have been enjoyed in Europe for years, and slowly the United States is catching up to the realization that installing a green roof is an investment that pays off in many ways.

    • Sustainability: Improved building insulation reduces the load on the HVAC system, which prolongs its life, saves replacement costs, and keeps roofing debris out of the landfill. Green roofs are often built with recycled materials, and they reduce stormwater runoff.
    • Reduced Energy Costs: The vegetation on a green roof absorbs heat and cold, which enhances the effectiveness of the insulation installed, which in turn can reduce your energy costs.
    • Aesthetics: Vibrant green roofs are more interesting and attractive than traditional roofing, and they contribute to the beautification of a city.
    • Reduced Maintenance: Even though plants and vegetation require regular maintenance, the roof membrane is protected by the plants, which helps it last longer and reduces your roof maintenance costs.
    • Stormwater Management: A green roof can absorb up to 90 percent of rainwater in the summer and up to 40 percent in the winter, reducing the strain on the sewer system.
    • Waste Diversion: Longer-lasting roof membranes and HVAC systems reduce the waste that ends up in landfills.
    • Improved Air Quality: Plants help moderate the temperature and filter dust and noxious gases.
    • Fire Retardation: Certain species of plants are drought resistant and hold on to water for a longer period of time, making them less prone to catch fire.  Also, the irrigation systems many green roofs require can aid in the prevention of a roof fire spreading
    • Noise Reduction: An intensive green roof can reduce outside noise by up to 50 decibels.

  12. Liquid Roof Coatings vs. Liquid Membrane Coatings

    Leave a Comment

    Knickerbocker Roofing & Paving Co., Inc. is a premier provider of industrial, commercial, and institutional roofing solutions. Equipped with over 130 years of industry experience, highly skilled employees, and a wide range of roofing materials, we have the knowledge, skills, and resources needed to accommodate all of our customer’s roofing needs. One of our core service offerings is liquid membrane roofing.

    The terms “liquid roof coating” and “liquid membrane roofing” are sometimes used interchangeably. However, while there a few similarities between the two, they are distinct roofing products. The following blog post provides an overview of liquid roof coatings and liquid membrane roofing and discusses the key differences between them.

    Liquid Roof Coatings vs. Liquid Membrane CoatingsOverview of Liquid Roof Coatings

    Liquid roof coatings are elastomeric materials designed to be sprayed on to roofing surfaces to form a protective layer against environmental conditions (e.g., dirt, debris, or water). The materials have a consistency thicker than paint, which allows them to produce a thick film that effectively seals gaps and cracks in and between flashings, gutters, tiles, and other roofing elements. When applied correctly, they offer a number of benefits, including:

    • Lowered energy costs. Many roofing coatings offer emissive or reflective properties, which reduce the roof temperature and the strain on the building’s heating and cooling systems. As a result, they help lower energy utilization and, consequently, energy costs.
    • Extended roof life. Roofing coatings help extend roof life by forming a barrier between the roof and the environment. This barrier protects the roof surface from damage and degradation caused by rain, snow, heat, UV radiation, and other environmental conditions and foot traffic from repair and maintenance work.
    • Reduced construction debris. By extending roof life, roofing coatings reduce the need for maintenance and repair work. As a result, less construction debris is created throughout the working life of the roof.

    Overview of Liquid Membrane Roofing

    Liquid membrane roofing is a roofing system that consists of liquid coatings applied over reinforcement material and the roofing base material. This multi-layer system forms a seamless barrier that fills in all cracks, gaps, and voids to protect the roof from damage and degradation caused by water intrusion, impact damage, stress cracking, and ultraviolet radiation. Compared to other roofing systems, it offers the following benefits:

    • Broader versatility. Liquid membrane roofing systems are suitable for a variety of roofs as the liquid coating adheres to and cures on most roofing materials. They can also provide waterproofing and weatherproofing to exposed roofs with many protruding or penetrating elements and/or damaged and uneven surfaces.
    • Greater durability. Liquid membrane roofing systems form a tough and flexible protective barrier that is extremely resistant to damage and degradation from normal and extreme environmental conditions.
    • Easier and safer installation. Unlike some roofing systems that require heat to spread the roofing material (e.g., bitumen roofing systems), liquid membrane roofing systems are applied and cured cold. As a result, they are much easier and safer to install.
    • Better cost-effectiveness. By protecting roofs from damage, liquid membrane roofing systems help extend roof life and reduce maintenance, repair, and replacement costs.

    Liquid Roof Coatings vs. Liquid Roofing Membranes

    Both liquid roof coatings and liquid roofing membranes consist of polymer-rich materials that form waterproofing and weatherproof barriers atop the roof surface. Beyond these similarities, the two roofing products differ with regard to several key aspects.

    • Liquid roofing membranes serve as a long-term protective barrier for roofs, while liquid roof coatings are generally used as a short-term secondary protective layer that somewhat extends the life of the membrane system and/or roofing surface.
    • Liquid roof coatings can fill smaller gaps and cracks but aren’t as effective as liquid membrane systems for more damaged roofs or those subject to more extreme conditions.
    • Liquid membrane solutions generally cost more than liquid roof coatings but return that investment in longevity and durability. However, they may not be suitable for all roofs, depending on the age of the roofing material and the budgetary limits of the project.

  13. Types of Single-Ply Roofing Systems

    Leave a Comment

    Types of Single-Ply Roofing SystemsAll roofs feature some slope to allow for drainage. Low-slope—sometimes referred to as “flat”—roofs generally feature a very slight slope of less than 3:12. Slopes are represented as a ratio of how much the roof rises (vertical) over the distance (horizontal) between its lowest edge and its highest edge. A 3:12 slope indicates a rise of 3 inches over a 12-inch distance.

    There are a number of different low-slope roof systems, including:

    • Built-up Roof (BUR) Membrane Systems. Built in several layers, including insulation board, perlite, inter-ply sheets, asphalt, and pea gravel ballast repeated in various combinations
    • Polymer-Modified Bitumen Sheet Membrane Systems. Built with reinforced bitumen membrane fabrics that are either mopped on using hot asphalt, heat welded, or torch applied
    • Spray Polyurethane Foam-Based (SPF) Systems. Built by spraying foam consisting of heated and properly proportioned isocyanate and polyol
    • Single-Ply Membrane Systems. Built by applying a single layer over a roof structure or insulation board

    The following blog post discusses each of the three types of single-ply roofing systems, outlining their characteristics, applications, and advantages and disadvantages.

    Types of Single-Ply Roofing Systems

    Single-ply roofing systems utilize flexible sheets of thermoset or thermoplastic membranes. Both membranes offer unique advantages and disadvantages. For example, thermoplastics are highly reusable as they can undergo melting numerous times, while thermosets remain in a solid state after curing. The three main types of compounds used in single-ply membrane systems are:

    • Ethylene propylene diene terpolymer (EPDM): a thermoset
    • Polyvinyl chloride or polymerized vinyl chloride (PVC): a thermoplastic
    • Thermoplastic polyolefin (TPO): a thermoplastic

    EPDM Roofing

    Composed of two main ingredients—i.e., ethylene and propylene (derived from oil and natural gas)—EPDM is a synthetic rubber. EPDM roofing membranes come as large, black or white rolls with widths ranging between 7.5–50 feet (10 feet being the most common) and thicknesses of 45, 60, or 90 mils. Roof systems which use this material typically have life spans ranging between 10 and 25 years.

    Common installation methods include full adhesion, mechanical attachment, or ballasting followed by gluing or taping of the seams. As the EPDM material is available in large rolls, it is an ideal roofing solution for large commercial buildings, such as warehouses, office buildings, hotels, shopping centers, large retail stores, schools, and universities.

    Advantages of EPDM roofing systems include:

    • Resistance to hail and abrasion
    • Durability under extreme weather conditions
    • Flexibility in cold weather climates
    • UV radiation resistance
    • Flexible membrane allows for easier installation, especially at flashings and penetrations
    • Cost-effectiveness

    Disadvantages of EPDM roofing systems include:

    • It tends to absorb more heat, leading to a higher risk of structural overheating in extreme heat.
    • It punctures easily, so walking on it should be limited or avoided.
    • It shrinks in dry, hot climates.

    PVC Roofing

    PVC is a synthetic, thermoplastic polymer composed of polyvinyl chloride. It exhibits several advantageous material properties, including resistance to wind, moisture, fire, and chemicals. PVC roofing material usually comes in rolls of 50–100 feet long and 5–12 feet wide. It is installed using full adhesion, mechanical fastening, or ballasting and seam welding methods.

    The lifespan of a PVC roof system installation ranges between 15 and 30 years. As the roofing material is packaged in smaller rolls than EPDM roofing systems, it is easier to install. This quality also makes this roofing system suitable for smaller commercial and residential installations.

    Advantages of PVC roofing systems include:

    • High strength (up to 350 pounds per square inch breaking strength)
    • Durability due to welding of seams rather than using tapes or liquid adhesives
    • Superior resistance to moisture, wind, fire, and chemicals
    • Versatility (can be used for patios, decks, and balconies with added non-slip coating)
    • Reflective surface

    Disadvantages of PVC roofing systems include:

    • Its material costs tend to be higher.
    • May lose reflectivity over time due to excessive air pollutionLess flexible membrane can make for a more laborious installation, especially at flashings and penetrations.

    TPO Membrane Roofing

    TPO membrane roofing systems are rapidly growing in popularity in the commercial roofing market. These systems feature a single layer of synthetic thermoplastic combined with reinforcing scrim that provides a naturally reflective surface that resists UV radiation penetration and wear. The roofing material is available in rolls with widths of 10, 12, or 20 feet and installed using mechanical or adhesive attachment with heat-welded seams.

    A TPO membrane roofing system’s life span ranges from between 7–20 years. As TPO roofing material has similar roll sizes to EPDM roofing systems, their applications overlap.

    Advantages of TPO roofing systems include:

    • Reflective surface (suitable for preventing UV radiation wear or exposure)
    • High strength (3–4 times stronger than EPDM, but not quite equal to PVC)
    • Durability (due to welded seams)
    • Excellent wind resistance​​
    • Low cost material

    Disadvantages of TPO roofing systems include:

    • Like PVC, a less flexible membrane can make for a more laborious installation, especially at flashings and around penetrations.It has a short life span.

  14. TPO vs. PVC Roofing

    Leave a Comment

    TPO vs. PVC RoofingThermoplastic polyolefin (TPO) and polyvinyl chloride (PVC) are two types of single-ply membranes utilized in low-slope and flat roofing systems. The two thermoplastic materials demonstrate similar physical characteristics—e.g., high strength, durability, and wind resistance. Despite these general similarities, when designing a roofing system, it’s important to consider the distinctive advantages and disadvantages of using each material so that you can make the best choice for your project specifications and budget.

    The following blog post provides an overview of TPO and PVC roofing, discussing each material’s characteristics, pros, and cons and outlining general selection considerations.

    TPO vs. PVC Roofing

    As TPO and PVC are both thermoplastics, the two materials have some overlapping characteristics. However, there are distinct differences in their composition and more particular properties.

    Overview of TPO Roofing and PVC Roofing

    TPO roofing membranes consist of an ethylene or polyethylene thermoplastic bound to ethylene propylene rubber. PVC roofing membranes are made by polymerizing vinyl chloride monomers, then adding plasticizers to increase flexibility.

    Although TPO was originally designed to be a superior alternative to PVC, it’s difficult to definitively say which is the optimal roofing solution. Both membrane materials offer—among other advantageous material characteristics—resistance to chemicals, grease, oils, and punctures to varying degrees. Deciding which of the two materials best suits a particular roofing application requires a more detailed look at their properties.

    Pros and Cons of TPO

    While PVC offers better resistance to puncture and weathering, TPO (like PVC) is recyclable and environmentally friendly.  Its reflective surface reduces UV radiation and helps with energy efficiency.However, TPO is also less resistant to chemicals than PVC, so it is not the optimal choice where grease or harsh chemicals are involved. It may also be more difficult to install due to its stiffness. Additionally, as the popularity of the material is relatively new, some manufacturers may use subpar formulations that demonstrate a higher risk of membrane cracking.

    Pros and Cons of PVC

    PVC has been a mainstay in construction for over 30 years, and its reputation for durability is well-deserved. PVC is highly resistant to chemical damage and somewhat resistant to punctures or weathering. It also tends to be more flexible and easier to install due to the addition of plasticizers in its formulation.

    However, the use of plasticizers does raise some concerns regarding weathering. Some plasticizers used in PVC break down more quickly than the rest of the material, increasing the rate of degradation. Additionally, the high durability of the material also results in generally higher material costs and environmental impact.

    Considerations When Choosing TPO or PVC Roofing

    The similarities between PVC and TPO make either material a likely option for most flat roofing projects. When deciding between the two materials, there are a few considerations that can help determine which is best suited for the project, such as:

    Cost

    TPO is cheaper than PVC per square foot of material. However, the amount of labor during installation is about equal for both materials, if not slightly more intensive for TPO.

    Labor

    PVC can be easier to install due to its greater flexibility. Additionally, some TPO installations may require more work if the contractor decides to use glued seams over welded seams.

    Industry standards

    Due to the relatively regular updates to ASTM standards for TPO, some manufacturers may not follow the most recent standards. The same risk is much lower for established materials, such as PVC. When using TPO in roofing systems, it’s essential to pick a reputable supplier.

    Membrane quality

    Regardless of whether the roofing project uses TPO or PVC, it’s important to vet and choose an experienced Some of the things to look for in a supplier are extensive industry experience, consistently high-quality and industry-compliant products, and a clear warranty policy.

    Energy efficiency

    TPO and PVC roofing membranes both provide naturally reflective surfaces that reduce UV radiation penetration and facilitate greater energy efficiency. By using smoother TPO and PVC membranes, the roofing system is also better protected from dirt and debris buildup, which can reduce the membrane’s reflective properties. All major manufacturers of TPO and PVC membranes comply to the most stringent of energy codes, including in Chicago.

    Durability/Longevity

    In theory, TPO roofs should be more durable because they lack plasticizers. However, many PVC roofs have withstood decades of wear without failure, so it’s less of a concern than some make it out to be.

    Quality TPO and PVC Roofing Solutions From Knickerbocker

    PVC and TPO are both suitable for use in industrial, commercial, or institutional roofing projects. However, when choosing between the two, it’s essential to understand the unique advantages and disadvantages of each material. Additionally, once you’ve made the decision, you should source from an experienced and reputable  manufacturer to ensure you receive a high-quality product.

    At Knickerbocker Roofing and Paving, we provide PVC and TPO roofing system installations,   including green roof designs.

  15. A Guide to Selecting the Right Low Slope Roofing Materials

    Leave a Comment

    Roof systems generally fall under two distinct categories —low slope and steep slope. Low slope roofs—sometimes referred to as flat—range from 0 inches per foot up to 4 inches in a foot of run. Low slope roof systems must provide the following:

    • Weatherproofing
    • Sturdiness
    • Reinforcement
    • Surface

    Weatherproofing is especially critical in low slope assemblies because they drain water much slower than steep slopes. This means that low slope roofs don’t require mechanical drainage solutions like asphalt shingles or slate.

    Low slope and steep slope systems require different material types and components to function successfully. As such, many roofing material suppliers arrange their materials into low slope and steep slope categories. This guide will help readers select an appropriate solution for their low slope roofing project.

    Low Slope Roofing Material Selection

    When it comes to choosing the appropriate material for a low slope roofing project, you’ll want to consider the following:

    1. Warranty. Each manufacturer of low slope roofing products will have their own unique warranty offering. Many of these specify that the low slope roof is kept to a minimum of 0.125”/foot or 0.5”/foot slope for the warranty to remain valid.
    2.  Slope. Almost all roofing materials specify a slope range for which they are best suited. It’s essential to work with a manufacturer that understands roofing material and system nuances.
    3. Membrane. Choosing membrane materials is essential for low slope roofs. Since water drains slower, the selected materials must be able to tolerate exposure to pooled water.
    4. Temperatures. Freezing and thawing of pooled water will always be a primary concern for low slope roofs in colder environments, as this can damage almost any roofing structure. Not only can pooled water increase the deflection in roof framing due to weight, but it can contribute to the growth of moss, algae, or other harmful organisms that will decrease the lifespan of the roofing system.

    Most low slope roofing systems on the market utilize three main material options:

    1. Built-up roof (BUR) membranes
    2. Modified Bitumen
    3. Single-ply membrane

    Low Slope Roof Material Offerings from Knickerbocker

    Low Slope Roof Material Offerings from Knickerbocker

    This recent project demonstrates Knickerbocker’s low slope roofing system capabilities. We were asked to manage a commercial roofing project that included the removal of an old low slope roof and the installation of a new roofing system.

    Knickerbocker has been in the roofing business for more than 130 years and we’ve worked on every type of roof imaginable. On that note, this project was of particular interest to us because we were responsible for installing the roof that was currently on the building—all the way back in 1948, and then again in the early 1980s Roofing technology has evolved significantly in recent decades, and this particular roof needed to be upgraded with a more advanced solution.

    Here are the steps that we took to remove and upgrade this commercial low slope roofing system.

    1. We removed the roof that we had previously built by disassembling the roof and hoisting the debris down a freight elevator at night (to reduce customer impact).
    2. During the day, we installed the new roofing system using our multi-ply modified bitumen system—which features additional waterproofing capabilities along with dimensional stability and puncture-proofing.
    3. We also used Dow insulation and Wausau roof pavers during the process for both function and aesthetics. Insulation helps the building manage interior temperatures and saves the customer money on energy costs.
    4. Due to the age of the roof’s drainage system, we retrofitted the entire drainage system using newer materials.

    During this project, we used:

    • Multi-ply Modified Bitumen
    • Dow insulation
    • Wausau roof pavers

    This is one of many low slope commercial roofing projects that we’ve completed over the years. We take a customized approach to each project, ensuring that we use construction methods and materials that will provide the longest lasting solution for the particular building design.

    Low Slope Roofing from Knickerbocker Roofing

    Constructing an effective, long-term low slope roofing system requires a keen eye for detail and an understanding of roofing material options and how they will be impacted by the building design and environmental factors. Some materials are ideal for certain situations, while others may hinder the project or introduce unnecessary risk factors. Choosing Knickerbocker for your roofing project ensures the use of the most appropriate materials and methods for the job.

  18. 3 Tips to Keep Your Commercial Roof in Shape this Winter

    Leave a Comment

    With the winter season closing in on the construction and roofing industries, commercial businesses should prepare to take a look at their current roofing systems’ longevity. Harsh weather conditions like the sleet, intense cold, and freezing drafts are here to expose all of your weaknesses. Instead of playing the waiting game take initiative on your roof and prevent situations that can lead to roof and ceiling leaks or obstructed damage to drain systems. Your deterioration is beyond a simple inconvenience.

    Here are a few forward-thinking tips to ensure your commercial roof is in tip-top shape throughout the menace of winter.

    Action is better than reaction:

    Going through roof construction in the chaos of winter’s worst elements leads to one big headache. Bottom line, your business (building and employees included) will respond better to pre-emptive measures before the cold strikes. So what can you do?

    1. Book an inspection. Certified professionals go over every square inch of the roof and check for known deficiencies that may be exacerbated by the forces of winter. Common problems that are identified include possible leaks, poor joint integrity, sheet metal flashing degradation, random punctures and unsealed pitch pans.
    2. Budget ahead of time. A report, complete with images and a prioritization of the proposed repairs, is compiled based on the findings of this inspection. This allows you to tackle the areas that can quickly escalate into an emergency. Use your available funds for current and necessary improvements and make sure to allocate your budget for future modifications or complete reconstruction.
    3. Always upkeep. Thorough roof upkeep typically includes cleaning of all drain components and tightening of bolts, disposal of small debris, repair of deficiencies found on the flashing around roof penetrations and the field membrane and the inspection of all mechanical equipment on the roof. Special attention should be paid to the overall flexibility of the roof so that it can withstand contractions and expansions.

    Knickerbocker services:

    Knickerbocker Roofing offers inspection and commercial roof maintenance services. Our trained professionals know how to properly wield the tools of repair for your damaged roof. We are also certified with all major roofing manufacturers for contracting.

    If emergency services are required, we can accommodate.

    Please contact us today for your custom quotes.

    You can also follow us on Twitter & LinkedIn throughout the holiday season to stay on top of the latest in the commercial roofing industry.

    We wish all of you a very happy and healthy holiday season and look forward to reconnecting in 2018!

    3 Tips to Keep Your Commercial Roof in Shape this Winter

  19. Knickerbocker Roofing Recognizes National Manufacturing Day!

    Leave a Comment

    This Friday, October 6th, National Manufacturing Day (NMD) will highlight our industry, recognizing the hardworking businesses and employees that keep roofing and manufacturing at the forefront of the U.S. economy.

    For those companies and community organizations interested in joining this national effort you can register on the official site where your event can be marked as public or invitation-only.

    One of the annual objectives is to inspire the next generation of innovators for a continuous and thriving infrastructure. NMD puts a spotlight on the more than 2,000 American manufacturers who focus on the youth of our nation in an effort to mend the skills gap and help students pursue promising careers in science, technology, engineering, and math (STEM). Manufacturing and engineering are two of the biggest contenders for the spread of STEM education because all of those retained skills are then later and continuously applied throughout any given career path. Apprenticeships are one great option for interested students to pursue, as it gives participants the opportunity to flex, apply, and maintain relevant skills even further.

    At Knickerbocker Roofing we stand behind National Manufacturing Day initiatives as the next generation is the mantle of future American production and innovation. We also support other NMD efforts that include debunking manufacturing myths and reshoring business and career opportunities back to the U.S.

    With 130 years under our belt, Knickerbocker specializes in commercial, industrial, and institutional roofing services. As a leader in the roofing, sheet metal, and waterproofing industries, we find ourselves succeeding through the utmost in workmanship and service.

    We invite you to keep up-to-date with our offerings and services by following us on Twitter and LinkedIn. Stop by our website to receive contact information and enjoy our informational blogs.

    We thank those participating in the National Manufacturing Day efforts and ask you to continue to spread the word!

  20. What Roofing System Suits Your Needs?

    Leave a Comment

    There are five main types of steep roof systems: asphalt shingles, metal, slate, tile, and wood shake. The most common are asphalt shingles, which are found on many homes.   We would like to take a look at the other four today.

    Standing seam metal roofs are utilized on commercial, industrial and institutional structures as the entire roof structure.  They also provide eye-catching accents as part of a smaller roof on a larger structure.  A corrugated metal roof can provide a rustic feel to a structure.  Either way, these roofs need to have proper slope to shed the water and, if necessary, should have snow guards to protect from snow accumulations cascading down.

    Slate is rock that is split into smooth flat pieces for roofing.  There are several benefits of a slate roof, including its long lifespan of about 75 years, its fire resistance and that it is a natural resource.  The natural colors tend to blend in well with the surrounding environment, such as those on Lake Michigan. The cons can be the weight of the system and the initial cost which can be higher in comparison to other systems. You tend to see slate roofing systems on high-end residential, institutional, and ecclesiastical buildings where longevity is of the utmost importance.

    Clay tile roofing systems are commonly found in Southern climates, but provide a long-lasting natural solution anywhere in the U.S. An example of our clay tile installation can be seen at the Erman Biology Building at the University of Chicago. Tile options come in a variety of colors, have long term durability, are hail and fire resistant, and are built to withstand high winds. Based on their life cycle, they are more sustainable than other roofing systems. Maintenance and repair are similar in cost to slate, as is installation.

    Shake systems look wonderful in natural settings such as wooded and coastal areas and surrounding lakes. These systems do require more maintenance and have had general concerns in relation to fire hazards. While fire retardant systems are available, the chemicals used to defend the roof from fire can shorten the lifespan of the system. Still, with proper installation and maintenance, shake systems deliver as a beautiful system option.

    Depending on which commercial roofing system is right for you, Knickerbocker can install an optimal new roof for your building. Along with installations, Knickerbocker also works on emergency roof and leaking repair systems, provides low slope and steep slope roofing services, green roofing services, architectural sheet metal fabrication services, and roof maintenance services.

    Knickerbocker Roofing has been in business for over 130 years, specializing in commercial, industrial, and institutional roofing services.

    Knickerbocker Roofing installed approximately 88,0000 square feet of Carlisle Roof on the 111 North Canal buildingvc. Knickerbocker did exactly what they had proposed to do. The work was done neatly and on time. There was very little punch list by Carlisle.

    If our company had to do this over again, Knickerbocker would be the company picked to do the work.

    Our second important project, begun and completed this summer, was the replacement of the roof over the ballroom. This new roof-lighter, brighter, and with greater insulating properties – somehow was installed continuously UNDER all of the mechanical equipment already in place. We are grateful to Knickerbocker Roofing and Paving Co., Inc. for their expertise and patience in bringing this challenging project to completion. We look forward to many happy years enjoying what we do, in this room, under this new roof ….. The Knickebocker team did their usual fine job AND came in under budget.

    I would like to take the opportunity to commend you on the dispatch with which this job was completed. Working around the constraints imposed by Evans need to use the freight elevator almost all day long, and the need to keep the area clear and quiet for the Schubert Theater, was not easy.

    Similarly, flashings under the field of air conditioners which serviced Evans Computer Room and could not be turned off was quite a challenge, which your able crew was obviously up to.

    Despite the many potentials for difficulty with the above referenced situation and having to triple handle some of the roofing materials, this job went quite smoothly and I know the client and Roofing Inspection Services are quite happy with the work.

    With completion of the roofing work on the project near, this letter is to commend Knickerbocker Roofing and Paving Company for providing a high-quality roof under less-than-ideal conditions and within a tight budget.

    You will recall the roof was to be installed over an existing, difficult substrate, using Knickerbocker’s suggestions which were approved by the roofing material manufacturer and design team; the completed installation met or exceeded all expectations.

    Thanks for your help and cooperation on the project.

    In pre-qualifying the bidders for this $535,000.00 project, I focused on well-established local firms with an in-house sheet metal shop and a strong base of repeat clients. Knickerbocker had excellent references and a wide range of experience in built-up coal tar systems and Sarnafil PVC membranes.

    Knickerbocker provided a competitive price and the work was performed between July and October, with three different crews that specialized in built-up roofing, Sarnafil membranes and sheet metal work. It was apparent that each crew was supervised by a well trained and experienced foreman who had pride in the quality of the finished product. The training and team spirit of each member of the crews was apparent as they worked quickly and efficiently to produce a good product.

    Re-roofing a fully occupied building always created logistical problems and complaints about “inconveniences”. Your workers were always courteous and accommodating in solving these problems.

    In particular, I appreciated the willingness of your sheet metal fabricators and installers to work with me in designing a variety of specialized shapes to solve the original detailing problems.

    In the three months since the job was completed, we have experienced several rain storms with blowing wind, but no leaks in the new roofing systems. Your company’s attention to detail was instrumental in finally ending a twenty (20) year history of roofing problems at this project.

    Thank you for a job well done.

    Knickerbocker Roofing & Paving Company installed a new rubber roof at Thorndale Beach South Condominium in August of 1985.
    The roofers were neat and clean and the workmanship was excellent. I certainly would recommend Knickerbocker Roofing to my fellow building managers.

    I would like to compliment your firm for the professional manner in which you handled our recent roofing projects. Replacing over one million square feet of roofing materials was no easy task, yet the project was completed in a timely fashion. I was impressed with the professional approach you and your firm exhibited throughout the project.

    In particular, your successful completion of the two roof areas, which could only be accessed through the Chicago Transit Authority (C.T.A.) Executive Offices and the Haworth Furniture showroom, displayed your sensitivity to completing the project without disruption to our tenant activities.

    I thank you, and it was a pleasure to work with you and your fine personnel.

    I would like to inform you that Deerfield School District 109 and this office think the workmanship on the project was excellent. Coordination efforts by Mac, as well as the quality of installation and concern for detail by your Foreman, Miles, is clearly evident. I only with that all projects went so well.

    On behalf of School District 109 and Legat Architects, thank you for working towards excellence in roofing.

    Although we can be quick to complain, we seldom take the time we should to say thank you for a job well done.

    This letter is to say just that. You and your employees have shown us that we made a wise decision in choosing Knickerbocker to replace our high-rise roof at 200 West Monroe.

    Apparently the product and installation were appropriate for our job since we survived the heavy spring rains this year without incident.
    We appreciate your expertise, professionalism and efforts in providing a quality finished product for this property. We will recommend your services to the entire property management team at Cushman & Wakefield.

    The members of your construction team did an outstanding job performing work while we continued to train more than 250 firefighter candidates, 25 lieutenant candidates, 50 paramedic in charge. We also continued to run our daily operations for drivers training, rope rescue classes and training for fire department incumbent members. Mike Bafia, Superintendent from Knickerbocker Roofing and Paving, should also be commended on all their hard work keeping us water tight during the roof replacement portion.

    I just wanted to take this opportunity to let you know how much it was a pleasure to work with Knickerbocker roofing. I am able to say this due to working with your Superintendent (Mike Bafia), your foreman and all your other workers who were on this job from sheet metal workers, roofers to the apprentices. Everyone was very diligent and courteous in getting the contract work, extra’s, and punch list work done. Mike helped out with giving his input on how to get things done faster, cheaper as well as serve the same outcome that the architects were looking for. I just thought that you might like to end the week with a positive input about your field personal from Bulley & Andrews. I have taken the same measures to let my office know as well.

    On behalf of the Board of Trustees, as well as the entire congregation of our church, we would like to extend to you our most sincere thank you for the excellent experience we’ve had with your company through the course of the roof replacement project. The quality of work and resulting visual improvement to our cherished building has exceeded our expectations. We are left with no doubt that we made the correct choice in selecting Knickerbocker for this project.

    We would also like to acknowledge the way in which Ed Scaggs and all of the crew onsite conducted themselves through the project. They held a consistent sensitivity for the safety of those using the building during working hours and minimized noise when certain areas of the building were in use. I received only compliments on their interactions with church members and staff.

    Again, thank you, and best wishes for continued success.

  34. In-House Sheet Metal Fabrication Drives Consumer and Company Success

    Leave a Comment

    As we all know, replacing or renovating a roof isn’t a stroll in the park. It’s fairly expensive and often time-consuming – especially if the fitting, detailing and the execution aren’t done right.

    In an industry that is challenged by the problem of low customer satisfaction ratings, Knickerbocker continues to be a luminary – taking one project after another to a sterling finish, often highlighted by our outstanding sheet metal finishes.

    From generic installations to more elaborate, ornamental designs,  specialty items to spires and colonnades, copper to stainless steel and prefinished variants in an array of colors, Knickerbocker is known for timely project completions, faultless craftsmanship, impeccable sense of design, and sheet metal installation.

    In-House Fabrication Stands for Flexibility & Cost Effectiveness

    We attribute many sheet metal project successes to in-house fabrication instead of outsourcing project requirements to other companies.

    • In-house fabrication allows Knickerbocker unparalleled control over the sheet metal fabrication.
    • For this process we have access to copper, stainless steel, galvanized, and numerous prefinished metal flat sheets to delight customers with possibilities and undertake ambitious projects like the roofing of the River City Condos.
    • Because Knickerbocker manages this sheet metal fabrication, we avoid supply chain bottlenecks like miscommunication, inventory synchronization issues, and poor workmanship of the supplier which culminate in unavoidable delays and customer frustrations.

    These advantages are backed by the experience and expertise of our internally sourced tradesmen who are well versed with industry best practices and can troubleshoot installation complexities as they arise.

    The end result is a quality solution that is perfect in terms of the cut, fit, and on time delivery for a rewarding customer experience.

  35. National Safety Month: Fall Safety and Prevention

    Leave a Comment

    Since the day we were founded in 1886, Knickerbocker Roofing has strived to play an active role in our community, providing comprehensive safety training and education. Specializing in slip and fall safety, our expert team is committed to enhancing overall safety in the roofing and construction sectors.

    While we focus on safety year-round, there is no better time to highlight our efforts and good safety practices than in June, National Safety Month. Organized by the National Safety Council (NSC), National Safety Month aims to raise awareness of safety practices in order to reduce workplace injuries and fatalities.

    This year, the first week of National Safety Month is centered on the theme “Stand Up to Falls” — particularly pertinent to our industry. According to the Occupational Safety and Health Administration (OSHA), falls are one of the most common causes of work-related injury and death. In the construction, contractor, and roofing industries, workers are regularly at risk of falls. OSHA lists a variety of fall-prevention safety regulations, but regulations are often overlooked — or ignored for the sake of expediency.

    With over 75-100 ongoing employees, Knickerbocker is proud to be a pillar of our community. It is our responsibility to keep both our employees,  customers — and by extension, our entire community — safe from the dangers of slips and falls. This is a responsibility we take very seriously.

    National Safety Month: Fall Safety and Prevention

    To help keep your employees safe, here are a few tips pulled straight from the Knickerbocker safety playbook:

    • Train all employees in safety procedures regularly (at the very least, annually).
    • Require employees to use all relevant safety gear at all times while on-site — no exceptions.
    • Focus on individual safety aspects (ex: scaffolding safety) to ensure workers have thorough knowledge of various measures.
    • Require compliance checks by project supervisors.
    • Have independent safety consultants perform regular site inspections.
    • Upgrade to modern equipment whenever possible.
    • Maintain equipment carefully, thoroughly, and regularly.

    These are just a few of the common-sense safety procedures we adhere to at Knickerbocker Roofing, and we urge you to follow them as well. Knickerbocker Roofing is working hard to promote National Safety Month both locally and nationally, as we consider it part of our job to reliably protect our workers and the community at large.

  36. What You Need to Know in Roofing Now That Spring is Just Around the Corner

    Leave a Comment

    Here at Knickerbocker Roofing, we’re excited to be welcoming in spring! Not only is the green growing back, but longer days and warmer temperatures make the season that much more inviting. With the change in season also comes a good opportunity to check out any damage that may have been done to your roof during the cold winter months. Snow, ice and winds can cause damage that can be hard to see unless you’re looking directly at it, and putting off repairs can lead to even further damage.

    Roofing maintenance is an important part of home and building ownership, and with National Roofing Week coming up June 4th-10th, there’s no better time to get started. For any home or business owner, there are a few simple steps you can follow for spring maintenance and repair:

    1. Spring-Maintenance-4.19.17Clean your downspouts and gutters, but remember safety first. Don’t use a rickety ladder or put a ladder on uneven ground.
    2. Clean out large, visible debris first, then clean out smaller fragments with a garden hose.
    3. Visually inspect your roof, looking for buckling or curling in the shingles. This can mean they need to be replaced.
    4. Inspect the areas around any chimneys, pipes, roof drains, or HVAC connections for any penetrations on the roof.
    5. On the inside, you can look for water damage on the ceiling or in the walls. Water damage is usually noticeable and causes slight to moderate staining.
    6. If you’re not comfortable getting on your roof, call a credible contractor.

    While there are many maintenance issues business owners can take care of themselves, roofing inspections are commonly best left to a professional. Not only can a roofing expert pinpoint problems or potential issues, but they can figure out the best course of action to fixing the problem. At Knickerbocker Roofing, we’ve been a family owned business for over 125 years, and we look forward to working with business owners to provide roofing solutions.

    We invite you to read our blog, follow us on Twitter, and connect with us on LinkedIn. As experts in the roofing industry, we look forward to meeting you and exceeding your expectations.

For us at Knickerbocker Roofing, this proved to be another successful year, as we proudly promoted workplace safety, responsible building techniques, and seasonal protection solutions.

    Inwardly, the Knickerbocker team sets sights on important trade shows to expand our already remarkable knowledge of the industry. And 2017 will be no exception as we’ve already hit the ground running.

    To kick off the new year, our team attended the Chicago Roofing Contractors Association (CRCA) Trade Show & Seminars January 19th-20th. The 34th annual trade show was held at the Drury Lane Conference Center in Oakbrook Terrace, Ill., and featured expert keynote speakers, educational breakout sessions, and nearly 200 exhibitors showcasing on the expo floor.

    The sold-out 2017 CRCA Trade Show proved again to be one of the biggest events in the industry; top leaders from all around the region gathered under one roof to discuss the latest trends and innovations in roofing. Our team was particularly excited to learn about new roofing technologies and what to expect this year.

  39. CRCA Brings the Industry Together Under One Roof

    Leave a Comment

    What’s the benefit of belonging to a local trade organization? For us here at Knickerbocker, they are many. As a long-standing member of the Chicago Roofing Contractors Association (CRCA), we can testify to the valuable services and resources the CRCA offers its members and the customers we serve.

    So, what is the CRCA? It’s a local trade association that serves the construction, roofing, and waterproofing industries across the Chicago area. Members come together to discuss and solve issues important to the roofing industry. They are from all sectors of the industry such as contractors, manufacturers, and representatives – forming a well-rounded group of professionals to learn from and network with.

    The association is active in sponsoring events for understanding important aspects of the industry including industry affairs, safety standards, and new technologies and products. The next big event we will be attending is “Roofing Week in Chicago—Weighing the Facts!” This CRCA sponsored trade show and seminar takes place on January 19th and 20th at the Drury Lane Conference Center in Oakbrook Terrace, IL.

    Expert panels will address topics such as attic ventilation, building envelope research, lightweight structural concrete, equipment safety, and code requirements. The takeaway from these seminars adds to our already deep knowledge of the industry. We are strong believers in learning and exploring new ideas and expanding our current knowledge base to the benefit of our employee and customer base. The field is diverse and constantly growing. CRCA helps us stay current on what’s happening throughout the Chicagoland area and the industry.

  40. End-of-the-Year Recap: A Look Back at 2016

    Leave a Comment

    With the holidays upon us, we at Knickerbocker Roofing and Paving Co., Inc. are taking the time to look back on the past year’s accomplishments. To recap some of our most important news, we’ve highlighted blog posts that detail recent achievements and outline our commitment to sustainable, environmentally friendly roofing solutions. Take a look below:

    Blog Highlights

    Our Commitment to Sustainability

    As an advocate of green roofing systems, we thought it was important to share our knowledge on responsible building practices in honor of Earth Day this past year. In April’s blog post, we discussed the benefits of green roofs, or “living roofs,” which are partly or completely covered with a waterproof membrane, a growing medium, and vegetation. Besides providing an aesthetically pleasing, elegant but modern design, these roofs reduce energy consumption and improve water efficiency.

    In another post, we delved into the benefits of white roofs — roofs constructed from white materials with reflective coatings. Common materials include polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO). These materials push back solar rays and help keep the roof — and therefore the interior of the structure — cooler during hot months.

    Keeping People Safe Across Industries

    At Knickerbocker, we’re serious about client safety and are committed to providing reliable, practical solutions for all types of industries. For instance, we have extensive experience providing school roof inspections, repairs, and installations; in our August post, we encouraged schools to contact us for a free consultation in order to prevent issues and safety hazards during the school year. And if things do go wrong, we have a 24/7 emergency service hotline to address issues around the clock.

    During National Safety Month in June, we outlined the steps we take to provide optimal fall protection. Utilizing the OSHA Fall Protection in Construction guidelines, we continually improve our safety procedures and invest in the highest-quality fall prevention and protection equipment. As a participant in National Safety Month and OSHA Stand Down, we conduct regular safety meeting, discuss job hazards with employees daily, and hold an annual safety training program for all workers.

    Looking to 2017

    As the year draws to a close, we at Knickerbocker are evaluating 2016’s successes, and, as always, are looking for new ways to improve our processes and better serve our clients. We hope everyone has a great holiday season and a happy new year. We’ll see you here in 2017!

  42. Knickerbocker Roofing and Paving Offers Waterproofing Capabilities

    Leave a Comment

    knickKnickerbocker Roofing has been in business for over 125 years offering industrial, commercial, and institutional roofing solutions, including inverted roof systems and vegetative roof systems. Inverted roof systems are designed to protect the roof from excessive weather conditions which are prevalent in some areas of the country, while vegetative roofing systems are designed to have a garden or other vegetation on it. Both roofing types can better protect the roof and provide a high return on investment.

    Using an inverted or vegetative roofing system means the waterproofing membrane is buried underneath the system. Unlike traditional roofs that are easily accessible, inverted and vegetative roofs can be nearly impossible to access, making it important to use a quality material to protect the roof at the time of installation.

    Although the membrane is necessary to protect the roof, it can be burdensome to make repairs when leaks happen. When you choose Knickerbocker to install one of these roofs, you get a quality waterproof membrane that is installed by highly skilled craftsmen and women to prevent difficult repairs that are hard to reach. Any system that is paved over, has a garden or vegetative roof, or decking can be waterproofed.

    The professionals at Knickerbocker understand roofs and know how to design and construct the right roof for any job. They have extensive experience with green roofs and can work under tight deadlines to get the roof up and ready as soon as possible. They are also able to install Electric Field Vector Mapping Systems (EFVM) which are a high-quality tool for investigating leaks to quickly solve any water leakage problems that might occur.

    If you’re interested in learning more about one of these high-quality roofing systems, contact any of the professionals at Knickerbocker today. They can provide you with a quote for the right roof for your building structure.

  43. Prevent Leaks Before the End of Fall and Start of Winter

    Leave a Comment

    When you find water dripping into your kitchen, it’s too late – the leaks have already
    prevent-leaks-image-oct-2016    started. Here in Chicago, we start seeing heavy rains coming down in September, which of course leads us to the winter months and the snow that comes with it. Your best bet is to be proactive, and take a look at your house or business for potential leaks and necessary roofing repairs before the rain starts falling.

    Our Local Weather

    Chicago has seen plenty of poor weather in the fall and winter over the years, and the worst part is it can be so utterly unpredictable. For instance, last year, we saw one of the wettest Septembers in a while followed by a drier-than-normal October. It’s not just rain, but also snow – November saw a full 10 inches more snow than average, bhttps://www.weather.gov/media/lot/events/2015/climate/2015_Chicago.pdfut December followed with four inches less than usual! You never know what the fall and winter will bring, but one thing we can guarantee is that, as every Chicagoan knows, it will be brutal.

    Common Causes of Roof Leaks

    The best thing you can do is give your business an inspection for the variety of conditions that can cause roof leaks. These can include, but aren’t limited to:

    • Rotting or rusting materials on the roof
    • Punctures in the roof
    • Cracked flashings
    • Poor roof drainage
    • Penetrations that extend through the roof, including chimneys, skylights, plumbing vents, and more

    Getting up on your roof and evaluating these factors in August or early September will get you ahead of the game, and can help avoid nasty, wet messes when the rains come. Of course, if you fail to prevent a leak, you can always reach us when you need help ASAP, at our emergency service hotline.

    Here at Knickerbocker, we have an annual roof maintenance program that can help you address your roof, keeping it clean and clear of debris, while maintaining drains, gutters, flashings, and more. Our visits also include inspection of mechanical equipment flashings and inspection and repair of the field membrane. These visits can drastically reduce the likelihood of a leak, and keep water where it belongs – outside. Of course, you can avoid that by getting in contact with us today to see how Knickerbocker Roofing can keep you dry through the coming months!

  45. Natural Sunlight Enhances Interior Spaces

    Leave a Comment

    The art of roofing combines skill, experience, and insight into each building’s form and Natural Sunlight Enhances Interior Spacesfunction. The skills required to install a high-quality and long lasting roof also include expert sheet metal fabrication and installation. At Knickerbocker, we are experts in all types of roofing installations including taking on the challenges of designers wishing to create productive and visually stimulating interior environments.

    A recent addition to building design is the concept of “daylighting.” By controlling the admission of direct and diffuse sunlight, there is less dependence on electric lighting during daytime hours which reduces energy use. With the sun as the primary source of daylight, it seems like an obvious choice to consider adding skylights. Skylights have been used for years to let natural light penetrate the interior of a building. Natural light enhances human health and performance by affecting the body’s circadian system. This has been shown to improve mood and perception while also encouraging the body to produce Vitamin D. Today’s modern skylights offer many positive benefits.

    Combining the use of skylights with daylight-responsive lighting controls offers the highest energy saving options. Many building owners and corporations are installing daylighting systems and realizing large savings on their electric bills. Walmart, for example, incorporates daylighting systems in every facility they are building or converting. Skylights allow them to use light sensors to dim automatically or turn off the lights during the day reducing electricity demand during peak hours. They estimate annual savings of approximately 250 million kwh.

    The addition of skylights requires reliable contractors who understand the processes involved in this type of installation. Once the roof is penetrated the skylight must be sealed properly to prevent water or air leaks. The roofing around the skylights must be secure, and proper maintenance must be performed to ensure long-lasting results of the whole system.

    Knowing the ins and outs of the industry, our team understands how to get the job done safely and effectively. As architectural and ornamental design experts, Knickerbocker’s extensive roofing capabilities enable us to enhance the atmosphere of the inside of the building while also reinforcing the outside. If you are considering adding a daylighting system and skylights, contact Knickerbocker to let the sun shine in!

  46. Knickerbocker Reviews Fall Safety this June

    Leave a Comment

    Worker safety is always at the forefront of what we do here at Knickerbocker Roofing. We want our employees to be aware and alert of the dangers they face on a regular basis and to work with us to reduce the possibility of an accident, minor or major.

    National Safety Month and OSHA Stand-Down

    Each June, the National Safety Council observes National Safety Month. While every month should take a look at safety, this month concentrates on increasing the awareness of leading safety and health risks in venues including the workplace, home, local community, and traffic. By providing materials including posters, tip sheets, and more, the NSC aims to educate about the leading causes of injury and death, and to reduce them.

    Just as important in our line of work is the OSHA Stand-Down event, which took place this year on May 2nd through the 6th. With the nature of our labor, fall safety is very important – particularly because falls are the leading cause of worker death and serious injury in the construction industry. Each year, the Stand-Down event involves having a toolbox talk or safety meeting for fall prevention and protection. OSHA’s goal this year was to reach 5 million workers throughout the Stand-Down week.

    Fall Protection

    Every day, our teams utilize practices to prevent falls. On a regular basis, we conduct safety inspections of our worksites and our employee practices and provide correction when needed. Utilizing the OSHA Fall Protection in Construction guidelines, we are constantly revamping our procedures to exceed the standards they advise. On top of practices, we also ensure the usage of the latest in fall prevention and protection equipment and make sure that it is properly maintained.

    Our Involvement

    At Knickerbocker, we participate in both National Safety Month and OSHA Stand Down by conducting safety meetings, discussing specific job hazards our employees face on a daily basis, and implementing response plans. Ways we work to improve employee safety include:

    • Annual Safety training program for all field and supervisory employees
    • Project safety inspections by independent safety consultants
    • Utilization of modern equipment, maintained for safe usage by our mechanics

    In a high-risk industry, you need to pay constant attention to safety. For the well-being of our employees, as well as the peace of mind of our customers, here at Knickerbocker Roofing and Paving we promise to continue to be involved in keeping our employees safe, and continue the programs that have earned us awards including the American Subcontractors Association Safety Award and the Chicago Roofing Contractors Association Safety Award. Join us for National Safety Month – along with the rest of the year – in an effort to make safety important in all aspects of work and home.

  47. Befriend Your Roofing Contractor Before the Storms this Season

    Leave a Comment

    After the rough of winter, spring has finally started to blossom across the Midwest. Although the temperatures are growing nicer, damaging storms are still a relevant concern year round. A new report finds that heavy rainfall from storms are continually causing major flooding and tornado clusters are becoming much more frequent. Peak tornado season ranges from April-June and thunderstorms occur most commonly from June-August.

    So, before we head into that next weather cycle, take the time and make the effort to reach out to your roofing contractor. Developing a relationship early on can lead to a better roofing experience, overall. Customers that remain in steady contact often encounter less damage to the interior and exterior structures because their roofing issues are addressed ahead of time. This means taking the initiative to inspect your roofing system in between the seasons to ensure that last winter’s snow and ice didn’t leave any serious harm behind. Not only can contractors assist in fixing existing problems, but they can help to prevent future problems from occurring.

    Intense summer storms, many a time, blow into town leaving high winds, lightening, pouring rain, and the occasional hail in its path. A roof maintenance program, as mentioned in our November post, is a viable option that can help save time and money. By fixing smaller problems along the way, you might prevent a bigger problem that lies ahead. At Knickerbocker, we work with each of our clients to design a maintenance program that fits your needs and budget.

    We all know summer weather can be inconsistent and turn from a harmless storm into a raging disaster within a matter of minutes. Having a relationship with a trusted roofing contractor means that you know who to call when a serious problem does occur. Even with the best preparation, strong storms can be detrimental. Having a company you know will respond quickly in an emergency is having peace of mind. Knickerbockers 24-hr emergency service hotline is standing by to answer to commercial, industrial, and institutional clients who require help ASAP.

    When you take a moment to step back and think about the essential functions of a roof, it becomes clear that this is the barrier that protects our loved ones and most valued assets from harm’s way. With unpredictable and severe weather affecting us year round, roof repairs are becoming more and more common. Take the next step to prepare and remain in control of your property.

    Are you ready to build a relationship with a roofing contractor? Look no further. The experts at Knickerbocker are standing by, set to make sure we take care of all of your roofing needs. Contact us today by clicking here or calling 708-339-7260.

  48. We Celebrate Responsible Building Practices in April!

    Leave a Comment

    In our last post we gave you the ins and outs of Earth Day and how it is a reminder to consider the environment in all decisions we make throughout our daily lives – sound familiar? Since it is finally April and Earth Day is fast approaching we are seizing the opportunity to tell you about additional roofing materials and systems that benefit the environment.

    Green roofs, also known as living roofs, are partly or completely covered with a waterproof membrane, a growing medium, and vegetation. They are an environmentally friendly roofing system that aims to reduce energy consumption and foster the idea of green cities. The addition of a green roof system helps to improve energy and water efficiency, while reducing pollution. Green roofs have a focus on water retention and also protect the roof from damaging solar rays.

    Because the system thrives on living plants, a direct result of the sun and rain, the roof becomes not only functional but aesthetically pleasing to the eye. These types of installations help keep buildings cool because the plants absorb the sun’s rays. This reaction leads to lower HVAC use in the summer. On steep sloped roofs, slate and tile are roofing materials that are natural products that can be recycled back into earthen material. These products have a lifespan of about 75-80 years. Green roofs are made up of long lasting materials that lead to lower replacement costs over the years, benefiting both you and the environment!

    We are true advocates of green roofing systems and have been involved in quite a few installations. There are many challenges involved in designing and building a green roofing system that is successful for both the environmental and the building sectors. Keep that in mind when choosing your roofing company… With our experience, we can take on wide variety of green roofing projects that help the environment and the community prosper.

  49. Earth Day Prompts Us to Save Energy

    Leave a Comment

    April 22nd is the worldwide celebration of Earth Day which reminds us all of the importance of taking actions that save energy, the climate, and the Earth. This year marks the 46th anniversary of the movement that spurred us into action to tackle environmental issues in all parts of our lives.

    A basic campaign of the Earth Day Network is to create green cities so we can live more sustainable lives. Using green building materials to encourage energy efficiency is a strategy for reducing energy consumption in buildings by 30-80%. An area where this can have a dramatic impact is in roofing materials. White roofs (also known as cool roofs) are made from reflective materials that reduce heat transfer to the surface. This keeps the heat from penetrating to the interior of the building, reducing the amount of air conditioning needed to cool the building in the summer. White roofs are beneficial to green cities by reducing local air temperatures and lowering electricity demand and energy generation. In hotter climates these roofs reduce urban heat and keep buildings cooler at night unlike black top, pavement, or dark roofing materials that absorb heat during the day and cool down very slowly after sunset.

    The material used in white roofs can be made from materials that are white in color or materials that have been coated to be reflective. Some ideal materials include EPDM which is a rubber roofing material used on flat and low-slope roofs and is available in white; PNC roofing which is reflective and can provide energy efficiency, and thermoplastic polyolefin (TPO) which is growing in acceptance. All of these materials push back the solar rays keeping the roof cooler on scorching hot days.

    Knickerbocker has been involved with many green roofing installations and our specialty roofing capabilities will improve LEED certifications and help create green cities, reduce energy consumption, and be environmentally conscious. Contact us to learn more about white roofs and how they can improve your building’s performance today.

  50. Knickerbocker Attended the International Roofing Expo This Month

    Leave a Comment

    The International Roofing Expo (IRE) is a premier roofing construction and maintenance event for roofing professionals that took place February 17th-19th at the Orange County Convention Center in Orlando, Florida.

    Annually, this industry event is where professionals get to network with other industry experts, see and learn about new products and innovations, and attend conference sessions and educational classes that expand our knowledge base while improving skills. Over 475 companies exhibited multi-dimensional products, services, new technologies, innovations, and ideas that were and are designed to improve the roofing construction and maintenance industry.

    Our President, Mark Moran, walked the floor at the expo and met with manufacturers and service providers to explore what’s new in 2016. He also attended educational seminars to expand his knowledge of the industry and brought back information to help us better serve our customers.

    This was an important event for us as it was the ideal time to network with like-minded industry professionals. It isn’t too often that the top names in roofing construction get the chance to gather together, so when we do it is the perfect time to highlight our capabilities and showcase our skills to the rest of the industry.

    We were thrilled to meet old and new clients and connect with other’s in the industry while we were all under one roof. We look forward to seeing you there next year!

  51. Looking Forward to the Year Ahead

    Leave a Comment

    The 2015 season is officially over, and now that the first of the year has passed we’re gearing up for what will develop in 2016. Our industry has been rebounding nicely from the recession and 2016 is expected to continue this trend with growth in both commercial and residential construction.

    According to the Associated Builders and Contractors (ABC) forecast, the roofing and construction industry should expect to see nonresidential construction spending grow 7.5% this year. Contractor confidence has increased and backlog indicators also signal strong demand. The Dodge Outlook Report predicts that new construction starts will rise 6% overall. By sector, the new construction breakdown is expected as:

    • A 20% rise in dollars for single family housing corresponding to a 17% increase in units.
    • A 7% rise in dollars for multifamily housing corresponding to 5% increase in units.
    • An 11% rise in commercial building.
    • A 9% rise in educational buildings including schools and hospitals.

    This positive picture of the industry is indicative of rebounding markets, improvements in the economy, and increases in job growth. As an election year, 2016 should also see an increase in capital improvement projects as state budgets have allocated more spending for infrastructure. The collaboration with private industry has led to more public-private partnerships (P3) which enable government agencies to better afford large capital construction projects. P3 offers a broad array of options and are a viable option for financing and managing construction projects.

    Experts are also predicating a banner year ahead for the remodeling sector, with the strongest growth in the luxury market and an increase in adoption of green building. Residential remodeling and green building are in demand as consumers want higher quality results and ways to reduce living costs. Residential construction is catching up to the commercial sector in green principles.

    The predictions for the coming year are very promising and align with what we have been experiencing. Knickerbocker is seeing growth in the market, and general improvements in the industry, as residential and commercial projects seek the highest quality roofing and construction capabilities. We are a leader in architectural sheet metal fabrications, steep slope roofing, low slope roofing, and green roofing services. Our specialty roofing capabilities set us apart from others in the industry.

    The Knickerbocker team wishes all of you a Happy New Year and look forward to the new challenges of 2016. Contact us today to learn how our capabilities can set you apart from the others in the new year!

  52. Avoid Adding Roofing Problems and Repairs to Your List of Winter Woes

    Leave a Comment

    Here in the Midwest, we’re accustomed to the cold winter temperatures, howling winds, snow, and ice, but that doesn’t necessarily mean we like them! Our list of winter woes can be long and we certainly don’t need to add more problems to the list. Hence the reason it is so important to properly maintain and keep a vigil eye on your roof in the 2016 winter months.

    The National Weather Service said that January 2015 was an exceptionally cold month around this area and 2016 isn’t looking much warmer. Last winter, a report on USAToday.com stated, “It’s been a brutally cold month across much of the nation’s northern tier… In Chicago, temperatures are about 10 degrees below average for the month, and the city is suffering through an even colder January than last year, during the infamous polar vortex…” There seems to be a pattern building here…

    It’s not just the cold temperatures that are affecting us – and also affecting our roofs and the roofs of businesses throughout the area. Last year, it was the fluctuating jet stream that brought in warmer temperatures every so often, that caused additional trouble. Freeze-thaw conditions caused by the jet stream maneuvers (when the cold outside warms up and then suddenly drops again) can wreak havoc on roof systems, creating leaks. When it comes to roofing, whether temperatures are mild or cold, it seems that both are an issue.

    Standing moisture on a roof system can also present problems. Just as constant contact with moisture is bad for windows and masonry, it can also be detrimental to roofing membrane and flashings. To prevent damage to your roofing system, it’s wise to keep an eye on your roof at all times and work to prevent excessive snow build-up when possible. Make sure roofing professionals remove the snow from your roof because we know proper roofing safety practices, and are experienced with roof system maintenance.

    In addition to the snow, there is ice. Wherever it’s coming from, ice can damage your roofing system. Roof drains, gutters and flashing can all be damaged by icing and ice chunks falling from adjacent buildings. As a caution, make sure to be on the lookout for possible icing damage when the temperatures dip below the freezing point.

    Today’s last blistering-cold winter weather concern related to roofing: if your roof needs a repair in the winter months, it’s possible that you might have to wait some time. Roofing repairs can’t always be attended to during the winter months as a direct result of extremely cold temperatures, snow, or moisture being present. Contact a roofing professional for their evaluation of the possibilities for repair. It will all depend on your specific roof system, the damage you have, the repair required, and, of course, the current winter weather conditions at that time.

    Overall, the best possible solution is year-round maintenance of your roof. To be safe and smart, today is the perfect time to schedule a roof inspection for the worsening winter months, and fully address any damages from the last several. Being safe and smart with Knickerbocker is always a good idea – and it can keep you from adding to your list of winter woes!

  53. Be Prepared for “Above Normal” Snowfall in Chicago in 2015-16: Prevent Roof Leaks with an Annual Roof Maintenance Program

    Leave a Comment

    As discussed in our October blog post, “Prevent This Year’s Roofing Leaks from Rain and Snow,” the snowfall this year is appearing to be one for the record books. Look to ready yourself for the winter months and prevent roof leaks at your facilities, every season of the year, with a roof maintenance program like the annual roof maintenance program we offer at Knickerbocker.

    In addition to preventing roof leaks, Knickerbocker’s roof maintenance programs are designed to fit our customers’ needs and budget. Note that, in the long run, an investment in an annual roof maintenance program can save you from spending a lot of time and money on repairs. Another benefit of a roof maintenance program is the peace-of-mind you’ll get from knowing that you’ve got everything covered, when it comes to roof maintenance.

    It’s easy to get started with a roof maintenance program with Knickerbocker right away!

    We begin all roof maintenance programs for industrial, commercial and institutional facilities with a routine roof inspection to survey the condition of all building roofs. After inspection, we provide a written report on each roof. The report includes photographed areas of the roof that need to be addressed, and also details work that should be performed. In addition to our annual roof maintenance programs, our Service Department also offers semi-annual programs, and small project roof repairs and replacements.

    Last, but not least, Knickerbocker always offers emergency roof leak repair service; however, with an annual roof maintenance program with us, you greatly reduce the need for emergency service!

    For further information on the above programs, contact us at 708-339-7260 or be sure to visit our website today!

  54. Celebrating 129 Years of History in the Roofing Industry

    Leave a Comment

    Today we are taking a look at history, going back 129 years to 1886*. What was happening in both the U.S. and roofing industry in Chicago? Knickerbocker is here to tell all:

    • The Statue of Liberty, “a gift of friendship from the people of France to the people of the United States,” was dedicated here in the U.S.

    • Grover Cleveland was President of the United States

    • Chicago became the center of a national labor movement, pushing for an eight-hour workday

    • What many might not know is that Bernard Kelly bought Knickerbocker Roofing &

    • Paving Co. Inc. and founded what has now grown into one of the largest roofing contractors in the Midwest

    Some of the earlier Knickerbocker projects included: the Public Library, now known as the Cultural Center and the paving of Michigan Avenue! In the early to mid-1900’s, Mark A. Cronin, Sr., Kelly’s son-in-law, helped expand Knickerbocker into a largely successful sector: railroads. Railroad structures, worn down by the steam and fumes of burning coal, needed continuous deck and roof replacements. Knickerbocker was there to “pick up steam!” and worked for many major rail lines cross-country.

    Fast-forward through five generations, 129 years later, and Knickerbocker Roofing & Paving celebrates its history as a successful family-run business. Four great-grandsons, and one great-great grandson, of the Bernard Kelly lineage are among the latest generation leading the Knickerbocker team of employees. At Knickerbocker, we are a team of trained professionals, remaining as courteous, customer-oriented and friendly as we were 129 years ago.

    Today, we specialize in providing commercial and industrial roofing services to our customers located throughout the Chicago area and Midwest region. Among the range of services we offer are low slope roofing services, steep slope roofing services, sheet metal fabrication, green roofing services, roof maintenance services, plus emergency roof and leak repair services. Additionally, we’re recognized throughout the communities and industries we serve as experienced and reliable roofing specialists. We believe it’s those essential qualities – experience and reliability – that have helped us build a 129-year tradition of trust with our customers!

    Topping things off, it’s not just our customers who know they can rely on us: roofing system manufacturers know us for those same qualities of trust, experience and reliability. In fact, we are proud to say that Knickerbocker is certified by all of the major roofing system manufacturers, as a trusted source to furnish and install their roofing systems as well.

    Here at Knickerbocker, we plan on continuing to provide commercial and industrial roofing services for many more years to come. After all is said and done, if you’re looking for reliable roofing specialists in the Chicago area we will be here, and ready to serve you, just as we were for our first customers in 1886. In the meantime, you can visit our website to learn more about our company and its 129-year history, or just give us a call at 708-339-7260 if you have further questions for us.

  55. Prevent This Year’s Roofing Leaks from Rain and Snow

    Leave a Comment

    October is here and we’re on the brink of some hefty wet weather this fall in the Midwest. The last thing we all want to talk about is the rain, sleet, and snow that will be forecasted as we’ve spent precious moments in the beautiful summer weather these past several months. Still, the roofing industry is here to help you prepare for the leaks and repairs you could run into this upcoming season.

    The first step is being responsible by taking action. Make sure you are prepared to manage and maintain both commercial and industrial buildings, because the harsh weather is bound to affect those who think there is time to waste. According to The Old Farmer’s Almanac, the snowfall in the Chicago area this coming winter “will be above normal in most of the region, with the snowiest periods in mid-December, early [to] mid-January, and early February.”

    Also, always keep in mind that knowledge is power. Know the common causes of roof leaks such as: puncture wounds to various portions of the roof, rotting materials, cracked flashings, broken shingles, poor roof and gutter drainage and installation. Now is the right time to fix existing problems and take preventive measures by making sure your roof is in good condition to handle the up-and-coming unpredictable weather.

  56. Low-Slope vs. Steep-Slope Roof: What are the Differences?

    Leave a Comment

    At Knickerbocker Roofing & Paving Co. we install both! They call us “the experts” because we know roofing like the back of our hands. You might be wondering how we got so seasoned in roofing systems, styles, and selections… With 129 years of experience (yes, since 1886!) we’ve been installing, fabricating, repairing, replacing and maintaining all types of roofing systems, including low-slope and steep-slope roofs.

    Before we jump into the differences between low-slope and steep-slope roofs, let’s take a look at some similarities. Both types of roofs should be installed and maintained properly. The ultimate goal is a safe and secure job site with a quality finish. At Knickerbocker we stick to the slogan “safety first.” As a result, our customers understand that they can trust us with their roofing system installations, repairs and maintenance.

    Low Slope Roofs vs. Steep Slope Roofs

    Now let’s take a look at the main differences between the two.

    Low-slope roofsLow-slope roofs:

    • A roof is considered to be a “low-slope” roof if the pitch of the roof is less than 18 degrees.
    • Low-slope roofs require integral components, including flashing, copings and drains to guarantee drainage and promote a dry, durable, long-lasting roofing system.
    • Insulation, most often polyisocyanurate insulation, offers thermal protection from the cold and heat outside.
    • For low-slope roofs, cover boards offer puncture and additional moisture protection.
    • Underlayment provides moisture and temperature barriers.
    • Acrylic, emulsion, reflective and aluminum coatings add to the durability, waterproofing, and corrosion-resistance qualities of low-slope roofs.

    Steep-slope roofs:

    • A roof is considered to be a “steep-slope” roof if the slope is greater than 18 degrees.
    • The installation, repair and maintenance of steep-slope roofs, with their “steeper” needs, require an experienced, full-service roofing company with comprehensive steep-slope capabilities.
    • Steep-slope roofs require underlayment that is appropriate for application.
    • Additionally, we can recommend the appropriate sheet metal to deliver a complete watertight and aesthetically pleasing steep-slope roofing system.
    • Steep-slope roofs are often dramatic and eye-catching.
    • They can be designed and installed with a wide variety of materials, including slate, tile, wood shakes or shingles.

    One of the most recent examples of our low-slope installation work can be seen at the Zurich Insurance Office Buildings. The new roofs (totaling over 55,000 square feet) are comprised of modified bitumen roofing over tapered insulation. Also, make sure to check out the historic Monroe Building in Chicago. Their clay tile roof and copper gutter installation is one of our favorite steep-slope roofing projects! For more examples of our work, take a look at our website.

    At Knickerbocker, whether you choose a low-slope or a steep-slope roof, we’ll be happy to help you install it! As trusted roofing experts, we stand behind all of the work we do and offer a guarantee on all of our services. Contact us to learn more details about our low-slope and steep-slope roofing services.

  57. Common Myths About Roofing & The Facts That Dispel Them

    Leave a Comment

    President Abraham Lincoln once said, “I am a firm believer in the people. If given the truth, they can be depended upon… The great point is to bring them the real facts.” Lincoln’s theory holds true in regards to most circumstances, including roofs and roofing services. Facts can help to dispel common myths and concrete facts (no pun intended) will help you when it comes time to make the right decisions about your roof. Over the years, a lot has been said about roofing; both commercial and industrial roofing, and residential too. Because there is so much information out there, a lot of roofing myths tend to circulate. To clear up some of these common misconceptions, we’re presenting the roofing facts! Read on:

    Myth: You will save money by taking care of repairs after the damage is already done.
    Fact: You will save money by taking care of repairs before the roof leaks.
    What the experts say: A roof is the building’s first level of protection against the elements – rain, wind, sun, and snow. An article from the Chicago Tribune quoted an executive from the National Roofing Contractors Association stating, “No one thinks anything of the roof, until it leaks.” We recommend staying on top of your roof before it leaks because it can prevent further and larger damages that often times go unattended. By being proactive you can save money on some of those major repairs and expenses.

    Myth: Your roof does not need annual repair reviews.
    Fact: It is wise to survey the state of your roof (commercial, home, industrial, or institutional) regularly.
    What the experts say: At Knickerbocker, we recommend annual, or biannual, inspections to our customers. Why? Frequent examinations with written guidance reports and photos allow you to examine concern areas that should be addressed sooner than later. The per-project agreements that we offer grant ongoing roof inspections to ensure your roofs longevity and that it is properly maintained. Again, this will save you money on the inevitably big repairs you will need if you wait on inspections.

    Myth: Damaged shingled roofs have a quick fix. Simply cover the existing layer with new shingles.
    FACT: The above will NOT fix the problem, it will only create further damages in the future.
    What the experts say: Instead, old shingles should be entirely removed and replaced. Some building codes might say that the above myth is acceptable, but it is not a good idea! Head back to the article referenced above, “Think of shingles as the skin of an apple. Ever bite into that bright red skin only to get a mouthful of a soft, bruised, mushy interior? Underneath shingles is a layer of wood sheathing, usually plywood. Sheathing can rot because of leaks, inadequate attic ventilation or just age. The best way to inspect this critical layer is to strip away the old shingles.”

    Myth: Green roofs are a pricey rip off.
    FACT: Green roofs offer many advantages when properly installed.
    What the experts say: A recent blog from the Huffington Post commented, “Green building isn’t as difficult as you might think…” and we would agree with this statement, adding, when it’s done right. Just one of the huge advantages of a properly installed green roofing system is the prevention of leaks. At Knickerbocker Roofing and Paving, we apply our 125+ years of experience in the roofing and sheet metal industry to every green roofing installation we do. In recent years, we’ve completed many successful green roofing installations. Through our relationships with roofing manufacturers and sub-contractors, we’ve become a leader in constructing watertight green roof systems.

    As industrial leaders in the roofing industry, we remind you that these are only a few of the many myths that can lead to further damages or poorly functioning roofing systems. We would be happy to tell you more! For further information on the above, other myths, or general questions and information, give us a call at 708-339-7260 or email us at: sales@knickroof.com. We hope that you take the above information with you on your future roofing endeavors!

  58. Honored By the Recognition We Have Received as a Leading Contractor in the Roofing, Sheet Metal and Waterproofing Industries

    Leave a Comment

    Here at Knickerbocker our progress reflects our birth in 1886. The awards that we have received over the years ultimately recognize us as a leading contractor in the roofing, sheet metal and waterproofing industries.

    Many industries, including our own, have changed throughout the years, but our company’s mission remains strong: to provide outstanding solutions to our customers by offering quality products installed by skilled professionals. At Knickerbocker Roofing and Paving, employers and employees alike consistently strive to maintain our leadership role in the industry.

    With that said, we are proud of our record throughout the years and honored to be recognized for our accomplishments. The awards received include:

    • Project Awards
    • Industry Awards and Certificates
    • Manufacturer Awards and Certificates
    • Safety Awards and Recognition
    • Charity Awards and Certificates

    Here is a brief overview of each category:

    Landmark Preservation Awards
    The ability to restore historic structures is a skill held by only a few companies. Because we are one of those companies who understand the importance of preserving history and we have the capabilities to do so, we are often called in to work on projects with historic and cultural significance. Three projects we have been involved with have been recognized with Chicago Landmark Awards for restoring, reusing, and promoting the city of Chicago’s historic architecture. Landmark Awards have been won with:

    Lorado Taft Midway Studios: This challenging project consisted of small, low sloping roofs with skylights. All existing roofing material was removed and replaced with new Vermont slate, architectural shingles, and copper metal valleys to restore it to the original design. A deteriorated cupola was rebuilt and replaced. The building also houses a working art studio where we installed 12 custom fabricated skylights to enhance the studio with natural sunlight.

    Indian Boundary Field House: Restoration of the fire-damaged building consisted of removing and replacing the multi-colored, multi-width, rescinding slate roof along with new copper sheet metal flashings, valleys, gutters, and downspouts. The challenge of working with multi-color rescinding slate requires skill and expertise to properly install the large slate at the eaves with progressively smaller slate tiles installed toward the top ridge.

    Monroe Building: The steep slope on this occupied office building required exceptional skill and planning to avoid major disruptions to traffic and pedestrians. After carefully removing the existing roof we installed a custom-manufactured, two-tone, green-glazed Ludowici tile with 20 oz copper gutters and flashings. The complex nature of this project included installing a vertical and horizontal batten system and a 5,000 square foot copper gutter system. The final effect is stunning.

    Industry Awards and Certificates
    Knickerbocker Roofing and Paving has won the prestigious National Roofing Contractors Association Gold Circle Award – one which recognizes workmanship excellence. Additionally (and closer to our Chicago region home) we’ve been repeatedly acknowledged by the Chicago Roofing Contractors Association, whose members include: contractors, manufacturers, distributors, manufacturer representatives, consultants and others industry professionals, who provide leadership for the industry in this region.

    Manufacturer Awards and Certificates
    For 2014, Knickerbocker received the Partner in Quality Award from Firestone Building Products. This award recognizes those contractors who meet requirements for installation excellence and performance of qualified materials within the roofing industry. We are extremely proud to be listed as a premier roofing contractor.

    Knickerbocker Roofing and Paving recently received the 2015 Firestone Building Products Master Contractor Award. Although this isn’t the first time we’ve received the recognition as a best roofing contractor, it is the most recent of the various awards we’ve received over the years. According to Tim Dunn, president of Firestone Building Products, “The annual Master Contractor Program recognizes our best contractor firms dedicated to installing roofing systems that help commercial buildings achieve long-term performance. We’re proud to have offered this award for the last 28 years to recognize our trusted contractor partners who are some of the best in the industry.” Other manufacturer awards and certificates that we’ve received include the “Ludowici Crown Installer” (Knickerbocker was one of only three companies to achieve this designation in the industry) as well as “Approved Carlisle Applicator of Sure-Seal Elastomeric Systems.” These are just two examples of the additional esteemed awards Knickerbocker has proudly accepted.

    Safety Awards and Recognition
    Our team takes safety extremely seriously and, as a direct result, we have been frequently recognized for our commitment to safety in what we do. A part of our safety program is the annual safety training program for all of our supervisors and field employees. We commonly share the company philosophy of “safety first.” In fact, many times over the years, our safety program has been recognized by organizations like the American Subcontractors Association (ASA –Chicago).
    Charity Awards and Recognition
    Last, but certainly not least, our company and employees have received awards and recognition by charity organizations for service to our local community. We’ve been honored for our contributions and service to the DuPage Habitat for Humanity, the Leukemia Research Foundation, and the cities of Harvey and Chicago, as well as other communities and organizations in the area.

    Check out the photo gallery on our website which includes a display of several of the many awards and certificates Knickerbocker Roofing and Paving has received over the years. We’re honored and proud to share our accomplishments with you and our community!

  59. Look Up! You’ll Find Examples of Our Work All Around the Chicago Area

    Leave a Comment

    It would take us hours, days, weeks, to tell you about all of the projects Knickerbocker Roofing and Paving has completed over the past 125+ years. So, for today’s blog we decided to save you the time and carefully selected a few of our favorite projects from recent years. Mind that if you’re ever in the Chicago area, you can simply “look up” and find examples of our work! Here’s a preview of what you’ll see:

    • Steep Slope Roofing at the Historic Monroe Building in Chicago
    Make sure to sneak a peek of the roof at the intersection of Michigan Avenue and Monroe Street in Chicago! Knickerbocker completed the roofing and gutter fabrication and installation job at this historic site, located at 104 S. Michigan Avenue. According to the building’s historical website, the Monroe Building “set a new benchmark for Chicago office space” when it was built more than a century ago. Specializing in projects such as steep slope roofing allowed us to complete the complex project. With Michigan Avenue and Monroe Street filled with local congestion, we used a cantilevered scaffold system that was erected 200 feet above the intersection. The project demanded capabilities beyond any standard roofing installation to meet the historic requirements for the job. This included removal of the existing roof and installation of a custom-manufactured, two-tone, green glazed Ludowici tile with 20oz copper gutters and flashings. The end results were, and still are, stunning. The Illinois Landmark Association awarded the Monroe Building project “Renovation of the Year.” You can take a look at all of the details of this project by visiting our website.

    • Architectural Sheet Metal at the Museum of Science and Industry
    At Knickerbocker, we offer roof and gutter fabrication and installation. You can see an in-person example of our architectural sheet metal fabrication at the Museum of Science and Industry (MSI, 5700 S. Lake Shore Drive, Chicago). The museum is a “hands-on” educational center with engineering exhibits and more. Before completing this project, MSI was in desperate need of a new roof. We shared the museum’s “hands-on” approach to work day-in and day-out on the installation. Replacements included a new in-laid gutter system that had to be coordinated with another contractor’s masonry repairs. Daily adjustments had to be made for precision and accuracy. Different size radius panels were required, and intricate soldering helped to secure water tightness on every seam of the roof. It was an intricate job, but everyone was happy with the end results! Read about this project on our website.

    • Low Slope Roofing at the River City Condominiums
    Located on the Chicago River in the “South Loop” neighborhood, the River City Condominiums were designed by Bertrand Goldberg as a “city within a city.” The distinctive “S” shaped building called for installation of new insulation, coverboard and Sarnafil’s EnergySmart PVC roof membrane and flashings. And it wasn’t just one, but 19 different and odd-shaped roofs belonging to the condominium community. This was a complex job, with material needing to be, at times, double-, triple- and even quadruple-handled with cranes, hoists and extra manpower to reach the different roof areas of the serpentine-shaped, multi-level building. Knickerbocker safely managed the complexity of the project, from start to finish. Learn more about this unique effort by reading further details on our website.

    • Green Roofing at the University of Chicago Medical Center
    We installed photovoltaic panels at the University of Chicago Medical Center, bringing the Medical Center all of the advantages of a green roofing installation. This project was a large, land-locked roof replacement with multiple levels, and was also logistically challenging. We staged the area with 7-story scaffolding, taking into consideration that the area also housed MRI equipment and other sensitive testing materials. After replacing the roof at the Medical Center, we installed 59 photovoltaic panels. You can find more details about our proud accomplishment here.

    • Roof Maintenance Services Throughout the Area
    We believe the best way to extend the life of your roof is to maintain it. Here at Knickerbocker we offer customized maintenance and service plans to fit our customers’ needs and budgets. The roofs we maintain are all over the area; Chicago, and other areas of Illinois, not to mention Northwest Indiana and Southeast Wisconsin. See examples of our work near and far!

  60. On the Sunny Side of the Roof: Solar Energy is Reaching New Heights

    Leave a Comment

    What is greater and more beneficial than the power of the sun? The effects of the sun provide needed warmth, boost productivity, and brighten moods; however, one of the most beneficial characteristics is the technological harvesting that can provide enough electricity to power entire homes and buildings. It’s truly remarkable.

    Up until recently, the full potential of its power as an energy source wasn’t completely realized. People knew it was possible and had successfully used the sun as an electrical resource, but there were cost prohibitions and other limitations.

    Today, solar energy is becoming universal, more economical, and as a result, communities around the world are taking serious note. According to this article, France recently mandated solar roofs for all new buildings in commercial areas, with the potential of “delivering a boost to installed solar capacity across the country,” coinciding with the provision of numerous environmental benefits.

    France isn’t the only place harnessing the sun’s power. It seems that Tesla plans to “reshape the power grid with millions of small power plants made of solar panels,” while other articles point to the way solar power is proving to be game-changing for utility companies. Why? Because now it is more prevalent and cost effective.

    As a result, homes, schools, office buildings, hospitals, and myriad commercial structures are installing solar rooftops at record levels. They are seeing the initial cost of installation quickly offset by the savings, as well as the marketing advantages a solar roof provides, happily looking to the sky for energy needs.

    While solar rooftops were originally thought of as only useful in areas of extreme sunlight, such as Arizona, the latest advancements and improvements mean it is possible and accessible to make good use of them anywhere. France, alone, speaks to this.

    Whether you are considering installing solar panels for a commercial, institutional or industrial building, there is one thing you need to know: you shouldn’t go at it alone. There are various factors, ranging from the size of the solar power system to the direction of the panels that can get complicated. Furthermore, rooftop work is dangerous and it is recommended to seek the help of professionals.

    If you are interested in turning your currently unused rooftop into a cost-saving and environmentally friendly energy resource, Knickerbocker can help. We will not only ensure you have a watertight and durable roof system, but we can install your energy generating solar system to make your experience and rooftop even brighter.

  61. Creating the Rooftop Garden of Your Dreams

    Leave a Comment

    There is currently a major trend that is taking place, not only nationally, but internationally, that is giving traditional landscaping a run for its money: rooftop gardens.

    From office buildings to senior living facilities, hotels to apartment complexes, and schools to sports stadiums, rooftop gardens are “sprouting” everywhere, and they are making outdoor living the latest craze.

    According to this Boston article, the Red Sox Fenway Farms feeds fans while providing numerous environmental benefits, including cleaner air. In Oakland, CA, Kaiser Roof Garden (featured here with other beautiful rooftops) is a car-park-meets-actual-park; complete with a lake, fountains, and bridges.

    So if you’re considering turning your unused roof into a land of greenery, you’re not alone, but there are some things to keep in mind:

    1. The primary purpose of your roof is to provide protection and keep moisture out of the building. Do not compromise the integrity of the roofing system when designing your green space.
    2. Not all structures can accommodate the added load from the soil, plants, pavers and other overburden. Involve a structural specialist to determine whether or not the existing structure can accommodate the added load.
    3. You will want your rooftop garden to last for many years, so give strong consideration to replacing your roof prior to installing a rooftop garden to ensure as many years as possible. Once the rooftop garden is installed, roof replacement will also require rooftop garden replacement.
    4. Down the road, any roof repairs will require disturbing the new rooftop garden. Prior to installing the rooftop garden, install an Electric Field Vector Mapping system which allows your roof repair team to quickly and accurately locate a breach in the roofing system while keeping any disturbing of the rooftop garden to a minimum.

    Before planning a rooftop garden, it is useful to note the difference between intensive and extensive roof gardens. Intensive gardens have greater depth and deeper soil, allowing for more variety, larger plants, and more features. As a result, they are more complex. These gardens have greater fertilizer and water needs, but can include many more features, including fountains, ponds, and more. As a general rule, intensive gardens have a planting medium of at least six inches.

    Alternatively, extensive roofs are up to six inches deep, feature less plant diversity, are simpler to install, and are generally better suited for smaller spaces where minimal maintenance is preferred. Either way, the result is an attractive use of previously unused space, offering countless opportunities for enjoyment.

    At Knickerbocker Roofing, we have extensive experience with installing rooftop gardens, supported by 125 years of roofing expertise. We install the new roof and all preparations (including EFVM, root barriers, drainage mats, insulation, membranes, etc.), and can install the garden itself.

    Whether you want an intensive or extensive roof garden, a 1,000-square-foot oasis or a 1,000,000-square-foot masterpiece, we can make any rooftop dream a reality.

  62. How, Why, and When to Make Safety a Priority

    Leave a Comment

    June means a lot of things to a lot of people: Father’s Day, baseball games, rising temperatures, and the beginning of backyard barbecue season, to name a few.

    Yet there’s one thing that we can all universally celebrate this June, and it’s something that affects everyone. June is National Safety Month, and it’s an important reminder to work, play, and live safely.

    Whatever your job – it’s extremely important to be aware of safety practices. When you work in building management or construction… it’s critical.

    According to a 2012 report by the Bureau of Labor Statistics, “construction accounted for the highest number of fatal work injuries of any industry sector.” Additional statistics in this report stated that fatal injuries in private construction increased by 5% in 2012.

    In any area of construction, workers and employers must emphasize safety. This, of course, means wearing all required safety gear, but also includes actively thinking about safety. It’s easy to get too comfortable and let certain practices go. This is exactly when accidents happen.

    In addition to remaining conscious of safe practices at all times, one way to ensure a safer workplace is to focus on individual aspects of safety throughout the month—i.e. scaffolding—and commit to ways of remaining safe within this area of focus. Another way is to make a checklist and follow it carefully.

    At Knickerbocker Roofing, we are highly concerned with worker safety; however, we realize that our industry is not always the safest, and as a result we encourage everyone to learn from the message of National Safety Month. Recent statistics have shown that roofing falls contributed to roughly one-third of all construction-related fall fatalities during the years of that specific study. To us, this underscores the importance of promoting this movement.

    No matter what you do exactly, or where you work, follow the message of the National Safety Council; make safety propriety in June, and every month thereafter.

  63. Energy Conservation Codes and Roofing: What You Need to Know

    Leave a Comment

    Most people know the important role that a roof serves to a home or building; it’s so much more than a simple covering. Of course the aesthetic appeal of a good roof adds immeasurable value, but beyond that, a good roof saves energy and money while making a building more efficient.

    What many people might not realize is that the energy efficiency of roofing is mandated by codes that require minimum thermal insulation levels. These codes are related to energy conservation and are increasing regularly. They vary individually by state and region, but follow the guidelines of the International Energy Conservation Code (IECC), which is determined by the U.S. Department of Energy.

    The purpose of increasing them, of course, is for buildings to continue achieving greater levels of energy efficiency, which is beneficial for a number of reasons. The DOE’s goal is a 30% improvement in energy efficiency compared to the previous version.

    The IECC is updated every three years and the current edition in effect for our area is IECC 2012. For the Chicago area, the latest edition increased the R-value requirements—the thermal resistance value of insulation—fromR20 to R25.

    Essentially, this means that existing roofs being renovated, and roofs that are built in new construction, must adhere to the latest R25 requirement. This pertains to all buildings, with the exception of detached one- and two-family dwelling and townhouses.

    While the specific codes that are followed are determined by individual states and cities—with some cities currently on the 2012 edition — it’s important to not only note that you must follow your city’s current requirements (again, R25 for Chicago), but to remember that these codes change regularly and rapidly.

    As each edition aims to improve efficiency over the last, we can safely assume that newer editions will increase the R-value for our city once again. While we don’t yet know what it will be, we do know that it will most likely increase, and it is important for building owners, builders, and maintenance staff to remain aware and current.

    At Knickerbocker Roofing, we are always on top of the latest news, changes, rules, and regulations related to roofing. If you have any questions about the IECC codes—or anything else—feel free to contact us anytime.

  64. It’s Always ‘Safety First!’ When We Provide Our Commercial and Industrial Roofing Services

    Leave a Comment

    Workplace safety is a hot topic in every industry these days – as it should be! Actually, proof that safety in industrial and commercial work has been a priority for several decades now was the formation of OSHA (the Occupational Safety and Health Administration – part of the U.S. Department of Labor) in 1970. Forty-five years ago, OSHA was created “to assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance,” according to the OSHA website.

    While OSHA sets an important standard in the industry, our safety standards meet and exceed those set by OSHA, and we continually enhance our safety program as we are committed to safety in everything we do. The biggest hazard in roofing is a fall hazard, so our number-one priority in terms of keeping workers safe is to implement strong fall protection measures. We train our workers to identify safety issues and mitigate those through the use of company supplied safety equipment and safe work practices. Our workers install safety rails and/or warning lines when the conditions allow to provide the greatest protection. When work is performed at a roof edge, our workers utilize safety monitors or wear safety harnesses and use lanyards for fall restraint and fall arrest.

    Highlights of our safety training include:
    • All new apprentices attend an OSHA 10-hour training class.
    • Our foremen meet on a quarterly-basis to discuss relevant safety topics
    • A third-party safety company performs random inspections and training at our job sites.
    • We provide annual safety training for all of our employees every spring

    These are just some of the measures we take to keep safety at the forefront of our operations. In fact, this year (like we do every year), we’ll be attending the Chicago Roofing Contractors Association Trade Show at the Drury Lane Conference Center in Oakbrook Terrace, January 22nd and 23rd. All of our foremen and superintendents will be attending the OSHA roofing safety presentation that will part of the CRCA conference.

    Safety comes first for us at Knickerbocker! We’re proud of our commitment and our employees’ commitment to safety. We work hard and follow our own strict safety guidelines, which meet – and often exceed – OSHA standards. At the end of the day, we just want to get everyone home safely.

  65. Business as Usual: How to Perform Roofing Repair without Disrupting Work

    Leave a Comment

    Most businesses don’t have the time or money to completely stop operations when work must be done on their building. Whether you’re a manufacturing facility, a school or hospital, a hotel, or a food processing plant, you can’t shut down because your roof needs repair or replacement. Yet you can’t ignore the roofing work that’s necessary.

    These challenges can seem like a catch 22—but there are solutions. First, let’s look at the most common challenges:

    • Vibrations: It’s not uncommon to find below-deck fireproofing, located underneath the structural roof deck. Vibrations from roofing equipment can cause this material to dislodge.
    • Tear-off debris: With tectum or gypsum deck, or concrete panels, it’s possible for debris to fall between the joints when work is being done on the roof.
    • Openings: When roof openings, i.e. skylights, are being removed or replaced, debris, materials, and/or hand tools can fall through these openings, causing potential safety hazards.
    • Joints and rust on metal decks: Debris and dust call fall through the joints of metal decks, and if the deck is rusted, there’s further potential for openings, through which debris can fall.

    Obviously, these situations can disrupt work within the building while posing serious safety issues—which is never acceptable. Noise from the work causes yet even more interruptions and annoyances. Furthermore, facilities such as hospitals cannot risk patient care and surgeries being disrupted, while food processing plants must remain free of any and all dust and debris.

    So what are you supposed to do?

    There are several ways to address these challenges and keep work flowing while maintaining safety:

    • Plastic protection: Roofing workers will cover sensitive items below with plastic.
    • Installing overhead protection: Protection placed above the facilities and below the roof deck will capture miscellaneous debris that might come through.
    • Coordinate schedules: Roofing work can be scheduled during off hours and at times when no one is working or present when and where the roofing work is being performed. Contractors will work around events at hotels, school and manufacturing hours, hospital schedules, etc.

    While every project is different in terms of work, schedules, and sensitivity, a quality roofing contractor—in addition to performing superior work on your roof—will know what solutions are best for these challenges, and will keep your work uninterrupted and your facilities safe.

  66. Can Your Older Roof Be Recovered?

    Leave a Comment

    Consider this scenario: you’re aware of the fact that your existing roof is aging and is in need of work. But the roof still seems to have some value. Therefore, you wonder whether the entire system needs replacement, or if there’s a less drastic option—one that can fix the older roof, without entirely replacing it.

    The short answer is yes, this is a possibility. There are circumstances in which a roof can be recovered, if the foundation of it is still in good condition.

    One possibility is the addition of an overlay—a full watertight roof system installed on top of a separation board, which separates the old system from the new one, allowing for a new, different type of roofing to be placed on top of it.

    A roof recovery of this type typically entails the installation of the separation board, a new membrane, and membrane flashings. Let’s explore this a little deeper:

    Separation Board: This is a board made of a traditional cover board material (i.e. gypsum or wood fiber) or added installation (i.e. isocyanurate), which adds greater thermal value. It is installed directly over the old roofing system.

    New Membrane: This can be any type of system (e.g. modified bitumen, built up roofing, PVC, TPO, EPDM), but it should match the needs of the existing building.

    Flashings: Due to their exposure to the elements—and where they sit, in areas of changes in elevation/direction— the flashings are typically the first area of failure in any roof system. Therefore, they are critical to the successful installation of an overlay. The new membranes should be adhered directly to the substrate, providing weather-tight conditions, which allow the roof to last for another 10-20 years. They are also the most challenging aspect of installation, underscoring the need for an experienced roofer.

    Of course there are several factors that determine specifics of the overlay installation, and things that must be kept in mind. Any ballast (e.g. river rock or gravel) must be removed prior to installation of the separation board. Additionally, overlays shouldn’t be installed where existing insulation may be wet. A thermal scan of the roof will identify potential areas of moisture, allowing the roofing professional to identify if any existing roofing and insulation needs to be replaced before installing the overlay. Finally, if an overlay has previously been installed, the existing roofing systems must be removed. Most municipalities limit the number of roofs installed on a structure to two.

    Clearly, there are factors that make roof recovery with an overlay challenging, but far from impossible. Experienced roofers can identify and overcome challenges—and in the end, can potentially save you from an entire roof replacement.

  67. Roofing Systems: What are They and How to Choose

    Leave a Comment

    In the construction or renovation of a commercial building, one question that always comes up among builders and contractors is “what type of roofing system should we use?” This, of course, is a valuable question, as the roof is an important part of any facility. In regards to commercial buildings, there are a variety of roofing options to choose from.

    Traditional Built Up Roof

    This type of roof has been around for over a hundred years; it consists of multiple plies of felt adhered in hot asphalt with gravel cast into a flood coat of asphalt on top of the system, which provides a protective barrier for the plies. The multiple plies provide redundancy within the roofing system. This type of system is now also installed with cold asphaltic-based adhesive in lieu of the hot asphalt to reduce odor during the installation process.

    Modified Bitumen Roof

    Similar to traditional built-up roof systems, modified bitumen roof systems provide redundancy with multiple plies installed. Unlike felt plies of traditional built up roofs, the modified bitumen material is made up of rubberized asphalt with reinforcing fabric embedded in the sheet. This provides for a thicker, more durable sheet. Granulated modified bitumen sheets also have small granules embedded on top that provides a protective layer for the membrane. Due to the durability of the modified bitumen plies, a flood coat and gravel are not necessary.

    Single-Ply Roof

    Single-ply roof systems have grown in the roofing market since the early 1980s. These are flexible sheets made up of compounded synthetic materials that are most commonly known as: EPDM, PVC, or TPO. When building these systems, the contractor typically lays the sheets down in adhesives and then heat welds or adheres the seams together where the sheets overlap. While the single-ply roof system does not have redundancy, it does feature durable membranes, which can typically be installed at lower cost than redundant roof systems.

    Liquid Based Membrane

    The liquid based membrane roof system is an emerging one that is beginning to gain some traction. These systems typically consist of an applied resin, an embedded fleece, and then encapsulating resin. The flexibility of the membrane allows it to accommodate the most challenging flashing details.

    So how does a contractor decide which roofing system to choose for a project? That decision comes down to a number of factors. First, how is the building used? The roof of a restaurant needs to consider that grease from the kitchen exhaust may impact the roof. A manufacturing plant may have chemicals or steam impact from the roof. A strip mall and apartment building have very different uses, but they both may have a large volume of small air conditioning units on the roof. All of these impact the decision of which roofing system to use. Second, where is the building located? The region of the country, and weather conditions, can impact which roof system is most appropriate. Third, what are the existing conditions of the building? Is there a roof garden, or a current roof that will be covered? Finally, the owner’s preferences obviously come into consideration.

    With any commercial building, the roofing system is an important piece of the puzzle. As you can see, there are a number of roofing systems to choose from, each dependent and more efficient with certain factors. With a roofing contractor like us, you can be assured that we will choose the right roofing system for your facility.

  68. Rebuilding Chicago’s Architectural and Cultural Heritage

    We are proud to announce that two recent projects we worked on have won Chicago Landmark Awards. According to the City of Chicago, these prestigious awards recognize companies whose work on landmark building has contributed to historic preservation, revitalization, and to investing in Chicago’s architectural and cultural heritage.

    Lorado Taft Midway Studios

    For the first project, at Lorado Taft Midway Studios, we removed and replaced their roofing (slate, asphalt shingles, and small low slope roofs) and sheet metal (copper and stainless steel flashings, gutters and downspouts), installed custom skylights, and rebuilt the cupola to replace the original. The roofing that was replaced on the main house part of the building was re-roofed in slate with copper sheet metal per original design. The remaining part of the building is a working studio where the custom skylights now allow artists to work with the benefit of the sun’s light.

    Indian Boundary Field House

    Another project that was recognized was the Indian Boundary Field House. After a fire damaged much of the building, we removed and replaced slate roofing (multi-color, multi-width, and rescinding slate roof), as well as the copper sheet metal flashings, valleys, gutters, and downspouts. Installation of multi-color rescinding slate is challenging and requires skilled tradesmen to install properly. This style of design utilizes large slate at the eaves with progressively smaller slate installed toward the top ridge.

    While both buildings were challenging to restore, we are always happy to have play a part in preserving Chicago’s landmark structures. Both buildings are now able to continue serving their original purpose while enhancing Chicago’s architectural and cultural heritage.

  69. Environmentally-Conscious Construction

    Leave a Comment

    In the building and construction industry, the past decade has seen an increase in environmental consciousness and the impact buildings have on our environment. As roofing experts with over 125 years of experience, we often get questions about the different programs and codes that apply to earth-conscious building.

    One of the most familiar and largest programs is LEED, or Leadership in Energy & Environmental Design. It is a government certification program that awards companies based on a points system and is focused on energy consumption. Typically LEED has applied to new construction, but it is not limited to this.

    There are five points rating systems, each with its own specifications, ranging from types of construction (retail, school, etc.) to specifics such as interior versus exterior. While the context of construction varies, the overall purpose is to reduce energy use and award those who are doing so.

    LEED has seen ups and downs over the years in its popularity and the importance placed on it, especially as new construction decreased significantly. However, whether it’s LEED or any other program, American companies are increasingly concerned with environmental impact, and that’s the most important thing.

    From a roofing perspective, there are plenty of ways the energy footprint can be reduced. For instance, using renewable resources, such as clay tile on steep roofs, can be seen as beneficial.

    Then there’s the longevity of a material; slate or tile roof, for instance, can last 80 years, and in general, if a roof lasts 25 years, rather than 10, it has less of an energy impact.

    Effective use of insulation reduces the impact on mechanical equipment and therefore saves energy. In warmer states, the use of reflectivity reduces the amount of work cooling equipment has to perform. Additionally, garden roofs might receive LEED points or would be considered beneficial by other programs, as they help limit the speed at which storm water goes into a drainage system.

    Finally, if we were to use roofing products made within 500 miles of our job site—for us, the Midwest—energy during transport is minimized.

    Whether it’s to get LEED points or comply with any other green codes, we are consistently aware of and focused on the environment, and we are happy to know that so are many other companies around the country.

  70. Our Work with La Rabida Children’s Hospital

    Leave a Comment

    As roofing professionals, we are consistently working on new and complex projects in the Chicago area. Recently, we completed work on the new outpatient clinic at La Rabida Children’s Hospital, located adjacent to Lake Michigan. The hospital was not only looking to build an addition to the current facility, but also to renovate some existing buildings. This is where Knickerbocker stepped in.

    Specifically, we installed new PVC roof systems to meet current codes, as well as provide proper insulation and reflectivity to the building. On both the new construction and the existing construction, we installed a 60 mil Johns Manville white PVC roof membrane adhered to 1/2 ” Securock cover board. The new construction features a metal deck substrate, and the existing building features a concrete deck substrate.

    The project also called for a green roof to be installed on the new building to align the facility with the city’s vision to become more sustainable. We installed the garden roof and will maintain it for its first two years. Here, we also put stainless steel counterflashing throughout the 13,600 square foot roof.

    While it was a challenge to balance and configure the green roof on time in order to meet the proper timeframe for planting and aligning it with the construction occurring on the current building, we are proud to say we completed both projects on schedule. It was exciting for us to work on a large-scale project that allowed us to perform multiple installations while meeting excessive deadlines.
