  1. 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.

  2. Go Green…with a Garden Roof

    Gardens and roofs. Have you ever thought of putting the two together? In current years, garden roofs have become extremely popular, especially in larger cities such as Chicago, and buildings have seen much value in them. Recently, there has been a lot of political support for garden roofs here in Chicago—due to the positive environmental benefits—and many of the larger buildings in downtown Chicago feature these garden roofs. As installers of these roofs, we understand the benefits and values of garden roofs, as well as the importance of having skilled contractors constructing these roofing systems on industrial, commercial, and institutional buildings.

    What are some of the benefits of having a garden on your roof? It’s a “green” initiative, meaning it has a positive environmental impact. Since the gardens help to protect the roof from the sun, the thermal impact on the roofing system is reduced and the roof’s viability is extended. Additionally, the garden roofs help to retain storm water, which is much needed when storms hit—the gardens hold onto the water longer, allowing the excess water to be put into the systems more slowly. The result? City sewer systems are impacted less by large storms.

    How do you make sure your building is a candidate for a garden roof? Typically, a garden should only be installed on a newer roofing system, and it should use light-weight materials, so that the load on the roofing structure is not severely impacted. The integrity of the roof is the most important factor. It is essential that you employ a skilled professional roofing contractor, as opposed to landscapers; roofing contractors know that the garden component is not the entire roof—they understand the various layers and logistics required in constructing these waterproof roofs.

    As roofing contractors in Chicago, we have installed a number of garden roofs throughout the city. For more information on garden roofing systems, see the CRCA’s video (we are mentioned at the end!).
