Steep-Slope Roofing Services

Commercial and institutional building codes define a steep-slope roof as any roofing system with a 3:12 or greater pitch. This means the roof rises three inches (or more) across a 12 in. length, and has a 14-degree or greater slope. The steeper the roof’s slope, the better it can shed water and snow after a storm, and this further reduces the loading on the roof and the likelihood of damage from leaks and ice dams.

Common materials used for steep-slope roofing systems include:

• Asphalt shingles.
• Clay tiles.
• Metal roofing.
• Slate.
• Wood shakes.

Knickerbocker Roofing works with all of these materials to upgrade, replace, and repair steep-slope roofs. In particular, asphalt shingles are the most popular option for commercial and institutional steep-slope roofs. This material is cost-effective, easy to work with, and easy to repair. Asphalt shingles are also very versatile and can be used on a wide variety of roof shapes.

This is a key advantage of steep-slope roofing systems. Conventional flat-roof systems can allow water and snow to pool or pile up on the surface, and this significantly increases the risk of leaks, water damage, and excess weight on the roof. A sloped roof sheds water so there are no standing puddles or piles of snow. Instead, water and debris slide down the incline and toward gutters and downspouts.

Water shedding can dramatically extend the lifespan of a roof by preventing potential leaks, minimizing wear on materials, and keeping weight off the roof. By eliminating common sources of damage and structural stress, a steep slope helps a roof last longer with fewer repairs and associated expenses.

Most residential, commercial, and institutional buildings can benefit from steep-slope roofs. They’re most beneficial for buildings that visually integrate the aesthetics of the sloped roof, as well as buildings in areas where heavy rainwater and snowfall may pose a threat to flat roofs. They’re commonly used on residential buildings, multi-family housing properties, and townhomes. They’re also becoming more popular on a growing number of commercial structures, including churches, hotels, cozy restaurants, and historic buildings.
