Commercial Products

A reliable commercial roofing system offers your business strong protection against weather damage to furniture, expensive equipment and important documentation. That is why A+ Roofing specializes in installing only top-quality commercial roofing products by leading manufacturers including GAF, Johns Manville, Firestone, CertainTeed, Owens Corning and IKO. We provide roofing products, repair and replacement for both steep-slope and low-slope commercial buildings.

Low-Slope Roofing Products

Most commercial buildings feature a “flat” or low-slope roof, meaning the pitch of the roof vertically rises between two and four feet in a horizontal line 12 feet across. (Every roof should have at least a slight slope to drain.) Because of the low slope, this type of roof does not drain as quickly as steeper roofs – a characteristic that makes them more susceptible to leaks and water backup due to ice dams. For this reason, low-slope roofs require different roofing systems than steep-slope structures, such as:

• TPO, a single-ply thermoplastic roofing membrane that features heat-welded seams for integrity. TPO is often manufactured with high surface reflectivity for greater energy savings.
• PVC, or polyvinyl chloride, offers easy installation and heat-welded seams that make it an economical, long-lasting roof for a variety of commercial applications.
• EPDM, a rubber-based single-ply roofing membrane, is the original single-ply roofing system. It is durable and affordable, with seams that are treated with adhesive.
• Modified bitumen, a common low-slope roofing material, is asphalt-based and produced in rolls. It can be heat-applied or adhered to the roof surface for strong weatherproofing.
• Built-up roofing (BUR). Another low-slope system with a long performance history, BUR includes multiple layers of tar paper with are covered with hot asphalt to “build up” a watertight cover. The surface is then covered with gravel and more hot asphalt.

Steep-Slope Roofing Products

Like most residential roofs, commercial steep-slope roofs have a pitch above 2:12, which means they rise more than two feet for every 12 feet in horizontal length. Steep-slope roofing generally lasts longer than low-slope roofing because water drains much more efficiently and the material is subject to fewer direct UV rays. The following materials can be considered for commercial steep-slope applications.

• Architectural & dimensional shingles
• Slate & tile
• Wood shake
• Low-maintenance protection
