Low Slope Roofing Systems

Industrial Hall Flat RoofingWhen Universal Roofing approaches low-slope roofs, we look at the whole system versus just the materials. The roof system is defined as the membrane and the roof insulation. Low-slope roof assemblies are comprised of three components: the membrane, insulation, and the deck. The assembly is defined as the deck, along with the roof membrane and roof insulation. Low-slope roofs are commonly referred to as flat roofs. Roof systems with a pitch less than 3:12 are considered low-slope roofs.


External Commercial Roofing
Ethylene propylene diene monomer roofing, EPDM, is an extremely durable synthetic rubber roofing membrane that is widely used in low-slope buildings in Indianapolis and the surrounding counties. It is well regarded for its weathering ability through a wide range of conditions throughout the years.

Built-up Roofs (BUR)

Flat Roof Gravel
Built up roof membranes, BUR, have been one of the most popular low slope roofing systems used over the last 100 years in the US. BUR systems are generally composed of alternating layers which created a reinforced finished membrane (containing layers of bitumen and fabrics). Built up roofs are generally impenetrable to water based on their “four plies” or layering installation. This makes a Built up roof an obvious choice for a midwestern commercial property with a variety of weather conditions.
