Article Summary: 

The most common types of commercial or industrial flat roofs available for commercial or industrial properties in the Greater Toronto Area are Built-Up Roof (BUR), EPDM (Rubber Membrane), Modified Bitumen (MBT) and Modified Asphalt (MAT). BUR roofing is a traditional type of flat roof made from hot tar, asphalt and gravel, while EPDM (Rubber Membrane) is a synthetic rubber created from ethylene propylene and diene, resulting in a highly flexible, yet durable flat roof. Modified Asphalt (MAT) is a common type of flat roof designed for flat and low-sloped buildings and is composed of polymer modified bitumen material and reinforced with one or more layers of fabric. Commercial or industrial flat roofs can be installed with a variety of application methods, including cold applied, heat weld, self-adhered, mechanically fastened, and hot applied. There are two types of modified bitumen membrane used for commercial or industrial flat roofs: Atactic Polypropylene (APP) and Styrene Butadiene Styrene (SBS).

PVC or TPO are single layered and made from material that is either white or gray. Both PVC and TPO roofs are becoming increasingly popular due to their environmental benefits.
