You may wonder about your commercial roofing system as a commercial building owner. Do you need to perform maintenance? What are the different types of roofs on commercial buildings?
What’s the difference between PVC and TPO? Because commercial roofs are so different from residential roofing, you need the experience of a commercial roofer for your commercial buildings.
An expert from the commercial roofing service by Douglas Construction in Atlanta describes the differences in types of roofs on commercial buildings below.
Modified bitumen is an asphalt membrane roof that seals a roof against weather, including wind, rain, and hail. The asphalt material includes plastic or rubber polymers and reinforcement from fiberglass to improve flexibility.
Perfect for flat or low-slope roofs, modified bitumen usually includes a base sheet and a cap sheet, but many customers opt for a three-layer installation.

This single-ply membrane roof is actually a rubber membrane roof. Application to any roof surface is simple, and the white material reflects heat from the sun.

Typically the most expensive choice for single-ply membrane roofs, PVC roofs include three layers of material. Installers attach the substrate with adhesive, often mechanically attaching the edges for security against strong winds. The middle layer adds a supportive polyester material, then the top layer offers amazing leak protection with heat-welding of the seams.

This rolled synthetic rubber roofing often includes recycled tires, slate dust, and sawdust. It is one of the most affordable types of roofs on commercial buildings. With proper care, these roofs can last up to 60 years. Although not as durable as PVC, repairs to an EPDM roof are easy and affordable.

Cons:
Built-up roofing (BUR) utilizes layers of asphalt or bitumen alternating with roofing felt, often with a top layer of gravel or another aggregate on flat roofs. The built-up roofing system has been in use for over 100 years on commercial buildings.
