Built-Up Roofing

Built-up roofs (BUR) are generally known as tar and gravel roofs. They are composed of layers of asphalt and roofing felt, assembled in layers that form the finished roofing membrane.

Modified Bitumen

A modified bitumen roofing system is composed primarily of polymer-modified bitumen reinforced with one or more plies of fabric such as polyester, fibreglass or a combination of both. Factory surfacing is composed of mineral granules. The bitumen provides primary waterproofing protection, while the reinforcement adds strength, puncture resistance and overall system integrity.
