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. The granule coating offers UV protection.
