What is Modified Bitumen Roofing?
Modified bitumen is thought of as the evolutionary cousin of the built-up roofing systems (BUR) that have been used on low-slope roofs for more than 100 years. It is made of asphalt combined with polymerized rubber or plastic, then reinforced with fiberglass to create a rugged-yet-flexible waterproof membrane.
Benefit of Modified Bitumen
Modified bitumen roofing is primarily used on flat or low-sloped commercial roofs. Depending on the type and material, these membranes may be installed as part of a two-layer system or as part of a multi-ply system.
