Modified Bitumen

Modified Bitumen (MB) roofing is composed of asphalt with additional chemicals designed to give it rubbery or plastic properties. These membranes originated in Europe in the 1960s and have been in use in the United States and Canada since the 1970s.

Applications for Modified Bitumen Roofing

Modified Bitumen roof systems have been used in both commercial and industrial applications and have proven long-term viability. By blending Modified Bitumen with chemicals such as Styrene Butadiene Styrene (SBS) and Atactic Polypropylene (APP) you can create increased resistance to cold, more elasticity and better flow resistance at hotter temperatures. APP modified roofing is torch applied, SBS modified roofing can be torch applied, hot asphalt applied or cold applied.

Modified Bitumen roofing comes rolled, and the characteristics it will exhibit can be altered by the surfaces it is rolled onto. There are a variety of surfacing options for the material, including a smooth surface, mineral options like river rock, metal options like copper or asphalt set with gravel. MB can also be used as part of a hybrid system by using other roof materials to build up the substrate layers.
