WASHINGTON, D.C. — The Asphalt Roofing Manufacturers Association (ARMA) has updated the Modified Bitumen Design Guide, a valuable resource for building owners and roofing professionals working with asphaltic roofing systems.
The collaborative guide is broken up into sections and addresses relevant aspects, issues and concerns of modified bitumen roofing systems and its associated components, substrates, construction techniques and innovative uses. It includes considerations for latest trends in roofing that call for the roof to provide more than waterproofing, including solar, garden and recreational surfaces.
