Built-Up Roofing Systems

Built-up roofing (BUR) is a continuous, semi-flexible roof membrane consisting of multiple plies of saturated felts, coated felts, fabrics, or mats assembled in place with alternate layers of bitumen. BUR can be surfaced with mineral aggregate, bituminous materials, a liquid-applied coating or a granule-surfaced cap sheet. BUR helps to reduce installation costs while tackling the most demanding roof applications.
