MODIFIED BITUMEN

Modified Bitumen (MB) roofing is an asphalt-based, close cousin of the Built-up-Roof (BUR) designed for buildings with low-slope or “flat” roof structures. With its exceptional durability, Modified Bitumen is a reliable product in both new construction and roof replacement markets. Increasingly, more facility managers and specifiers are opting for the safety of the cold process applied systems in lieu of an open flame around flammable materials. Modified Bitumen roofs give designers and installers an even broader array of options than BUR. MB may be installed by the torch-application method, or “hot-mopped” like BUR, or applied with “cold-process” adhesives.
