Modified Bitumen (MB) roofing is an asphalt-based, close counterpart of the Built-up-Roof (BUR) designed for buildings with flat roof structures. Improved resistance to fragility at cold temperatures, better flow resistance at high temperatures, and improved elasticity can be achieved by blending synthetic rubberized polymers with asphalt in lieu of modification by the blowing process used for BUR asphalt. There are numerous surfacing options for this system which include a factory applied mineral surface, gravel surface, including “cool roof” coatings which are highly-reflective to save on building cooling costs.


MB may be installed by the torch-application method, or “hot-mopped” like BUR, or applied with “cold-process” adhesives.
