Modified Bitumen roofs are roofing assemblies formed with modified bituminous membranes.
The modified bitumen roofing system is a hybrid built-up roof. It has the benefits of the built in redundancy of the BUR, along with the added strength, flexibility and UV resistance of a modified membrane.
Modified Bitumen or "modbit" membranes consist of an asphalt and polymer blend which allow the asphalt to take on characteristics of the polymer. There are several surfacing option for this system which include a factory applied mineral surface, a gravel surface laid in bitumen or a liquid applied coating that is typically reflective in nature.
