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. It provides an exceptional balance of quick installation, strong durability, and a variety of styles and appearances. Engineered modified bitumen roofing membranes originated in Europe in the mid-1960′s and have been used successfully in the United States and Canada since the 1970′s.

O’Donnell Roofing MB solutions provide superior waterproofing capabilities that include high strength, durability, and a proven track record of performance all within a competitive life cycle cost structure.
