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 exceptionally 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, high strength and durability, a proven track record of performance all within a competitive life cycle cost structure.
