Single-Ply Membrane Roofing Systems, or more commonly known as TPO roofing systems, are popular because of its white color and corresponding reflective properties.

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. Engineered modified bitumen roofing membranes have been used successfully in the United States and Canada since approximately 1975.

Built up roofs has long been the standard in low sloped roofing applications. The simplistic layer design gives this unique membrane outstanding water and weathering resistance. According to the National Roofing Contractors Association, BUR Membranes have been used in the U.S. roofing industry for more than 100 years. Generally known as “tar and gravel” roofs, BUR membranes have been a time-tested and trusted choice for simple flat-roofing.
