Built-up Roofing Membrane

Built-Up Roofing Membrane, commonly known as BUR, is composed of alternating layers of bitumen and reinforcing fabrics that create a finished membrane. This material is basically a tar-and-gravel roof which has been used in the U.S. for over 100 years. The number of layers that it’s built with can be adjusted to control costs and meet durability requirements. Additionally, a BUR system inherently incorporates insulation properties in the design because of the multiple layers, which can boost the energy efficiency of the overall roofing system. BUR is one of the most cost-effective and rugged roofing types available for low slope roofs.
