Built-Up Roofing Systems, also known as BUR, are considered one of oldest and most reliable roofing systems for commercial properties that have a low sloping or flat structure.
BUR roofing systems are composed of three elements: felt, bitumen, and surfacing. The felt material, composed of glass, organic or polyester fibers, is designed to serve the same purpose as reinforcing steel in concrete, acting as tensile reinforcement to resist the extreme pulling forces in the roofing material. When installed in layer fashion, felt materials also permit more bitumen to be applied to the entire system. Bitumen, consisting of either coal-tar or asphalt, is the adhesive that holds the felt materials together as well as serving as the waterproofing material in the system. Typical surfacing materials that are normally applied to BUR include smooth asphalt, gravel, slag, or a mineral-coated cap sheet.
With a track record that is over 150 years old, BUR provides a thick, durable roof covering, may be used in a broad range of building waterproofing applications, and may be maintained and repaired for extended life after many years, unlike other roofing systems, which require replacement. Built-Up Roofing Systems have consistently maintained an excellent reputation in the commercial roofing industry, with building owners, architects, engineers, roofing product manufacturers and commercial roofing contractors. While the initial cost of a BUR system may be greater than other low-slope applications, Built-Up Roofing Systems prove to be well worth the investment in the long-run.
