Bulit Up Roofing Systems

A type of flat roofing system, a built up roofing (BUR) system is installed by setting multiple layers of asphalt or coal tar saturated felts or fiberglass mat roofing plies. The alternating layers include an insulation board, base sheet, hot- or cold-applied felts, surfacing materials and flashing materials.

If properly installed with quality bitumen, felts and flashings, BUR systems can be quite resilient.  In fact, depending on the materials used and with proper maintenance, built up roofing systems can last up to 30 years. Still, built up roofing systems are not flexible, meaning they cannot be installed on every type of structure.  BUR systems are mainly used on roof decks with minimal movement or where proper expansion joints are used.
