Built-Up Roofing

Built-Up Roofing (BUR) is one of the oldest low-slope roofing systems that is applied to commercial roofs today.
It's 120 year track record is unsurpassed in the roofing industry, having continued to provide commercial property owners with dependable services.

Built-Up Roofing systems are composed of either asphalt or coal tar pitch and are assembled on the rooftop. Fibrous glass or organic rag felts are used in the installation. After the felts have been installed, a surfacing material such as slag or gravel aggregates are set into place. Surfacing materials protect the membranes and also help protect the roof from UV degradation. In addition, a smooth surface asphalt BUR system can be coated with aluminium paint or white reflective materials to further help fight against the effects of UV and cut down on cooling costs.
