What Is a Built-Up Roofing System?


Built-up roofing can be used on low-slope roofs. It is composed of layers of bitumen, reinforcing fabrics, and reinforcement fabric. BUR (built-up roofing) is the preferred option for flat roofs, as it creates a sealed surface.

Types Of BUR Roofing

BUR roofing typically consists of ply sheets and bitumen, with at least one surfacing. Bitumen can be either hot or cold. It will need to be heated if it is hot before it can be installed. The adhesive property of cold bitumen is that it does not need to be heated.

Special types of fabric called ply sheets can be reinforced with fiberglass or organic materials. Each ply sheet can be laid on top of hot or cold bitumen. Surfacing materials can be made of fine gravel or stone. Surfacing materials give a finished look.

Ballasted roofing can be described as a type of built-up roofing. The roof structure is not held or fastened to the lower layers. The roofing will stay in place by the surface layer.
