BUR Roofing

Built-Up Roofing (BUR) is one of the oldest and most durable systems available.
Its multiple layers provide extra protection and perform well in extreme weather conditions.
Built-Up Roofing Systems consist of three components:

Bitumen asphalt provides the water proofing and adhesion.
Reinforcement with Ply Sheets (felts) provides tear strength, puncture resistance, multiple layers of waterproofing, span caps in the substrate and improve fire ratings.
Layers or plies of roofing felts are laid between asphalt or bitumen. The surface of the roof can have a gravel application, or a mineral cap sheet.
