Features

  • 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 or coal tars) 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.

    Benefits

    • BUR surfacing materials can be coated to reduce UV radiation.

    • These coating provide the additional benefit of protecting the roof system from premature aging as well as reducing building interior cooling and heating cost
