Commercial Roof – Built-Up/Torch/Modified Systems
At Florida Quality Roofing we are your commercial roof experts with a keen understanding of the importance of finding the right roofing system for your project. Let us guide you in the process of selecting your commercial roof system.
Built-Up (BUR) Commercial Roof
Built-Up Roof commercial roof systems consist of multiple layers of felts, fabrics or mats that are saturated with bitumen, either asphalt or coal tar pitch. The surface of the roof can have a gravel application, a mineral cap sheet or a weather resistant coating to help protect the bitumen and felts from premature weathering.
BUR is one of the oldest low-slope systems that are still applied to commercial roofs today. BUR’s 120 year track record is unsurpassed in the roofing industry and continues to offer building owners dependable service.
Florida Quality Roofing can review the performance characteristics associated with the various Modified Bitumen and Built-Up Roof systems so the right roof system can be selected based upon the conditions associated with your individual commercial building.
Modified Bitumen Commercial Roof
Composed of asphalt and reinforced with either polyester or fiberglass, modified bitumen roofs are a blend of traditional and modern roofing technologies. Two different polymers, Styrene Butadiene Styrene (SBS) or Atactic Polypropylene (APP), are used to modify the membrane and impart greater elasticity and temperature flexibility. Since polyester fiberglass fortifies the roof system, it exhibits more strength and resistance to punctures and is typically installed in various layers to provide a multi-tier protection system from water, extreme temperatures and wind uplift.
