Modified Bitumen Roofs

Modified Bitumen Roofs

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 fortify 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.
