MODIFIED BITUMEN ROOFING MEMBRANES

Modified Bitumen Roofing membranes are chemically modified. Chemicals called polymers are added to the bitumen, changing the chemistry of the bitumen. The surfacing used on modified bitumen sheets can be foil, mineral granules or coatings. These sheets are often used as flashing material for built up roofing systems.

Generic Modified Bitumen asphalt membranes are typically mineral based surface sheets of polymer-modified asphalt. The polymer is SBS but there is no minimum percentage of polymer (making it difficult to know exactly what you are getting). Polymer percentage is important for puncture and fatigue resistance. Generic modified bitumen roofing membranes are typically reinforced with polyester that is not dimensional stable leading to shrinkage and expansion and contraction of the polymer.

High Performance Modifieds contain a high percentage of sophisticated polymers and a high strength reinforcing structure that is dimensionally stable. The polymers provide the weathering and UV resistance and are designed to resist puncture and handle fatigue. The reinforcement has the responsibility of resisting tear, providing puncture resistance, and the tensile qualities that have been the key to roofing success for more than 100 years.
