Modified Bitumen Roofing Systems

With a choice of cold or hot applied and a range of performance levels, all of which provide exceptional waterproofing protection for your building, Tremco Roofing's POWERply® line of modified bitumen (MB) roofing solutions combine the advantages of advanced adhesives and membranes with the time-tested, reliable installation techniques of conventional built-up roofing to provide a fully integrated, long lasting- roofing system. Tremco’s MB system, POWERply Endure®, couples a new generation of MB membranes with the POWERply Endure BIO Adhesive TF (a USDA Biopreferred product). The membranes feature GranuLock™, a unique surface treatment that reduces granule loss to practically zero; an extremely durable bitumen blend; anti-wick fabric; and a RooF-ID™ chip embedded in each roll enabling the membrane to be identified after installation. Combining them with the fast-curing, cold process, virtually odorless POWERply Endure BIO Adhesive TF creates a roofing system of exceptional quality and toughness, designed to withstand the toughest weather.

POWERply roof membranes offer the best granule adhesion in the roofing industry. It gets this reputation with its colors, standard white or ultra- white, that are used for Energy Code compliance. To add on to its durability, its fire rated surfacing provides for the safety of those inside the building.

POWERply MB membranes are constructed using specialized fabrics selected for their unique features and benefits. Several POWERply brands are based on fiberglass reinforcing mats, which offer strength and long term stability to the finished roof membrane. Other POWERply brands are manufactured using polyester, which provides puncture resistance along with an exceptional mix of tensile and elongation which exceed industry specifications for roof system performance. The top performing POWERply membranes utilize an engineered combination of fiberglass and polyester, which combines the performance advantages of both fabrics to provide the best long term roof membrane performance with the capability of extending its service life with the application of fluid applied restoration systems in the years to come.

The POWERply system is best when fully adhered with Tremco POWERply Endure BIO Adhesive, which is Tremco’s cold applied, ultra-low odor, solvent- free, fast curing, watertight membrane adhesive. POWERply membranes may also be applied with traditional hot applied bituminous adhesives, such as Tremco THERMastic SEBS Modified Asphalt. These membrane adhesives enable POWERply roof systems to resist the uplift pressures generated during exposure to high winds.
