Company Profile:
Duro-Last Roofing, Inc. manufactures a custom prefabricated, reinforced, thermoplastic single ply roofing system that is ideal for flat or low-sloped application. Extremely durable and easily installed by authorized contractors without disruption to daily operations, the Duro-Last roofing system also is leak proof, resistant to chemicals, fire and high winds, and virtually maintenance free.

The Duro-Last® Cool Zone roofing system utilizes an ENERGY STAR® labeled membrane that reflects up to 87% of the sun’s energy – delivering real cost savings for building owners and managers. The Cool Zone system also can help in obtaining credits toward LEED certification.

For buildings with aging metal roofs, the prefabricated, single ply Duro-Shield® metal retrofit system can be installed over an existing roof without an expensive tear-off. Because the Duro-Shield system is a flexible membrane, it expands and contracts with the weather, virtually eliminating the risk of rooftop leaks.
