The Duro-Last® Roofing System is a custom-prefabricated, reinforced, thermoplastic PVC single-ply roofing system that is ideal for any flat or low-sloped application. It’s tough, energy-efficient, resistant to chemicals, fire and high winds, and virtually maintenance-free.
Extremely durable, over a billion square feet of Duro-Last® membrane has been installed on all types of commercial and industrial buildings throughout North America. All commercial Duro-Last® installations receive a factory inspection and the “world’s best roofing” warranty
The “Made-to-Order” Prefabricated Roofing System
For low-slope roof applications, Commonwealth Roofing features “The World’s Best Roof” from Duro-Last®. We are one of the area’s few Duro-Last® Elite Master Contractors and have installed over 3 million square feet of Duro-Last®.
Prefabricated
Prefabricating the roof in a controlled factory environment eliminates up to 85% of the labor-intensive seaming that is typically done on-site during other roof top installation. This improves the long-term performance of the roofing system. This precise attention to detail ensures an excellent fit and delivers worry-free, leak-proof protection.

Durable
The Duro-Last® roofing system is resistant to fire, chemicals, grease, high winds & punctures, resists ponding water & easily accommodates wide temperature extremes. Duro-Last® custom flashings seal up the weak points in the roof system & help solve roof problems before they can occur.
Installed with No Disruptions
Building occupants will hardly know a new roof is being applied, because installation is relatively quiet, fast, and safe. There are no loud machines, no hazardous materials, no noxious fumes, no hot tar & no mess. In most cases, a new Duro-Last® roofing system can be installed over an existing roof without an expensive messy tear-off.
Energy-Efficient
Duro-Last® has introduced the Duro-Last® Cool Zone® brand to address the growing nationwide interest in energy efficient roofing systems & is proud to be a “charter partner” in the ENERGY STAR® Roof Products Program, sponsored by the U.S. Environmental Protection Agency.
The Industry’s Best Warranties
Duro-Last® protects commercial & industrial buildings with a comprehensive inspection & 15-year full warranty that provides maximum protection with no exclusion for ponding water.
Commonwealth Roofing can help you decide which Duro-Last product will best meet your needs.
