About Duro-Last

Duro-Last is The “World’s Best Roof”®

Duro-Last’s custom-prefabricated, reinforced, PVC roofing system is ideal for any flat or low-sloped application. Extremely durable and easily installed by authorized contractors, the Duro-Last single-ply roofing system is also leak-proof and virtually maintenance-free. Over two billion square feet of the Duro-Last PVC roofing system membrane have been installed on all types of commercial, industrial, and institutional buildings throughout North America.


Every Duro-Last single-ply roof is measured and manufactured to exact size, accommodating every rooftop penetration. Prefabricating the vinyl roof membrane in our controlled factory environment eliminates up to 85% of on-site seaming, and improves the long-term performance of the roofing system. This precise attention to detail ensures an excellent fit, eliminates waste, and delivers worry-free, leak-proof protection.


The Duro-Last roofing system, made from a PVC membrane, is resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes. Duro-Last’s custom flashing components – made from the same vinyl roof membrane as our deck material – resist ponding water and help prevent roof problems.

Installed With No Disruptions

There are no loud machines, hazardous materials, noxious fumes, or messes involved in installation, meaning building occupants will barely notice a new roof is being applied. The Duro-Last roofing system comes with all accessories included and mechanical and welding components ready-to-install, allowing a watertight, monolithic installation.


As a proud charter partner in the EPA’s ENERGY STAR® Roof Products Program, Duro-Last is a leader in cool and sustainable roofing solutions. Of the white, single-ply products rated by the ENERGY STAR roof products testing criteria, only the our Cool Zone®  roofing system has retained reflectivity of greater than 85% after three years of weathering. This high sustained reflectivity is saving significant energy and money for building owners all over the United States.

Backed By The Industry’s Best Warranties

Duro-Last offers the best warranties in the industry to protect commercial and industrial installations, including a 20-year warranty and our standard, comprehensive 15-year full warranty, which is transferable, has no exclusions for ponding water, and provides coverage against consequential damages that result from defects in the Duro-Last PVC material.
