What is Duro-Last?

The Duro-Last vinyl roof membrane is a proprietary thermoplastic formulation consisting of PVC resins, plasticizers, stabilizers, biocides, flame retardants and U.V. absorbents. A weft-insertion knitted scrim that is laminated between two layers of PVC film gives the membrane its strength and durability. The Duro-Last single-ply membrane is available in white, gray, dark gray, tan, or terra cotta.

Duro-Last ROI:

  • Save up to 40% annually on your electric bills
  • Improve insulation performance by 25%-30%

Installation requires no loud machinery, no hazardous materials, no noxious fumes, and no mess, so no disruption to your business!

The Duro-Last Roofing System can typically be installed over the existing roof, saving you approximately $12,000, the average cost of tearing off the old roof. It can also be installed in the heat or the cold. You get a lasting solution that is hassle-free and delivers the most ROI.
