Duro-Last The World’s Coolest Roof!

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 membrane is available in white, tan, gray, or dark gray.

Prefabricated and Installed by Authorized Professionals

Every Duro-Last roof is measured and manufactured to exact size, accommodating every roof top penetration. Prefabricating the roof in the Duro-Last factory environment eliminates up to 85% of seaming that is done on-site during roof top installation, and 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. Duro-Last can even assist your architect, facilities or maintenance personnel in developing specifications for your roofing project.

The Duro-Last Commercial Roof System can only be installed by authorized Duro-Last contractors who have received extensive training in this system. Parsons Roofing is the number 1 Duro-Last roofing provider in the world.
