Duro-Last® has been the industry leader in producing custom-fabricated single-ply roofing systems, designing each roof to fit building specifications exactly, and manufacturing it under controlled factory conditions. Duro-Last's custom fabrication of single-ply roofing systems offers several advantages:

  • Duro-Last® prefabrication eliminates up to 85% of on-site, rooftop membrane seaming.
  • Prefabricated roofing systems are easier to install throughout the year, even during adverse weather conditions.
  • Single-ply roofing prefabrication dramatically reduces waste, both during the manufacturing process and installation.
  • Panel sizes, shapes and colors can be pre-planned and prefabricated to achieve desired visual results.

The Duro-Last Single-Ply Roof Membrane

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.
