Duro-Last membrane is printed with either a ballast or shingle print, and the Duro-Last Vinyl Rib Roofing System offers the architectural appearance of a standing seam metal roof. All of these systems provide an aesthetic look, plus the watertight performance and long-term durability of the Duro-Last Roofing System.

Has time caught up with your metal roof? Duro-Last Metal Retrofit is the solution! Avoid replacing your metal roofing by covering the roof with PVC singly-ply membrane. While metal roofs can offer lower initial installation costs and protection against fire, installing a Duro-Last single-ply membrane over your metal roof means:

• No more seam and fastener problems.
• No more cracks and leaks around penetrations
• No more rust and corrosion

Benefits

• The Custom-Fabrication Advantage: Through Duro-Last’s custom-fabricated retrofit roofing systems – which can include both membrane and accessories – up to 85% of the seams can be completed in a factory-controlled environment. This eliminates most of the on-site fabrication that can lead to roof leaks.
• Energy-Efficient: By reflecting up to 88% of the sun’s energy, Duro-Last white roofing systems can greatly reduce energy costs.
