How the retrofit installation works

  1. The Duro-Shield roofing system is applied over your existing metal deck with no tear-off required.

  2. The flutes are filled with insulation cut precisely to fit.

  3. A second layer of insulation is added to create a flat surface and increase the R value.

  4. A prefabricated membrane is mechanically attached to the deck.

  5. Prefabricated flashings for stacks and other penetrations are heat welded to create a single covering that forms a leak-proof seal.






Has Time Caught up to Your Metal Roof?

Duro-Last Metal Retrofit is the solution! Avoid replacing your metal roofing by covering the roof with PVC single-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.

The Prefabrication Advantage

Through our custom prefabricated retrofit roofing systems – which can include both membrane and accessories – up to 85% of the seams can be completed in our factory-controlled environment. This eliminates most of the on-site fabrication that can lead to roof leaks. Increase your production and profit!


By reflecting up to 88% of the sun’s energy, Duro-Last white roofing systems can greatly reduce energy costs. Learn more about how Duro-Last contributes to sustainability.
