Durolast Metal Retrofit Systems

PVC Single-Ply Membrane Over Metal Roof System

Has time caught up to your roof? Duro-Last Metal Retrofit installed by Phoenix Construction Group 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.

We believe we can be an asset to your organization, and fully understand having to work together to achieve common goals.

The Prefabricated Advantage

This eliminates most of the on-site fabrication that can lead to roof leaks and adds the advantages of a faster, quieter and easier installation, with less maintenance and reliable roof performance for years to come.

Experience the “Prefab 4” with Duro-Last:

  • Less labor for Time off the Roof™.
  • Factory welded seams mean better first time quality and fewer callbacks.
  • Prefabricated accessories provide easier installation at transitions, offer superior waterproofing and deliver improved aesthetics.
