We will inspect your facility to determine the nature of the problems and whether repairs or re-roofing may be required. Metal retrofit roofing involves installing infill, adding overlay insulation, and a single-ply roofing membrane. This adds insulation value without the high cost of removing and replacing the existing metal.

Overall, this proven system provides a cost-effective, long-term way to protect buildings against rain, temperature changes, interior drips, ice build-up, rust and corrosion, while significantly improving energy efficiency.
