Metal Retrofit Roofing
Cost-saving single-ply overlays installed directly over old, leaky metal roofs without disrupting business operations inside.
System Specification Overview
If your existing metal roof is rusting or leaking at the joints, complete replacement is not your only option. Our Metal Retrofit Roofing installs a high-performance single-ply TPO or PVC membrane directly over your existing metal roof. We insert custom-cut flute-fill insulation between the metal ribs, forming a flat substrate for the final waterproofing sheet. This saves massive removal costs and completely avoids building downtime.

System FAQ & Specifications
DO WE HAVE TO CLOSE OUR WAREHOUSE DURING A METAL RETROFIT?
Absolutely not. Because the existing roof stays in place, there is zero risk of debris or weather falling inside, allowing your business to remain fully open.
HOW MUCH ENERGY DOES THE FLUTE-FILL INSULATION SAVE?
Flute-fill insulation typically adds R-10 to R-20 insulation value, resulting in huge drops in warehouse utility bills.
