Metal Roof Restoration & Coating for Commercial Buildings
Rust, loose fasteners, and leaking seams don't always mean a new metal roof. We restore commercial metal roofs with American WeatherStar coating systems, keeping the panels you already have and sealing them against water.

Why commercial metal roofs leak
Metal roofs on shops, warehouses, plants, and other commercial buildings are tough, but they wear in predictable ways. After years of snow, freeze-thaw cycles, hail, and sun, we usually find the same problems:
- Fasteners. Screws back out as the panels expand and contract, and their rubber washers dry out and crack. Each one becomes a small hole in the roof.
- Seams and laps. Panel laps open up, and old sealant fails.
- Rust. Once the factory finish wears through, rust spreads, especially around fasteners, at panel ends, and in areas where water sits.
- Skylights, curbs, and penetrations. Weathered skylight panels and poorly flashed curbs and pipes let water in.
- Gutters and drainage. Damaged gutters, scuppers, and downspouts back water up onto the roof and into the building.
A metal roof restoration fixes those problems and then seals the whole roof with a seamless coating, usually for far less disruption than replacing the panels.
How we restore a metal roof
Inspect
We walk the roof and mark rust, loose fasteners, open seams, damaged panels, skylights, and drainage problems. Your first inspection is free.
Clean, treat & repair
The roof is cleaned, rust is treated and primed, fasteners are tightened, replaced, or sealed, and seams and penetrations are reinforced.
Coat
An American WeatherStar coating system is applied over the prepared panels, forming a seamless, sealed surface over seams and fasteners.
Example: Hewescraft, Colville, Washington
For Hewescraft, a boat manufacturer in Colville, Washington, we took on a large metal-roofed plant with drainage and leak problems. The work included a gutter rebuild, drainage and leak repairs, and coating restoration on the metal roof. It's a good example of how restoration works on a big metal building: fix the water problems first, then seal the roof.
Metal roof restoration vs. new metal panels
Restoration makes sense when the panels and structure are still sound and the problems are mostly at fasteners, seams, rust spots, and details. New panels may make more sense when rust has eaten through large areas, the panels are badly deformed, or the structure underneath needs work. We'll tell you which one your roof needs, and why. See our roof coating vs. replacement guide for more on how to decide.
Acrylic and silicone coatings for metal roofs
Acrylic coatings are a common choice for metal roofs that shed water quickly. Silicone may be a better fit for low spots and low-slope sections. Many metal roofs also have flat or low-slope sections, valleys, or gutters that need different details. We match the roof coating system to the roof.
We restore metal roofs in Missoula, Kalispell and the Flathead Valley, across Montana, and in North Idaho and eastern Washington.
Metal roof restoration FAQ
Can a rusty metal roof be restored?
Usually, yes, if the panels are still structurally sound. Surface rust is cleaned and treated, and badly rusted or damaged panels are repaired or replaced before the coating goes on. Panels that are rusted through across large areas may need replacement instead.
Do you replace or seal the fasteners?
Loose, missing, and rusted fasteners are a common leak source on metal roofs. We tighten, replace, or seal them as part of the prep work, then coat over them.
Does a coating help with metal roof leaks at seams?
Yes. Seams and laps are reinforced during prep, and the coating forms a continuous membrane over them, which seals the most common leak paths on a metal roof.
Will my building stay open during a metal roof restoration?
In most cases, yes. The work happens on top of the roof, so most shops, warehouses, and plants keep operating.
What does metal roof restoration cost compared with a new metal roof?
It depends on the roof's size, condition, and the repairs needed, so we price each roof after the inspection. Because the existing panels stay in place, there's no tear-off or disposal of the old roof.
Is your metal roof worth restoring?
Start with a free roof inspection. We'll tell you whether your metal roof can be restored with a coating, needs repairs, or needs new panels.
