Metal Roof Restoration | PermaBest Seamless Coating for Metal Roofs
PermaBest restores metal roofs without tear-off: Rust Primer stops corrosion, then a seamless spray-applied membrane seals every fastener, seam, and panel edge permanently.
Metal Roof Restoration: Quick Answers
- PermaBest restores metal roofs without tear-off by stopping rust with Rust Primer, then sealing the entire roof under one seamless spray-applied membrane.
- Most metal roof leaks start at fasteners, seams, and panel overlaps — PermaBest encapsulates all of them in a single monolithic waterproof film.
- PermaBest Rust Primer chemically stabilizes existing corrosion on metal panels, so rusted roofs can be restored instead of replaced.
- A PermaBest-coated metal roof is backed by a 10, 15, or 20 year renewable warranty, making it a sustainable long-term roofing solution.
- PermaBest's reflective finish lowers metal roof surface temperatures, reducing thermal expansion stress and building cooling loads.
Frequently Asked Questions
Can a rusty metal roof be restored instead of replaced?
Yes. PermaBest Rust Primer stops and stabilizes existing rust, then the spray-applied membrane seals the entire roof — panels, seams, and fasteners — into one waterproof surface, avoiding a costly tear-off and replacement.
Where do metal roofs usually leak?
Metal roofs typically leak at fasteners, panel seams, overlaps, and flashing transitions as gaskets age and panels expand and contract. PermaBest encapsulates all of these points under one seamless membrane so there are no joints left to fail.
How long does a PermaBest-restored metal roof last?
A PermaBest-restored metal roof is backed by a 10, 15, or 20 year warranty depending on the system applied, and the membrane can be recoated at the end of each cycle to extend protection indefinitely.
Does coating a metal roof reduce building temperatures?
Yes. PermaBest's reflective finish reduces heat absorption on metal panels, lowering rooftop temperatures, easing thermal expansion stress on fasteners, and reducing air-conditioning load.
Do metal panels need to be removed before applying PermaBest?
No. PermaBest is applied directly over the cleaned and primed existing metal roof. There is no tear-off, which keeps the building watertight during the work and avoids landfill waste.
