Before & After – Metal Roof Restoration This commercial metal roof had heavy oxidation, rust bleed, and fading from years of exposure. We restored it using PB 90 silicone roof coating after proper surface prep and corrosion treatment. The result is a clean, bright, fully sealed roof with improved waterproofing, UV protection, and reflectivity—without the cost of replacement. If your metal roof is showing rust or wear, restoration is a smart, cost-effective solution.
