Recoating a Rusted Metal Roof

In this AskARoofer Minisode, roofing expert John Kenney of Cotney Consulting Group answers a homeowner question from Virginia about extending the life of a standing seam metal roof showing surface rust and pinholes. John breaks down why proper preparation matters and compares fibered aluminum coatings with a primer-and-acrylic system, in addition to explaining which approach delivers longer-lasting protection against rust. It’s a practical look at when a quick fix falls short and when investing in the right coating system can add years to a metal roof’s service life.
