Jim Katen Posted September 19, 2020 Report Share Posted September 19, 2020 I've never seen this before. It's a standing seam steel roof on a log house built in 1978. I presume that the roof is original. It's located in the coast range forest, about 2 miles from the Oregon coast. (As a side note, does anyone know how to distinguish between galvanized steel panels and galvalume steel panels when they're painted like this?) This roof has many spots where the paint is gone, the zinc (or aluminum) has worn away, and the steel is rusting rather badly. Aside from those spots, the coating remains in good condition. Question: Can these rusting spots be prepped, primed, & painted to produce a durable result? Or would such an attempt be akin to patching a bald tire?

Chad Fabry Posted September 19, 2020 Report Share Posted September 19, 2020 Automotive paints will last 20+ years after sanding, prepping with a rust converter and an etching primer. I bet that most of the rust is the result of rough handling during installation. Link to comment Share on other sites More sharing options...
Bill Kibbel Posted September 19, 2020 Report Share Posted September 19, 2020 Perpetual whack-a-mole as new spots will appear. Why the screws? The gaskets are likely going to fail soon. The major advantage of selecting standing seam is the elimination of exposed fasteners. I would advise applying a preservation coating system. http://preservationproducts.com/roofing-systems Link to comment Share on other sites More sharing options...
