I’ve got an old standing seam metal roof, circa 1932.
There are many rusty spots on this roof, and a previous owner had brushed an aluminum coating over the roof (some of which is flaking off).
So after I powerwash, wirebrush, and powerwash again, it’ll be time to prime and paint. I’m getting conflicting information about what paint to use.
Acrylic offers flexibility and oil offers water-proofing, hopefully protecting the roof from rusting too much more. Maybe an oil primer and acrylic top coat? But then the house won’t be able to “breathe.”
Any suggestions? Thanks!
