I’m not sure what material my roof flashing is except that it is a metal. It started out a whitish or silver color and over the last 10 years has slowly rusted until I’ve finally noticed it. Shame on me.
I don’t believe it is rusted through but it is rusted bad. I got up there and began sanding with wire brush and various grades of sand paper and under the rust is black. I don’t know if that’s black rust or if the rust/I made it through some coating. I’m trying to figure out if there is an alternative to replacing it.
I’ve sprayed a small portion with rustoleum. The kind that coverts rust. Is this a legitimate way to preserve what’s left of my flashing? What should I be mindful of if I use this technique. I sanded it down the best I could. Even got a dremel tool. Rinsed it with soap and water. Hoping I washed it well enough, And depended on the rustoleum to do the rest.
Is this viable? Is there a way to tell if I prepped well enough and the paint is working? Or is there no way to tell until the flashing rust through and destroys?
The black at the top is the section I did after sanding.
