I have an old 20' x 20' storage building that has a very rusty roof that has a few leaks. I wanted to paint it after wire brushing the rust and priming the 24" wide 5V crimped panels.
After running the side grinder wire brush to remove the rust, I looked at the roof from below and discovered a "planetarium"with small pin head sized holes over much of the roof.
Is there any product that can fill the pin holes and prime the surface for painting?
If not, can I overlay new 24" 5V crimped panels onto the existing panels? The supporting wood is in excellent condition under the existing roof.
I am trying to avoid total roof removal and replacement. I store my golf car and tools in there and want to try to preserve it. I know the ideal procedure is total replacement but am trying to save what I have by either painting or overlaying.
If the roof is that thin and showing perforations, I think you are spending good money after bad if you are trying to fix this roof. That is just my opinion.
