I have a large shed (12’x16’) with a heavily rusted metal roof. I plan to try to paint it as I can’t afford to replace it. Thought I’d put 2 coats of Rustoleum Rusty Metal Primer on it and then paint it with Rustoleum Professional High Performance Protective Enamel paint. Planning to use an extension pole and a roller. The problem is that some of the metal roof panels that were nailed down many years ago have loosened along the edges because some of the nails have popped up a little and as a result the edges have sort of curled up leaving gaps where rain might get under them. It’s too steep for me to get on the roof to try to nail the edges of the panels back down plus I’m concerned about the old roof collapsing with me on it. I thought if I could get an appropriate brush or some other tool and somehow affix it to my extension pole and use roof patch, a thick type that might stay on the brush when I lift the pole to get to the repair area, maybe I could tuck the roof repair material under the edges of the curled up panels.
(1) Any suggestions on a tool or brush that I could put on an extension pole that I could buy say at Lowes to apply the patch?
(2) What type of thick patch might be good?
(3) Any suggestions on a better way to attempt this project?

Thanks!

 

would probably hire someone to get up on the roof and secure the roof back down if you do not wish to do it yourself if the wood is so rotten that it will not hold up to do that I wouldnt even bother wasting time painting it.

 

Some pis might help us advise better, both of the roof and the structure supporting the roof.
How to insert pictures.

How steep and tall is the roof? Screws hold better than nails.

 

Thanks Alan and marksr. What I think I’ll do is have a roofer check out the soundness of the shed and if it’s safe then have him screw down the panels.

 

If you can't get a roofer to come out for a small job, most handymen should be able to do it.
