Default What to do about leaking metal roof?

My workshop has a metal roof. 2' wide V-groove pannels. The roof is about 20 years old and has begun to leak. The pitch is 8" in 10 feet.

Anybody have a clue what to do? Gotta do it on the cheap because I can't afford not to. I don't live in Pensacola but I know folks up there know more about roof repair than those who live down here.

It does not sound like it is a standing seam. You will have to re-seal the screws as they have probably broke down over time (rubber washer) and letting water pass through. Simply coat each one with roof sealer and you should be good for a few years.

Just as overkill said. You can change the screws or coat them. The cheaper way would be coating. Home Depot sells a roof coating and it would be a good idea to put a cotton mesh fabric with the coating. It's a fast and easy repair depending on the panels if they're rusting.

Default Thanks for the replies

Most of the nails seem tight. I'll slap some coating over them tomorrow if it doesn't rain---AGAIN.

I always used "Kool-Seal" elastomeric roof coating on old metal roofs and tin top mobile homes. I used a dollar store mop to apply it or you can roll it on. I comes in gallons or 5 gallon cans. A little goes along way...

Good thread here thumbs up!! I was chatting about this today and my friend told me "silver seal then a Tarp and silver seal again, tarp serves as a moisture barrier. He said it works. Thought I'd pass it along.

Default Now for "The rest of the story."

As it turned out, water was running in off the back deck and under a seldom used door. Rains every day lately have caused the boards to shrink and leaf litter plunned the cracks solid. I was kinda perplexed because I couldn't see any water stains on the ceiling.

I took my chain saw and opened each of the cracks and the problem was solved.

One thing I learned in the matter was never to use "Coolseal" on galvanized metal because the aluminum in the product causes electrolysis.

Ames makes an elastomeric coumpound that is supposed to work.

Thanks to all who responded.

By far the easiest and best way to go.
