Leaking roof on pole barn

[Beetle]

My metal roof on my pole barn is leaking in about 3-4 spots during a hard rain. This pole barn is uninsulated and is 30 years old. When built nails with neoprene washers were used in the flat of the metal. I have obtained some screws with washers and plan on pulling the nails and replacing with screws. My metal is in good shape but I still would like to put some sealer on the screw or a shot down into the old nail hole just to be sure. Any advice on the type or brand sealer that would work best. I don’t want to put something in the nail holes that’s going to cause problems down the road. Thanks

Sealant will fail. The proper way to do it is pull the nails and replace with slightly larger metal roofing screws so they can bite into good solid wood.

Make sure it's dry as possible and shoot a dab of 100% silicone caulk in there before screw and washer. Sealant IN a joint can't really fail, it's got nowhere to go and it isn't exposed to the elements.

I might not have been clear in my description. I plan to pull the nails then add a little shot of sealant (if recommended) to each hole prior to putting in a new screw.

No I got you. It’s just not necessary and won’t do anything for you.

Nowhere can I find a manufacturer who suggests using any sealant or caulking with their fasteners.

Good luck!

Agree with you as best course of action to fully repair. Sealant will buy some time though. OSI is pretty good if OP wants to (or needs to) put off doing a full repair for a few years. I just used PL Pro Polyurethane on a roof vent stack repair that I'm hoping will outlive the remaining useful life of the three tab shingles currently on roof.

Yes that’s where I was trying to get you.

One word for you......... Henry: https://us.henry.com/roofing/roofing-sealants/henry-884-tropi-cool-silicone-roof-sealant

By that reasoning sealant should be used in new installations. Pull the nails and simply install larger diameter screws. Done.

A company called Kwik-Kap Co. at 281-399-9334, New Caney Tx. sells an aluminum cap that you apply over the existing screw or nail to seal the leak. You use a provided tool to set the cap over the screw. These caps work great. Look up this item at the Farm show website and you will see what I am describing. I don’t think they have a web page. You get 1000 caps for like $95.00 plus shipping.

Pull em out with vicegrips, shoot NP1, silicone, osi quad or whatever is your favorite, impact drive a slightly thicker roofing screw ( I buy through bestmaterials.com)

Life is good. Ring shank nails **** big time.

The reason sealant is not used on new installs is probably two fold, potential warranty issues and labor+ materials. Wont hurt anything... especially since those ring shank nails tend to tear the sheet metal into oblong shapes where they fail.

I have a similar issue. A couple of years ago, I replaced every single screw in half of my roof. It dramatically slowed it down, but not 100%. That's why I haven't finished the inside of my barn. As it is, it has a chance to dry. I still need to do the other side, but like I said, it didn't completely stop it.

so I have nails (w/ rubber washer) in the roof of my old pole barn and this is my current issue (barn was built that way before I owned it). Having read 100s of webpages and articles on fixing the slow drip some of the nails have, yours is the first and only suggestion for this product I have read- anywhere.

So you have used these? who did you get them from? Have been digging on Google but having trouble (so far) locating the tool and finding pics or video of how this works? I found the company # and called (they were not open), do they make this product anymore? Am seeing this from 1999.

Not to mention the incredible time waste of gunning sealant into every hole...the guy charging for that benefit would never be able to keep up.
