How do you fix a leaking metal hangar roof?
Looking for some recommendations on how to repair a few leaks in the roof of a metal hangar. What do you guys recommend?

Call a professional. :)
In my case the foam seals at the eaves had slightly rotted and some of the 16 year screw sealing rings had rotted in the AZ sun. This let the screws loosen a bit. In another spot extra screws on the roof panel lower edges (above that called for in the plans) helped seal from westerly driving rain. Interestingly the rubber seals on the screw heads apparently have changed and improved since my hangar was built. They promise it's now fixed. :) |

R&R Screws/Seal
Actually having mine done today...Screws replaced with larger sealed caps and topcoat with a good sealant. The metal roof on wood beams will always be an issue due to expansion,moisture,ect. Hopefully, I can get another 5 years or so before it needs attention.

+1 for professional
Just had my roof done, the company cleaned all rust etc., primed, taped all screws and edges and then applied some form of polymer based coating. Supposed to be good for 20 years. Have had no leaks since.
Prior to that I had the foam insulation sprayed on the inside which stopped a lot of the leaks but still had some drips here and there. Figs |
seems like a foam on inside would be worse than a leak. traps water and doesn't allow it to evaporate. plain old roof patch tar on the offending / nails on the roof took care of all my leaks.
first draw a''map'' of the roof from inside the hangar showing the leaks. then when you are op top you get the right fasteners. pretty painless, easier than I had expected. |
Roof
The county that I rent from just replaced roof on hangar they used tin of a building they took down the holes did not line up with the beams in my hangar so there was about a thousand holes you could see daylight the hangar is 60x60 I ask the head guy why it was not going to leak worse than before he said when he got through it wont leak I told him he was crazy.Well we have had some pretty good rain in the last 3 months and no leaks here is how he said he was going to fix holes SILICON and COOLSEAL guess it worked no leaks.

Be sure that the roof is actually leaking, and it's not just condensation building up on the underside and dripping down.

Thanks for the replys guys, for those who recommended a professional; how did you find them? I would definitely want a quote from a pro before I attempt it. Do i just start calling roofers?
