How to Find and Fix a Leak in a Metal Roof
LESLIE: Dale in Wisconsin is on the line with a leaky roof. Tell us what’s going on.
DALE: Well, we’ve got a metal roof. It’s a Pro-Rib system? Think of it as a pole barn but the basic structure is made out of metal trusses and then roof purlins and side girts.
DALE: And I’m assuming that they’re coming in from around – the leaks are coming right – because it’s not a lot of water. You know, if I put a measuring cup underneath one of the drips, it probably wouldn’t fill up unless it was a really, really torrential rain. And then it also depends on which direction the wind is blowing.
TOM: OK. So what’s your question, Dale?
DALE: I’m looking for a hint on how to repair this, because I was hoping this was going to be my last house.
TOM: Alright. Well, first of all, you need to figure out where it’s coming from exactly. Is it possible to get on the roof?
DALE: Yeah. But I’m not as young as I used to be and I don’t bounce quite as well.
TOM: Yeah, I hear you.
Because one way to kind of track it down is to wet down different sections of the roof with a garden hose to try to figure out where the breakdown is. And then from there, if you can track it down to just one or two panels, I mean I would silicone-caulk it just to see if it stops it or slows it down.
And if that’s the case and it works, great. If it works for a while but then doesn’t work any further, then probably you’re going to have to have a roofing contractor take apart those sections where the leaks are and then seal them that way.
DALE: OK. Sounds like a good plan. Thank you very much.
