How to Locate a Roof Leak
LESLIE: Lois in Wisconsin, you’ve got The Money Pit. How can we help you today?
LOIS: Yes. My husband’s been up on the roof twice now and he can’t find where the leak is leaking in our kitchen. And he can’t find out where it’s coming from.
TOM: Is there a vent pipe right above that area, like where the kitchen sink is?
LOIS: I’m not sure but …
TOM: Typically, there is because all plumbing fixtures have a vent pipe. And where that pipe goes through the roof, that’s where I’d start.
Now, roofs typically leak wherever there’s an intersection or a pipe comes through like that. And so I would take a look right above that. Now, keep in mind that roofs can leak farther up above where they’re actually showing up. And the water can sort of go down the roof rafter, sort of hang against gravity, then drip when it gets down towards the end. So, anywhere above that is where it’s going to – you’re going to find that leak.
Now, if you look and you can’t figure it out, why not get up there with a hose and wash down the roof; see if you can make it leak.
TOM: And between those two things, you ought to be able to find it.
LOIS: Alright. OK.
TOM: Alright? Be careful on that roof.
LOIS: Yeah, that’s for him.
TOM: Alright. Thanks so much for calling us at 888-MONEY-PIT.
