How to Repair Loose Flashing Between Sections of Buildings

  • Transcript

    LESLIE: Alright. Tom in Missouri is calling in with a pretty crazy question. His garage is pulling away from the house. Tell us what’s going on.

    TOM IN MISSOURI: My garage is pulling away from the side of my house. And we determined it was a gutter-overflow problem and we got that rectified. And now I’m wondering how to get my garage back up to where that it’s not pulling away from the house. It’s pulled away an inch or so.

    TOM: OK. Once a building moves, because there is water that got under the foundation or whatever caused it to rotate, you can’t shove it back to kind of close that gap. So, you need to get used to it in its present position.

    But tell me this: is the gap that’s opened up, is that a problem from a weather perspective? Is water getting into the building?


    TOM: Does the roof of the garage attach to the side of the building above it or next to it? Is that where the leakage issue is?


    TOM: Alright. So what you’re going to need to do is you’re going to need to reflash that: essentially take apart the roofing in that area and replace it, reroof that 1- to 2-foot strip between the garage roof and the adjoining building. Because that’s pulled apart, I can only imagine that all of the flashing is extended and there’s lots of places for water to get in there. If you don’t do that, during driving rain the water will get down between the garage roof and the second-floor side wall of your house. And that’s going to cause leaks and rot and all kinds of problems.

    So you’re going to have to tear out the roof where it joins the building and replace it. But now that you’ve fixed the gutter problem, you’ve got the foundation stable again, that should really take care of it for the long run.

    Tom, good project for you there. Thanks so much for calling us at 888-MONEY-PIT.
