There are a few things that you can do to stop water from leaking behind your gutters. One is to install gutter screens, which will help prevent debris from clogging the gutters and allow water to flow through them easily. You can also install gutter extensions, which will help direct the water away from the house. And finally, you can make sure that the gutters are properly aligned and secured to the roof.

You can stop water from leaking behind your gutters by ensuring that your gutters are properly installed and maintained. Gutters should be tilted slightly downward so that the water drainage is directed away from the house. The gutter seams should be sealed with waterproof caulk, and the gutter extensions (downspouts) should be directed towards a storm drain or landscaping feature that will safely channel the water away from the house.
