How do you stop gutters from leaking down at the point where the roof and gutter meet?

Question

Water is leaking between the house and gutter when it rains....

Answer 1

I think you need to have a drip edge installed, which goes under the shingles, at the edge of the roof.

Also, might be that the gutters are clogged and are overflowing.

Could also be that they are not hung properly.

Answer 2

Since we cannot see the condition your gutters and roof edge are in, we will have to make some educated guesses here....

First thing to check, is to make sure the gutters are cleaned out, and free-draining. If leaves or other roof debris are clogging them up, they will hold water, instead of redirect it.

Next, are the gutters attached securely to the facia? If there are any large gaps between the guttering, and the boards they are attached too, then they probably need to be resecured.

Third - drip edge -- The metal drip edge is typically mounted under the first layer of shingles, and above the roofing felt. Drip edge should extend out from the roof, and actually overhang the gutter, just a bit.

You can put a bead of caulk along the seam of the gutter/facia. Normally, this is not necessary....but if your facia trim boards are warped, the gutters do not mount flush, etc, then you may have some small gaps there. If a gap is larger than a single bead of caulk... fix it... do not simply try to fill in the hole with caulk. This will allow your gutter, and trim boards to last longer.

Good Luck

Answer 3

You will need to caulk between the gutter and the eave. This is very important. My sister had this same problem and it caused so much rot that the water ended up coming IN through the siding.

Answer 4

add a sealant between the gutter and the house to ensure that there will be no leak and all the water goes to the gutter.
