Here are a few guidelines you need to follow to get it right.
Gutter leaking behind gutter.
If clips or brackets hold your gutters check for broken clips and loose or missing screws.
If you can t see anything with your naked eye you can also try pouring water into the gutter and then making a note of every spot where it leaks out.
Place downspouts in areas with the least amount of obstructions electrical wires hose bibs sidewalks etc.
1 your roof sheets have a hole in them or your screws or nails or equivalent are not watertight anymore or 2 the more common reason is where roof sheets are cut too short or they don t overhang far enough into the gutter.
Should you notice the gutter leaking in one or a few small ish spots you ll want to carefully inspect the area to see if you can spot either of these problems.
Water leaking in behind the facia of your roof could be caused by a couple of things.
On some homes water tends to drip behind the gutters down the fascia and soffit and then either down the side of the house or straight to the ground.
Put downspouts in a hidden location to ensure that they don t detract from your home s overall look you can camouflage.
When the roof shingles do not extend past the metal drip edge the water will suck back on the metal drip edge this is called capillary action and run behind your gutters.
If you re not closely attuned to the behavior of your home s water drainage system you may not notice this occurrence.
