Any rainwater or in sparodic areas then simply misses the gutter.
Water dripping between gutter and fascia.
Unfortunately it doesn t always work that way.
A gutter apron is a bent piece of flashing that tucks up under the shingles and over the gutter.
Usually this is due to gutter fasteners rusting.
If you re not closely attuned to the behavior of your home s water drainage system you may not notice this occurrence.
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.
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.
But what happens when your roof s gutters become worn out or cracked or clogged.
This problem is common with homes that have roofs that do not have much pitch to them.
When water drips between the fascia and the gutters the problem could be a compromised drip edge but it s also possible the gutters are overflowing.
If water is dripping behind your gutter it s probably because it was installed without any flashing over the back of the gutter.
When properly installed gutters direct roof runoff into a downspout system and safely away from the house.
This then pushes the guttering out from the roof line by 9 17mm.
The gutters then direct the water to a downspout allowing the water to run down until it reaches the ground.
Water leaking between gutter and fascia when there is rain the water is expected to roll down the roof and into the gutters.
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.
For gutters to work properly they must be properly sloped toward the downspouts and the roof must have a drip edge that clears the sides of the gutters closest to the house.
The gutter apron will prevent the dripping.
For example most ranch style homes have a 3 12 or 4 12 pitch roof.
Home centers sell a gutter apron in 10 ft.
