Water Splashing Behind Guttering

Have rain water dripping out from between your facia and gutters.

Water splashing behind guttering.

Capillary action is a water activity in which water adheres to a surface and follow the surface around. Home centers sell a gutter apron in 10 ft. 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. This can be frustrating and also creates a dangerous situation on porch steps during freez.

There are a few elements that come into play that cause water to run behind the gutter. The first cause is when the roofing material is installed many roofers will not extend the roofing material past the roof edging or drip edge. Rainwater leaking from a gutter ends up behind siding and causes a wall to rot. At some point in the past an owner had vinyl siding installed over old siding.

If water is dripping behind your gutter it s probably because it was installed without any flashing over the back of the gutter. Ever wonder why that is. The extra thickness of the vinyl. In roof valleys rain water will travel faster especially during a heavy storm or if the gutters are already full and the water will skip over the gutter and right onto whatever or whomever is unlucky enough to be beneath it.

A gutter apron is a bent piece of flashing that tucks up under the shingles and over the gutter. Thankfully there s a fix for this and it s called a gutter splash guard. You can find these precut gutter splash guards about 3 in brown and white aluminum at a home center but you could easily make your own out of aluminum or sheet metal and spray paint them to match your 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.

Are you getting water behind your gutter. Holes through the splash guard and the gutter.
