Kickout Flashing

Water; the element that falls on the house, runs through the pipes, and if not contained, will cause extensive damage to the home and its contents.

Flashing; a thin piece of watertight material that is installed to prevent water from passing into a structure through an opening.


Does your roof have kickout flashing installed?

When water falls on a house, the slope and design of the roof direct rainwater into a gutter. The gutter is connected to a downspout that sends the water away from the home so it can disperse into the ground. A key component to directing the water into the gutter, instead of running between the gutter and the siding, is kickout flashing.

This cheap and easy to assemble piece of metal is often missing, resulting in water bypassing the gutter and draining to undesirable areas, such as behind the siding.

When kickout flashing is insufficient or is missing completely, it is not unheard of to find significant moisture damage to areas under the gutter. This usually starts just below where the end of the gutter meets the wall. Homeowners typically never notice the damage occurring until water staining is observed or insect related activity becomes apparent.

Here are two different homes that we observed having metal flashing installed to act as kickout flashing but neither were of an effective size. In each case, water was draining between the gutter and the siding, collecting on and deteriorating the trim around the windows below.

Pictured below is a metal roof that intersects with a wall surrounding a chimney flue. We observed the lack of kickout flashing and probed the siding for signs of moisture damage. The probe easily pierced through the sheathing behind the siding, which indicates that heavy deterioration was occuring. This one required removal and replacement of the siding and other rot damaged components.

The last photo is of kickout flashing installed and functioning as intended. This is what you want to see!
