Kickout Flashing

Component -Kickout flashing (diverter) is flashing installed at the lower end of a roof-to-wall transition to direct water away from the wall.

Why Is Kickout Flashing Used in Roofing?

Kickout flashing is used where a sloped roof meets a wall and the wall continues past the roof edge, such as beside a chimney or sidewall.

Step flashing moves water down the roof-to-wall transition. Kickout flashing turns that water outward at the bottom of the transition so it reaches the gutter or eave instead of continuing down the wall.

Ineffective or missing kickout flashing can disrupt the water’s intended drainage path. Flashing that is too small, missing or bent the wrong direction can cause water to run behind siding, soak fascia and cause interior leaks.
