Scene: You have a sloped roof that abuts a wall that’s covered with vinyl siding or wood panels. The step flashing has been installed from the eave to the ridge and everything is fine, right? Wrong! What happens to the rainwater that flows down the channel provided by the step flashing when it reaches the lower end of the last piece of step flashing?
The rainwater has a choice of direction at this point. It’s like coming to a fork in the road. Some of the water will correctly flow off the flashing and into the gutter. But some of the water will flow behind the vinyl or wood siding and can will most likely cause structural damage to your home!
The most common practice is to place a dollop of caulk at this point to seal the fork in the road leaking behind the siding. Is this the best way to solve the problem? Nope. After some time, usually after the warranty has expired, the caulk will fail and serious damage occurs.
By installing the lowest piece of step flashing kickout style (kickout flashing), there’s no fork in the road. The rainwater will go into the gutter and your home will stay dry. Kickout flashing is possible by simply making a 2” vertical cut in the siding materials so the flashing can come out through the cut directing (kicking out) all of the rainwater in the right direction.
On newer buildings, this cut should be done by the siding installers. For a lack of understanding, it seldom is. If you’re building a new home, insist on kickout flashing. If you have a newer home, have kickout flashing installed immediately to prevent serious damage.
The synthetic stucco trade has properly addressed this problem after learning the hard way that water can cause a lot of damage if not channeled properly. They use special kickout flashing in their siding systems. Brick walls don’t need kickout flashing since all wall flashing is external.
