In case anyone ever wondered about the importance of a kick out flashing???
Here is a great example. It took years, but the water ran down the wall and behind the shutter until finally it rotted through the clapboard siding.
This house was built around 1900 and the only area of siding damage was below where a kick out flashing should’ve been. Yes some of the window sills were rotted, but overall for a house this age the exterior was in relatively good shape.
