Almost every siding failure we open up in Greater Seattle began at a junction: a missing head flashing, no kick-out where a roof meets a wall, cladding running into the grade. Water gets behind the boards, finds nowhere to leave, and goes to work on the sheathing and framing where nobody can see it. By the time it reaches you as a soft wall or a window that will not close, you are no longer repairing siding. We treat the cladding, the barrier, the flashing and the structure as one assembly, because that is what it is.
