Roof flashing leak at ridge of cathedral ceiling
We have a roof leak at the flashing where a cathedral ceiling meets a vertical wall. The flashing looks like an Air Vent made Flash FilterVent which provides air flow and flashing protection. It is a clever piece. It is used to provide air flow from the soffit vents to the ridge of the ceiling. In the current literature there is a serious debate on the need for the air flow in a cathedral ceiling. Using ordinary flashing to make the repair (which would block any exhaust flow) would be much cheaper and easier. Would this be a big risk?
