Search gives no answer, so I have to assume that the question is so dumb no one thinks it needs to be asked.
New construction vinyl windows with integral nailing fin, with a 5/4x4 Azek trim (Hardi plank siding). Should the aluminum drip flash go on top of the window, with the vertical leg up under the Azek trim, OR should the drip flash go over the trim?
My head says the trim should be directly over the window to ensure water is directed out, but I can't see how water sheeting down the exterior of the siding wouldn't go behind the trim. Do you flash both locations?
