0078 Roof Intersection with Siding Above - Roofing - Roof Wall Flashings -

Image Text: Siding > the siding forms the counter flashing > leave a gap to prevent wicking of moisture into the siding above > the apron of the flashing should extend 6 inches to 12 inches across the roof (6 inches is more typical) > the steeper the roof is, the shorter this part of the flashing can be > in good quality installations, the bottom edge is turned underneath > this hem makes for a stronger edge that is not sharp
