My bad, probably a little snippy for my first post here but I've been hanging around and feel I know some of you guys. I do know Chad and his, shall we say, fondness for proper terminology. "Step flashing" in the local jargon would be woven into courses of shingles of some kind or other that is then covered on the vertical side by either the siding or a counter flashing or both. In any event, the proper technique for John's post would be for a continuous flashing from the wall onto the waterproof membrane under the metal, a bead of approved sealant, the metal roof panel, a bead of approved sealant, another continuous flashing, and a counter flashing that is cut into the brick. What he has is a sloppy metal roof-over that is unfortunately all too common. Tom
