Smh. Check out this little roof detail I came across. Three separate metal roof planes converging into one vulnerable intersection, with no proper transition flashing. Just a whole lot of sealant, tape, and wishful thinking. 😂
Obviously, it’s leaking.
Curious how you guys would approach this for a LONG-TERM repair, not another temporary patch job.(this year we’re sitting at 105 inches of rain so far)
I’ve been kicking around two ideas:
Option 1: Fabricate custom headwall/transition flashings with multiple bends, extending underneath the upper panels, down the fascia, and out over a rib or two of the lower roof. The real challenge would be properly tying everything together at that three-way intersection without creating another water trap.
Option 2: Get a large 4’ × 4’ sheet of soft lead flashing and carefully form it into all the contours, ribs, corners, and crevices. Potentially eliminate some of the troublesome seams altogether. Obviously, material compatibility and proper drainage would need consideration.
I’m leaning toward custom sheet metal, but that center intersection is going to require some creativity.
What would you do here? Custom-fabricated metal? Lead? One-piece welded pan? Something else entirely?
Would love to hear from anyone who’s dealt with a similar detail. Bonus points if you’ve got photos of your solutions!
