TOPIC: I Have An Existing Metal Roof and Have A Question

Ridge Cap - Superspan Roof Rib seam syphoning?

Return to I Have An Existing Metal Roof and Have A Question

Return to Forum

I have inside drips under the ridge cap. Metal Ridge cap is simple 'flat' 9'' overlap (end over end) seams, for each 10 ft. length across a 50' peak. Each length over lap seam had 2 vertical silicone caulk beads 3'' apart. The Metal Roofing is silver Super span. Pitch is 27 degrees up from flat. Ridge cap covers a foot of super span on each side of peak. Cap total width including both sides is 30''. There is a tin "valley" under ridge cap as well, just as a secondary. How can it be leak-dripping under the center of that Large Ridge Cap and 'secondary valley' under cap? ( Drones-Aliens pumping water in through the peak vents on each end?? LOL. ) I suspect some sort of syphoning action? Most people want to tape, glue, paste, etc . Would the correct thing to do is "gap" the top end of overlap seams, to break the syphon ability? Can i slip a dime or nickle in between superspan seams at top end, way up under ridge cap to halt syphoning? Help.
