Plumbing vents exiting ridge cap
Can’t seem to find anything in the code, easily missed though. I have a customer who wants a metal roof installed however they have had bad experiences with pipe flashings through the roof and don’t like the look of them. While I don’t care for the pipe boots, (for metal roofing), appearance they seem to work well.
Anyway, to the question… Is there anything code or common sense wise that says vents couldn’t go through the ridge cap? I know it wouldn’t look as good but, would limit water flowing over them.
