I previously posted a question about a plumbing vent problem pointed
out by a home inspector. I found later that the vent I thought he was
talking about was not the one I looked at.
The plumbing vent in question serves a bathroom.The vent pipe rises
about 5 inches from the roof and about 1 inch above the flashing
assembly that fits under the shingles. The problem is that there is
another gable just above the pipe. The fascia of the top gable has
been notched a bit to accommodate the vent pipe. A small portion of
the vent pipe is blocked by the fascia.
The inside diameter of the steel vent pipe is 1 7/8 inches. If you
look straight down at the vent pipe, the diameter is effectively 1 1/4
inches, because the fascia board blocks 5/8 inches of the diameter of
the pipe opening.
It looks like a problem to change. I thought about putting in some
extra pipe with 2 right angle bends to get it away from the fascia,
but this would require ripping off the flashing assembly, cutting the
pipe near the roof and trying to get proper flashing around a pipe
that bends just an inch or two above the roof. The whole thing is just
a foot away from the roof edge and a problem to work on.
The house is 45 years old, and the vent has not caused any problems
that I am aware of. Any comments on what should be done? I can send a
couple of photos if you want to see it more clearly than I described
