Hi Max and Bill,
Thanks for your input. The actual plumbing vent
will be rerouted to go out of the north pitch of
the roof. There will only be a an open pipe left
in the attic. The main issue is finding ways of
keeping water out of the vent pipe (now
abandoned) and getting it short enough to fit
under the array. I think a cap on the pipe would
make it too high, so I'm looking for other ways to seal it.

So this is a plumbing vent instead of a furnace
or hot water exhaust vent? Ive used Fernco
rubber caps on unused vents, with the screw down
pipe clamps around the bottom. Also these are
just to allow air into the vent so draining
water doesnt create a vacuum so I suspect there
is little to be concerned about with cutting
them off just above the roof flashing and
allowing enough room over the top to allow air
to flow into it. On a three inch vent that is
only ¾ to equal the surface area of the pipe.
The top of the flashing is protected by the
module over its top. Over time would there be
sewer gases which might cause trouble on the
back sheet of the module? I dont know.

Hello Wrenches,
We are moving a roof vent. My plumber suggested
that we cut the old one and cap it instead of
having to repair the roof. I'm not sure a capped
vent would be short enough to fit under the array.
What if we were to cut the vent off at the
flashing level and plug the pipe. A rubber plug
could be put in and topped with hydraulic
water-stop cement. Neoprene roof sealant could be spread on top of that.
Has anyone tried anything like that? Are there
any other good options? Can you see any issues with this method?
Thanks,
Drake
