A home inspection was done on my home in preparation for a sale. The inspector reported "the plumbing vent does not have adequate clearance from the fascia and should be repaired."
The vent pipe is about 4 feet from the edge of the roof. It is a metal pipe just under 3" OD. It rises about 10 inches from the roof. The peak of the roof is about 12 feet away and about 2-3 feet above the top of the pipe.
My home was built in 1965. Is there a good reason why the vent pipe should be extended? If so, how high?
Huh? 4' from the fascia and 10" above the roof surface sounds reasonable to me, unless your local code is really strange.
Did you contact the inspector as to what he thought should be repaired? If nothing else "does not have adequate clearance to fascia" doesn't sound like something that could be "repaired" by extending the vent pipe.
I did not contact the inspector. I think height was his concern. He mentioned that being low might be responsible for a slow running drain. I was not the cause -- I fixed the drain. I think by "being too close to the fascia" he was really saying it was too low and should be higher up the roof.
I will answer this item by explaining that I do not think it is a problem. If the buyers wants to pursue it, they can ask the inspector to explain its importance.
The International Residential Code & Plumbing Code leave the distance to roof edge and distance above roof to local authorities. I'd check with local plumber or code official.
Architect across the street was given what he describes as a multipage list of inspection items by a prospective buyer. He told them it was being sold "as is". The buyer caved in.
It sort of sounds to me like he was thinking of requirements for a chimney instead of a plumbing vent.
A plumbing vent only needs to be open to the outside atmosphere a minimum height (something like a couple of feet) above the highest flood line for fixtures it serves.
A chimney needs to be high enough so that passing air causes a low pressure up draft in order to draw flue gasses up and out. Typically, if its top is not sufficiently high enough above the roof surface, the peak of the roof will shelter it from winds in some directions and prevent it from functioning properly.
I recall that in some heavy snow areas it must be higher than that.
