Thanks again, I like this posting thing...I'm glad Brian forced me out of the inspection closet.
As you are in an area with a good amount of snow and ice, I would recommend that they place an elbow on the end of the pipe so it is turned down. This will help to keep out snow, falling golf balls, etc.
Another thought is that PVC does not have any UV protection and after a few years that pipe will become brittle. Yes, it happens to even smaller vent stacks, its just that they are not as exposed. Spraying them with a protective paint will help to protect it and will also make it blend in better with the surrounding roof, that is if they use a paint to match the shingles!
