While on the roof and I have something I have never seen. The 3 inch PVC pipe that extends out roof, is inside an all metal roof flange. I understand the purpose but don't think it was installed properly. It appears that the waterproofing between the PVC pipe and the Metal Flange is accomplished by bending the top edge of the metal pipe down inside the PVC pipe.
It appears to have been POUNDED in place, with the PVC pipe being app 2" below top surface of metal flange!
The metal appears to be soft and I assume it is a Lead alloy??????
Other then the small leak, I believe the 3" PVC is essentually a 2" because of the sloppy installation of the wrinkeled up metal.
Is this something I should be concerned about--I am having NO Vent problems?
