Frozen Sewer Gas Pipe

Unregistered

We live in South Dakota and have a two story house. We are unable to get on top of the roof because of ice. The sewer gas pipe is appears to be frozen shut. What should we do?

Grumpy

Is it frozen at the roof line, or somewhere in the wall?

here in wisconsin I meet alot of people with this problem. It will almost always freeze up just as it passes threw the roof line. On newer two story houses I go up to the attic, cut the pvc pipe, thaw it out and reinstall w/ a coupling
