I few years ago I posted on this topic that when it gets below 10F my bathroom vent pipe (2") freezes over and I get gurgling noises in my tub and i'm getting around to deal with it. Now someone suggested i expand my vent pipe in the attic and run it out the roof in it's original location. Well I do not want to cut a larger hole in my roof to accomplish this. Roof is getting old and may need replacing soon. Can I insulate this vent pipe above the roof with some type of wrap to prevent this, would this eve work? Or can I cut most of it off above the roof install a coupling and expand from there? Not sure if this would help. Not sure if the coupling will hold when we get the 60mph winds.
