Ice dam caused by vent stack
This is only my 4th winter in my current house so I haven't experienced all types of "weathers" yet so I don't know if something is wrong.
I know that my attic has a vapor barrier sheet and is insulated with R52 fiberglass (Did it myself before the first winter). So unless something got broken up there (no mouse problem), the insulation should be fine.
The main part of the ice dam is really just in front of the vent stack over my main bathroom. Considering the vent stack is copper, I assume that heat from running water transfers much more easily up into the attic and right over the roof area around the stack.
Is this something normal when we have such mild temperatures that dip below 0c at night?
It is a bit embarassing, a lot of neighbors have ice dams, but mine has icicles reaching 4 feet of lenght
