DEnd, thanks for the links.

I read them a few months ago, good to refresh though.

Some reasons why I don't think I will have ice dams:

Bottom of roof sheathing, all rafters, & wall top plates will be completely encapsulated with R-50 closed cell SPF. No warm air from inside the house will get to the roof, no penetrations through roof, Radon & DWV vent pipes exit high up through the rear gable end wall. (Yes this meet code & is described therein)

This type of steel roof, sits up on horizontal 2x2 Batton's, with some air flow under them.

I never had ice dams on my last very similar house & climate zone.
