Here is the culprit.
A unsealed attic access hatch in the bathroom of the upper level that will be behind the mirror in this room.
This opening was flooding that roof section with heat, and causing the snow to melt. It would then run downthe roof, till it hit the overhangs, where it froze again, and started building ice dams.
Simple fix, is to add the rigid foam insulation to the opening, seal it off, and cover with drywall, which completes the air barrier again.
This is exactly why open soffits from the rooms below into the attic space are so bad. They leak the equivalent of air that this opening did, but you wouldnt know it was happening till something like the ice dams occur.
By the way, its negative 14 degrees this morning. Brrrr.
