Great pictures, Moose! Based on the amount of snow that's on the roof, I'd be concerned about snow/ice dams causing under-shingle backup. Do you get up there and clear it at all? Looks like a pretty steep pitch. Hopefully that slope would eventually take care of unacceptable build-up.
Thanks again, those photos brought back memories of northern New England blizzards. Nothing like being able to leave the house by a second-story window!
