We had what is hopefully the last snow of the season a week ago, but today was in the 60s.
The metal roofing is finally going on.
A learning experience, but no serious misteaks so far.
The skylights are (temporarily) in -- they will come out breifly when the skylight flashing goes in. I've used some Grace's all purpose flashing around the skylights, which isn't leaking, even w/o the roofing.
