Finished for the year. I just wanted it winterized. Well more like springrised... the snow is the the issue, it's the rain and wet weather. Still need to do siding and shingles. Hopefully the tar paper will hold alright during snow melt.
If it's #15 asphalt felt (not "tar" paper ugh) then you might want to put two layers on if you are going to leave it all winter. I'm not an expert in cold weather roofing but felt is dirt cheap, you might even have enough left over, installs quick and won't impact your shingle install.
