I am building a new detached garage, and the forecast this weekend is just warm enough that I plan to get my trusses and roof sheathing up.
My sheathing is 5/8" plywood (not OSB). It's a single car garage, 12' by 20'.
However, the weather won't be above 40F / 4C until the spring, so I won't be able to shingle for some time.
How should I protect the bare roof sheathing to best survive the winter?
I am in Wisconsin, USA, so expecting lots of wind, snow, and frigid cold.
These are the options I am thinking of - are there better alternatives?
- Install tar paper underlayment and ice dam only
- Install underlayment / ice dam and spread a tarp or plastic over the whole thing
- Tarp over the bare sheathing
