General Contractor has been hired to build a wrap around porch onto our house. He has most of the construction completed (decking, columns, soffits, etc) but still has not shingled the roof. It’s just plywood and tar paper. We have had lots of rain. Will this be a problem in the future and why has he not shingled it yet?
As long as the tar paper doesn’t get ripped up it will be fine. Even if the paper or felt is damaged it can be repaired or replaced and a little water on the plywood won’t be a problem long term.
