I chose a reputable roofing contractor who has been around over 50 years and comes highly recommended. I am questioning a few things:
Day 1: they ripped off one full side of the roof, replaced all the plywood (it was all in bad shape) and nailed down felt paper.
Day 2: they didn't show up due to rain in the forecast, but there was no rain, and they could have gotten all the shingles down over that dry felt paper if they were here.
Day 3: it rained lightly overnight and continues to rain lightly. They are now nailing the shingles over the wet felt paper.
They tell me it is no problem if the felt is wet, the heat of the sun (whenever it comes back) will dry it. But I have read that it is not a good idea to lay shingles in damp or wet weather. Am I wrong?
I am also a bit concerned that they left the shingle packages outside and some were ripped partially open, so that some of them will be wet at the time they are installed. I am using CertainTeed Landmark 30 year alphalt shingles.
Are there any risks from installing the roof in this weather? It's also a bit cool (49 degrees). Is there anything to look for when the job is done that could be a sign of trouble? Should I put something in writing when signing off on the job to indicate my concerns?
