it has been cool and rainy all week and the roofers have worked around the raining...is it advisable to shingle a roof when the tar paper is wet and curled and the outside temperature is approx. 50-60 degrees for most of the day and drops in the 40's at night? the roofers tell me the water will find itself out and that it is okay...what do you say?
Not a great plan. They only get paid when there finished so there rushing it.
And just how do they figure the waters going to work it's way out once it's trapped under the shingles?
That's why sometime you will see shingles with blisters on them.
