Quick question regarding roofing. Our builder came out yesterday and put up the tar paper on the roof. Because they showed up so late (after noon......despite a promise they'd be here by 8 am) they were not able to get the shingles up....instead, there is only tar paper up. I asked if there would be a problem if it rained on the tar paper and they claimed that it would be fine. Of course, with all the lies we've been getting from this builder (this barn was supposed to be done in early September after all) I don't want to trust him on his word in this matter. So......guess what? It rained last night. So.......will we wind up with troubles or am I being a worry-wart?
