Alright, having a house built and I just happened to be down there while the roof was getting shingled. They had about half of the roof done when they realized it was the wrong color (this is when I got to the job site and told them it was wrong). Well they ripped off the shingles and were about to start with the correct ones when I stopped them. Seems they were going to reuse the felt paper which had become nail-ridden and torn up during the tear-off. Guy says they do it all the time and started to put up new shingles. I'm on the phone to the builder telling him whats going on and he says they will stop until it gets inspected. Never happens. By the time the builder gets on site they have most of the roof reshingled. Builder goes up on the roof with the roofing supervisor. Roofing super says its ok but my builder says maybe not. They agree to finish the roof since bad weather was called for soon. Builder re-emphasizes that the roof is warrantied for 15 years and the sub would be responsible for any problems. I ask him who pays for all my possesions that get ruined by a leaking roof? Before he could say my homeowner's insurance, I tell him that I will let insurance know about this situation, especially since its still in construction and easily fixed. They counter with a full tear off with new felt and removal of all previous nails etc. So after reading all of this my question is, is it better to just leave whats up alone and not risk all of the new nail holes, or would it be better to do the tear off and start with new paper and such? I am leaning to the latter but wanted some other opinions. TIA.
