They did an excellent job except for when we developed roof nails in our tires. They tried to blame us and would not cover it. We don't have roof nails around our house. They tried to say that we had nails around our house. That may or may not be the case, but we do not have roof nails around the house. They did not want to take care of it. That is a serious problem. They don't stay involved after they get their money. Other than that, everything was excellent. They were on time, did what they said, and they stayed there the whole time. It leaves a bad taste in your mouth when you end up with roof nails in your tires. We had expenses because of it, and they said that it was not their problem.
