As I said, this was a tough job. The roof was in rough shape because it had been previously painted with the wrong paint, so they sand-blasted it to bare metal and primer-ed it then followed with multiple coats. They had some trouble with defective paint, and high roof temperature, and they had to work around frequent summer rainstorms, but they kept at it and got the work done though it took a couple of months. I was well-satisfied at one point, but they felt it could be better so they came back and re-coated certain areas of the roof. they kept the jobsite as clean as possible (sand-blasting is a messy business) and their price were more than fair for the nature of the work.
