I would not use them again 3 hours late the first day not even a phone call. Numerous no shows no calls I had to clean up the nails and roofing ever day before I could let the dogs out. The porch roof leaked first rain they came back to look and left came back chalked some still leaks they only used 3 screws per panel the wind blew several roof panels off.a number of roof shingles had to be replaced the first month because of cracks l had to chalk some nails they left exposed.I could go on but you get point.
