Overall, the company did very well, even giving me a discount on the more expensive shingles without me asking. They cleaned up after themselves well, and left a minimum of nails on the ground. They were polite and professional as well. The only complaint I have is that the workers laid the shingles over the drainage holes in my gutter system in some areas, covering them and preventing the system from working as it should. I didn't notice it until a few months later. I called back and explained and asked them to come cut the shingles away from the gutters. I was assured that they would take care of it, but no one came. Once when it rained, the roof leaked around the chimney. I called and told them-and reminded them about the shingles on the gutters.
