“They're very, very good. The people that worked were extremely courteous, and they were extremely good about cleaning up every day after their work. They were here two to three days. It was impressive compared to many of those service people that I've had in the last ten years. Their job was very good. They delivered as expected, so I'm very happy with the roof. And the additional things, in terms of the service part, was very good. They did a roof replacement. I'd give them an A+.”
“They were excellent. They did everything they said they were going to do, and their communication was excellent, their work crew was very good, and so it was a really strong experience. They replaced an existing roof on a 25-year-old house. I would give them an A+.”
“They're the best. Just everything made it positive. They were great. I would grade it the best overall, A+. Everything was A+. They're the best.”
“It was all positive. Certified, they did a great job on everything. They had excellent work with no complaints.”
“It was a more difficult job than originally anticipated, but they were able to resolve that themselves and didn't require any contract. They just took care of it, basically. It was a roof rip off and reinstallation, as well as gutters. I'd give them an A+.”
“They have a really quick response time as far as any questions that I had. They got the job done. They were putting the roof on actually fairly quick, within about a week, so quick turnaround especially considering it was starting to get into their busy season. The roof replacement was the total scope of the work they did for me. I'd give them an A+.”
“I was happy with the work. They did a roof. It was a replacement. I'd give them an A+.”
“I had a positive experience. I'd give it an A+. They did clean up. It's just that I have a little debris in my attic. But I guess that wasn't their fault.”
“I had a positive experience. I would give it an A+.”
“I grade it an A+. It was the whole roof.”
