HOMEOWNER REVIEWS SELECTED FROM SURVEYS COLLECTED:

“They were excellent. They did a nice cedar-shake roof on a small addition. They were terrific. I'd give them an A+. I loved the salesman. He'd worked for the National as an ex-baseball player turned roofing/marketing person. He was really terrific. They took on my rather small job. They do whole houses, and when we do our house with the shake roof, we'll use them. This was a kitchen addition, but the whole house is going to have to be redone. I thought their salespeople were good. Sometimes, there's a disconnect between sales and actual folks that come out. The roofer was really wonderful, the guy who did the work. He was terrific. He'd been with them for 15 years. They were seasoned. They were all great. There were two roofers, and then the salesperson who gave me the estimate. They were all terrific. I'll use them again. It's hard to find people who really do—the owner of the business does—we have a cedar roof. He has this type of roof himself. I feel like they really knew what they were doing. I would highly recommend them.”

“They showed up when they promised and completed the work on schedule. I would give them an A.”

“The owner got a little testy with me toward the end, but I was happy with the work. He just felt we had a difference of opinion, and I'd had a positive expert, and I was sorry to see it. I just walked away from my complaint and tried to end it on a happy note. They did roofing work for me. I was 95% happy with it. They worked hard. They were in and out. They did what they needed to do and all that. I'd give Certified an A. I have no major leaks so far. I'll give them an A-.”

“They did what they said they were going to do, and they did when they said they were going to do it for the most part. There were delays, but they weren't catastrophic delays. They were easy to work with. I'd give them an A-. They did a nice job.”

“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'd say it was an A+. They were very professional. They completed the job better than ever expected and they followed through with what they said.”

“It was a good experience.”

“We got a great rate, and it was during the winter, so when there was inclement weather, the foreman came back after nine o'clock to reinforce the temporary cover for our roof. They were replacing our roof, but they have to cover it at the end of the day, and it was properly sealed before he left. He came back in the evening to make sure it was properly sealed because there was rain in the forecast in the evening. I'd give them an A. I think, with a caveat, I probably should have gotten a home inspection or roof inspector to make sure they did a proper job. I don't think I ever got an actual warranty after the work. That's the only thing, and I never followed up on that. I have no way of telling about the quality of work. That's the problem. It's just like going to the dentist, I don't know. I haven't had any leak issues. Visibly it looks fine. For the siding, I would give them an A, because visibly, it looks great.”

“They did a great job. The responsiveness of their customer service and the quality of the work stood out. It was siding actually, and it was a replacement and gutters too. I'd give them an A.”

“They replaced our roof. There were a couple of hiccups in the process like the wrong shingles were delivered. They fixed everything, didn't have any problems, and didn't delay the work. I'd give them an A.”

“I'd give them an A.”

“It was a while back. I would give them an A.”

“I'd give it an A.”

“It was a complete roof replacement. I grade it an A.”

“They did a very thorough job, and often it seemed that they just went above and beyond normal standard service to make sure that we were pleased and happy. We have a flat roof, and they completely replaced the entire roof. I'd give them an A.”

“I don't know if he's like a sales guy or who he is that came by, but he was very responsive and helpful. They put a new roof on our house. I'd give them an A.”

“They did exactly what they were supposed to do when they were supposed to do it, and that's kind of unusual for contractors nowadays. They put some new skylights in for me and a roof and gutters. I'd give them an A. They did good. It was a really good experience.”

“They did roofing work for me, and they were great. They did a very good job. They did it for the price they said they would, they cleaned up, and it took the amount of time that they said it would. They tore off the old one, put in a new one, and added a skylight. I'll give them an A.”

“Certified put on a brand-new roof. They are very professional, and they did a great job with it. I thought their customer service was excellent. I had a hatch to my roof that they covered, and I was concerned that it would be an issue, but when I called them, they came right back out and fixed it without any problems. I'd highly recommend them. I'd give them an A.”

“They were prompt and on time, and they did everything correctly. I heard about Certified through my neighbor. They did three houses in our neighborhood. The customer service was excellent, and I did not have to call them back for any problems after the work was done. They're A+.”

“They were on time, they did a great job, and they cleaned up nicely. I heard about them when they were doing a bunch of stuff in the neighborhood. The customer service was fabulous—I had no issues or any reason to call them back for anything. Everything worked great. Certified gets an A.”

“Certified did a whole new roof for me. I liked their willingness to come over to the house to talk to us and look at our roof more than once. They were willing to talk out different options and approaches, and they did frequent updates during the work and afterward. I thought the customer service was very good. They're an A.”

“They did a roof for me. They were very responsive and completed their work quickly, and their customer service was very good. I didn't have to call them back for any issues after the work was done. I'd give them an A.”

They came out and were excellent and very, very knowledgeable. They know their stuff. When the time came for scheduling, the scheduling was quick and on time. They continually followed up, making sure that I was ready. They gave me a date, and that date was set. Several guys were on-site, and they finished my roof entirely. It was excellent manageability—so much so that I recommended them to other people, and they did the same thing. A+.”

“They put a new roof on, and everything matched up perfect. I give them an A+.”

“Certified was wonderful. They put a roof on. We had no problems at all with the workers—they were polite and did their job, and we didn't have to clean up after them. I would rate them an A+.”

“I had a very positive experience with Certified. They replaced my roof in its entirety, and everything has turned out fine. It's only been a couple of months, but one of the reasons I went with them was because of the type of warranties they offered. I'd give them an A- for an extremely slight issue, which involved cleanup and was resolved, that would kind of prevent me from giving them an A+.”

“They came in and did what they needed to do. They seemed to do a good job, seemed to be flexible, and seemed to be good about dealing with some of the unusual requirements. It was done maybe three months ago, and everything seems to be holding up great. I chose three or four companies, and Certified was the one that was able to do the work I wanted.

On the day of the installation, I wasn't physically there, but I went through the process of having the estimate and the communication with the representative at the company. Everything went smoothly. On the day of the installation, from my understanding, it went rather quick and efficient. We haven't had any issues as far as the installation goes. I personally haven't gone out on the roof, but having said that, I would grade them an A. The cleanup was good, as well, for the most part. There was one piece that they may have not seen, but it wasn't a big deal for me, at least.”

“They did roofing work, and it was great. This was the first time I used them. They left minor stuff, but I didn't really care—I just wanted the roof fixed. I saw the workers, and they were OK. I didn't converse with them, because most of the time they were here, I wasn't here. I'd rate them an A.”
