“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're very up-front about what everything is going to cost, so there are no surprises. We had to have pretty much the full roof replaced, with the exception of a few shingles, and it was pretty reasonable. I had five different estimates, and they were the best ones. They had awesome quality, and they beat everybody else out with the warranty too. I'd give them an A+.”

Review by
02/15/2018

“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.”

Review by

“My roofing was done with Certified. So far it looks good. Everything is going good; I have no complaints. Even my friends are—nobody's complained, it looks like. They did a full roof replacement. They removed it and put the new one in. I can give them an A. Everything's very nice.”

Review by

“They were wonderful. They were probably ten other roofs around the same time my roof was done, and my roof looks better than any others. They're A+.”

“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.”

“Well, 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.”

Review by
09/20/2016

“I mean, they did exactly what they were supposed to do when they were supposed to do 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 but call me back in ten years and then I'll let you know for sure. They did good. It was a real good experience.”

Review by

Review by

“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 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.”

Review by
09/06/2016

“Well, 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+.”

Review by
09/06/2016

“They were excellent. They did everything they said they were going to do and their communication was excellent, their work crew was very good, so really strong experience. They replaced an existing roof on a 25-year-old house. I would give them an A+.”

Review by
09/06/2016

“The foreman in charge of the job as well as the fellow that we talked to about the original, like the employees, they were great. That's probably the easiest way to say it. They replaced a roof for us. I'd give them an A for sure.”

Review by
09/06/2016

“They did a really good job and they had a very competitive price and all of their workers were quite competent. They did they replaced a large porch roof and did some gutter and siding work. I would give them an A+.”

Review by
09/06/2016

“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.”

Review by
09/06/2016

“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, 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.”

Review by
09/06/2016

“First of all, the salesman who I spoke with assured me that there would, that he would be on the job the day that the job was going on, he wasn't. And second of all when I got there instead of taking off the entire roof, which is what they were supposed to do before they put the new roofing down, they were fixing to put the new roof over top of the old roof without taking the other one off so that in turn made me not trust them and therefore I had to spend the entire day there overseeing the job. I guess I'd give them a D.”

Review by
09/06/2016

“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 - I can't quite remember which. 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, but the additional things in terms of the service part was very good. They did a roof replacement. I'd give them an A+.”

Review by
09/06/2016

“They did good quality work. They did a roof, soffit, flashing, eaves, fascia board - roofing and carpentry work. I was just going to add painting onto it too, because they did a nice job on painting up what they put in and making things look good. It would be a B or a high B. They were pretty good, but they had little problems we had to work with. They did try to do some things that they weren't experienced in and did badly. We corrected that, they corrected it, and came up with a good product.”

Review by
09/06/2016

“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+.”

“They did what they said they'd do and I had some concerns after they were done and they came back and repaired them. They replaced my roof. I appreciated their customer service. They were very responsive. I had to call them back and they came back and repaired them. I'd recommend them if a neighbor asked about the company. I'd give them a B.”

Review by
07/30/2014

“They redid my roof. The owner was responsive to all of my questions, and they always returned my phone calls or emails in a timely fashion, which I appreciated. I didn't really ever have to call customer service, so everything went great. I have already recommended them to my neighbors. I would give Certified an A.”

Review by
07/30/2014

“They're good. It was a good price. They did a good job. We had a little problem, and they responded to it nicely. They replaced the entire roof. We did have to call them back, and they fixed it promptly. We've referred them to many neighbors. I would give them an A-, because I'm a tough grader.”

Review by
07/29/2014

“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.”

Review by
07/29/2014

“Certified put a new roof on for us. The customer service was great—no problem. I think I'm going to have them do some more work, so I've had them back out for an estimate. We've recommended them to other neighbors. They get an A.”

Review by
07/29/2014

“Certified put a new roof on the sunroom. They explained to me what they thought the problem was, and it has not been leaking since they fixed it. I think the customer service was fine. They did a good job, and I would recommend them—A+.”

Review by

“They got everything done right the first time. They had a good price. Their customer service was fantastic. I didn't have to call them back for any problems. It was complete, and everything's good. I'd definitely give them A+.”

“Certified did roofing work for me. They came on time, they were efficient, and they got the job done in the time that they specified. The supervisor answered any questions I had, and there haven’t been any problems, so I would say the customer service is good. I would definitely recommend them. I’d give them an A.”

Review by
07/29/2014

“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.”

Review by
07/29/2014

“I liked that the owner was really laid back and very knowledgeable. He answered all of our questions and was really willing to work with us doing whatever we needed to have done. There was a little bit of a mistake on the bill, but they corrected it immediately. I heard about Certified through our homeowners’ association, and I would recommend them. I would give them an A.”

Review by
07/29/2014

“I liked the sales presentation. I thought it was honest, straightforward, and they didn't pressure me. They installed a roof, siding, and shutters. The customer service was good. It was very good. I didn't have to call them back, but right at the end of the project, they did a little bit of damage. They did make it right. There was a language barrier with the crew. That is about the only thing I didn't care for. It was hard to communicate with the crew. I'd recommend them to a neighbor if asked. I would give them an A-, because the capping on the siding where it connects to the roof wasn’t fully described to me. They did make it right, but they needed to explain that a little bit further. That's the only reason I would give them an A-.”

Review by
07/29/2014

“They did a good job, and they were very professional. The customer service was very good—it’s a good company. The owner is very conscientious. I’d give them an A+.”

“Certified was prompt and courteous, and their customer service was great. I didn’t have to call them back for any issues. I would highly recommend them—they get an A.”

Review by
07/28/2014

“They were straightforward, easy to work with, respectful crew and easy estimate. The customer service was pretty good. I thought they were good. They put on a new roof. They had to come back because the roof was not entirely level and not all the rainwater was flushing off the roof. It's a flat roof so they had to come back and do a bit of repair. When I had to call them back they were mostly respectful and were able to get somebody out fairly quickly. If a neighbor asked me about them I would say that I recommend them but they still were not able to fully resolve the issue of rainwater not flushing off the roof entirely. So, I've heard different things about whether all the rainwater should come off of a flat roof and so the installation is a little unclear to me, whether they did that perfectly or could have done it better.”

Review by
07/28/2014

“Certified was the most straightforward. We got three quotes when we were redoing our roof. They ended up being the most expensive, but they also offered a warranty, and they worked with us. They were really great. We originally thought we didn't need a new skylight, and somebody came the day before we were doing the whole installation, took a look, and brought it just in case the next day. They sent us photos while they were on the roof. It was totally an up-sale, but it didn't feel like it. They said, ‘Actually you do have a leak. It's not bad now but it could get worse,’ and so we ended up getting a new skylight. But if he hadn't come the day before and kind of done that extra work ahead of time, they could have just done an average job. I have recommended to several folks. I did have to call them back. They sent us an invoice and the pricing was not what we agreed to. They were like, ‘Oh yeah, sorry about that. We'll send you a new one.’ It was a deal and all. I would give them an A.”

Review by
07/28/2014

“I would have preferred they'd done better. They didn't do a great job of cleaning up afterwards. I was finding nails and debris in my yard for a month afterwards. They did a new roof for me. The customer service was pretty good. They seemed to be responsive and actually contacted me when I was delayed in getting a response back to them. I think I picked a color that wasn't available for shingles and I had to call them back. I think I would recommend them if a neighbor asked about the company. I would give them a B+.”

Review by
07/28/2014

“They explained everything quite well and gave us a good price. They did the work on time, and we haven't had any problems since. The customer service was very good. They did sort of a mixture on the roof. They put down some new tar paper and sort of redid what should have been done when the condo was built. I didn't once have to call them back for any problems encountered. I would recommend them. I would give them an A.”

Review by
07/28/2014

“I was not happy with them. They made a big mess, and then afterwards, one of the shingles on the top was open to the environment for a while. It took them like a month to nail it back in. When I called them back, the company said they would get to it when they could. They did not offer anything to make it better. They put on a full new roof. I guess I would give them a C-.”

Review by
07/28/2014

“They were a subcontractor to the general contractor so I didn't have much interaction with them other than they did a good job. They put a new roof on for me. We had one leak but they came back and fixed it. I'd recommend them. They did a good job. I would probably give them B+. There were some slight issues but other than that, they were fine.”

Review by
07/28/2014

“This was one of the best experiences I’ve had with a contractor. The foreman was absolutely terrific. He taught me a lot, and I was able to monitor the installation closely. It was perfect. I’d give Certified an A+.”

Review by
07/28/2014

“I had a balance, and they never haggled me about the balance. They let me pay it along in moderation. They were on time, they're very professional, and they sent me cookies. I would refer them to anyone who needs a roof built. I didn't have any problems or any reason to call them back for anything. I would give them A+.”

Review by

“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 installed a new roof and some new skylights. They did an awesome job. I would recommend them to anybody. They are great people to work with.

Review by

“They did roofing replacement. I think they have good work but had a couple of issues including the office. I was kind of disappointed when I had some questions after they installed the roof. I had some questions. It's part of the work. I can have doubts. But I am satisfied with their work service but I will not use them again. I would say a B. I wouldn't recommend them to a family member or a friend.”

Review by
09/03/2013

“They did everything—removed the old roof, replaced whatever boards needed to be replaced, and did gutters, downspouts, and those kind of things. They were the most responsive. 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+.”

Review by
08/30/2013

“I had a new roof done, and I think the installation happened in May. 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.”

Review by

“Certified installed a new roof. Once the guy wrote up the quote, they just came out as soon as I was able to schedule it. They did the work in one day, and they did a nice job of installing it and cleaning up. The time frame the work was finished in was good. The workers were friendly and very nice, and I thought the customer service was good. I was really happy with the roof, and hopefully it lasts as long as they say it will. I'd say they get an A+.”

“Certified did our roof, and it was excellent. The folks who actually did the roof did a really nice job. They replaced the roof and the gutters, and they had it done in a day. The gentleman who came out and gave me the estimate was very informative and answered all of my questions, so it was very good. Everything has held up excellent. I’d give the company an A+.”

“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.”
