They were great. I had a leak in my roof that nobody was able to fix. I had about three different roofers out there. They all claimed to fix it, but then the leak started again. The technician from Certitude came out, found the problem right away, and was able to fix it. They also did my garage roof. I'd give them A+.
They replaced a whole roof on the garage. They're on time. They were fast and good. I mean, they did a perfect job. I'd rate them as an A+.
Certitude was fabulous. I'd give them the highest rating.
They did an excellent job. It was an excellent experience—very positive. I would refer Certitude to anyone.
They did a great job. They were very professional and did the job very quickly. They cleaned up. No complaints.
They replaced my entire roof and a couple of boards. They were quick and really efficient. They did a really good job. I haven't had any problems with the roof since they did the job and I haven't had any complaints.
Everything was fine. I didn't have any complaints. Everything was good.
I had no complaints.
It was a while ago. I can say that it was very positive and they were great.
They did a good job. They did gutter helmets. They did good work. They did the work I was looking for. I'd say it was an A.
