At the time I was never more pleased with a job. They cleaned up after themselves and they showed up on time. Subsequently, I have wanted them to check the roof out. They were a little delayed in coming out. We realized one of the exhaust vents was not properly sealed and was leaking. They did come back out and fix it though.
Description of Work: They tore off our old roof and put a new one on about 8 or 9 years ago.

Overall, I would like them 9.5 out of 10!! No deposit was requested. I was not asked to confirm my Angie's List membership and they wrote up the discount without the coupon. The master shingler took off his shoes before coming into the house, and he was not asked to do that. He described the process, the warranty, the materials, the time it would take, and provided a comparison table where I could compare Certified to other estimates. I completed the comparison table on my own, signed the contract the next day, materials were delivered to the house and the roof, and if it were not raining, the job would have been completed before Labor Day. When I called the other companies to let them know they were not picked for the job, they tried to discourage me by bad mouthing Certified. I'm glad I did not accept that. My roof looks very good, and the heavy rain we had on Sept. 5 and 6 tells me that the roof and skylight are good. One last thing, Certified offered 2 free sheets of plywood if they found the present wood to be in bad shape. The other 2 companies would have charged $55 for each replacement board used, and I needed two. Thanks to Certified.
Description of Work: Needed a new roof, and added ridge vents. It had been raining for 2 days, but on Saturday morning (Aug. 30, 2008), 6 or 7 workers showed up to start the job before it rained that day. The clouds cleared and they were able to finish most of the roof until they ran out of shingles. They also did not have my replacement skylight, and the foreman said he did not know about a skylight, but would return on Tuesday (Sept. 2) to finish the job, with the skylight. On Tuesday they completed the roof but the skylight was the same. I emailed Tom K. on Wednesday and called the office on Thursday. I was told they had to order a skylight and that by the time I got home Thursday evening, the new skylight would be installed. It was and the roof looks fabulous. I also liked Tom's suggested color of slate gray.

The experience with them was great. They came in and furnished me with enough information. They answered my questions. They were very informative. They were professional. They finished the job in a timely matter, that's exactly what they told me. I was impressed with the contract we signed because it spelled out everything that they were going to do.

They were here within five days of placing the order, and finished the job in one day. They did a great job. I really liked that they let me pay with my credit card through the receptionist. They never asked me for a down payment. And they sent me a gift card after the work was done.

I dealt mainly with Tom who was extremely responsive to my request for a quote. There was no pressure or sales pitch - just straight talk and an understanding that I would shop a few other companies. I decided to go with Certified based on outstanding recommendations, their reputation for quality work, the warranties: 20 years on the roofing materials, 10 on the labor, and price. The team of roofers kept a consistent pace and did a great job of cleaning up before leaving. A month ago I knew each day of the week the weather forecasters predicted rain, now I don't really give it much thought other than to be grateful that I don't have to worry myself over possible mold issues, rotten wood or falling plaster.
Description of Work: I had been experiencing intermittent leaks in my guest bedroom for over a year. The first company did a highly-questionable job. To add insult to injury they allegedly came back to my home a year later (while I was at work) to re-coat my flat roof. They didn't schedule the visit and never left a door tag, lawn flag or voice message as proof of their service -- but did bill me several hundred dollars. My decision to go with Certified was one I made very cautiously over a period of about a month of research and comparison. Certified removed the existing flat roof down to the decking, installed a 1" insulation board to the roof, applied a base sheet, a membrane and a second (granular) membrane.

We were happy with them. I think they did a really good job in terms of fixing everything and putting the roof on and it looks good. It's holding up a couple of years later.
Description of Work: They stripped off three layers of existing shingles, repaired a few holes in the roof, and they put on new shingles. They tore down the old gutters and put on new gutters with gutter guards.

I talked with 3 roofing companies based on Angie's List recommendations. I felt comfortable that I would get good service from all, but this company stood out in pricing and its professional approach to the job. The contract laid out all of the work they would do and left very little for me to question. They were at the house on time, were careful in their work, and left no signs of having been there but a great new roof. The roofing was done with two infants snoozing a floor below. My only little issue was whether they have the best gutter guard system. But it was right priced for our needs. I would also be sure to ask for the gutters to be flushed before adding any gutter guards. (I didn't ask them to do that but it probably should have been raised.)
Description of Work: Replaced roofing and made some repairs to hole and rotten wood. Added gutter guards as well.
