Recommended Customer Reviews

In 2017, our flat roof in Aptos (tar and gravel) needed a replacement, and we wanted to use the Metacrylics coatings instead of stripping off the T&G. Metacrylics recommended Ceritfied Roofing, and we found them very knowledgeable and experienced in this type of roof. They gave us a reasonable bid, did a very nice and clean job, and finished in spite of inclimate weather on time. The roof has been thru a couple of winters with no leaks and looks great. There is some standing water in the winter, but the metacrylics coating doesn't degrade.

David and his crew delivered an excellent product with excellent service. It was a complete re-roof of a 2900 sqft single story with 4 valleys and 7 skylights. New sheathing along with the replacement of 5 skylights and an asphalt room was installed. I was also remote, as this is my home that I am currently renting while living on the east coast. David was extremely thorough in the project review, quote, and even assisted in my purchasing the skylights direct to save money. The job was completed on time and with great quality. 2 years after the completion, one of the solar skylights stopped working, and while not his responsibility, he had a person come out and take a look, It was a loose wire and he fixed the problem free of charge. I notice some not so great reviews on Yelp for Certified Roofing, and all I can say is that I find those hard to believe given my experience with David. I have no hesitation recommending him to my friends and will use him again for all my roofing needs.

Advise caution with this company. They installed a slurry roof for me. I was assured it would last 15 years. When I sold my house 18 months later it did not pass inspection. Certified Roofing caulked some spots for me but did not address the major issue, which was a large low area that collected standing water. The company refused to warranty the roof to new owners. I had to compensate buyers for the cost of an extensive repair.

This company came on a short notice to inspect the roof of a house. The inspector was friendly and gave a clear summary of all issues encountered, and provided recommendations. He uncovered lots of problems that translated in thousands of dollars of required repairs. The report they provided was informative, but we had to ask for it several times, and it was a simple email rather than a professional looking report that other inspectors provide. Still, the information reported and estimate are good.

Gutter Services, certifiedroofing.info :
Gutters and Downspouts were installed in a very timely manner as I had requested to expedite the job. David paid attention to my request to re-locate a downspout. He was open to negotiate payment plans. I wanted to support his small local business and he wants to treat you like a friendly neighbor.
The finished job is quality materials and currently have no problems with the gutters nor downspouts.

This is the most unprofessional company I have ever encountered. I am selling my house and called Certified Roofing for an estimate. I had one bid from another company and wanted another to compare.. George arrived on time and I immediately told him I had a roof inspection done and there were many broken tiles and I wanted an estimate to replace the broken tile. He asked to see the inspection report of the first contractor and I told him I'd rather he wrote his own report along with his estimate .
George very rudely asked me if "" I distrusted contractors and if I had a problem with them"".and whether I had a reason to not believe the first contractor. I than told him how the bidding process worked and just wanted to compare prices. George's quote to me was "" I think I will leave my ladder in the truck"" he got in his truck and rode off waving goodbye to me.
There are many good roofing contractor out there so why take a risk with one that doesn't have a clue and is rude to boot.
