Certified Incorporated did an excellent job in replacing our cedar shake roof. Everyone with whom we dealt at the company was terrific. James made our choice of roofing company easy - he was extremely knowledgable, professional and responsive. Javier and his team were simply excellent. They were punctual, polite, considerate and as unobtrusive as possible, and cleaned up every day. We are very happy.

Super happy to have found Certified through a friend and neighbor who runs a home inspection service. Turns out other neighbors have used Certified and were very satisfied with their work.

Certified was excellent. While the job took longer than estimated (5 full days vs 1 day), there was a lot of work to do and the crews performed with the utmost professionalism and pride in their work. I am very happy with the finished product. The house looks incredible and we're so excited not to ever have to worry about rotten wood again! Thank you James and Thank you Certified!

It delayed the start while they waited for the new shakes, but in order to ensure that the job would be...Read more

The initial estimate went very well. James, the estimator, was punctual, informative, and friendly. We received 4 total estimates and Certified's product and pricing was very competitive. We chose Certified because they had the best warranty and were willing to price match our second best offer. We had a bit of an issue with scheduling, the initial work was scheduled for January 30th, and as the date approached, weather conditions were looking unfavorable. I was concerned with work being done in...Read more
