Can’t say enough great things. Tim was an excellent rep and helped me navigate insurance and the process overall. They were on-time, fast, friendly, did a fantastic job and left everything spotless. They company checked-in on the day of install to make sure things were going smoothly, which they were. First time having to replace our roof so we were somewhat clueless about the process, options and next steps. Certified was patient and helped guide us without any pressure. Highly recommend them...Read more

Certified Roofing did a fine job replacing my 25 year old roof. Work done all on the same day. Came back a week later and Javier inspected the roof. Very efficient company.

great price and a 50 year warranty, including labor costs, through the shingle company (Certified doesn't even need to exist in 50 years). They sent a big crew, done in one day. I have a steep roof with gutters 30+ feet off the ground so not the easiest job. I brought the crew lunch from a local Mexican place and that seemed to motivate them even more.
