Certified was referred to us by a family friend and they did not disappoint. The team was very good at communicating and scheduling. Everything was done as we expected it and we could not be happier with the results.

Steve was very personable and his crew was on time, efficient, and professional. I would definitely recommend this company for their roofing expertise.

We were so pleased with Certified when they replaced our roof several years ago that we asked them to replace both our roof *and* our siding when we moved to our new house. They gave us a good price, explained the options well, and did quality work.

Crews were nice and neat. The replacement shingles and capping of the windows looks fantastic. They worked diligently on schedule. We highly recommend them to friends in the area. Thank you Certified for the good job.
