"Cornerstone was spot on from beginning to end. Starting with the estimator to the job clean up. They were very thorough & professional. I requested a specific time frame and they were more than accommodating. The first day went like clockwork with the crew showing up right on the quoted time and the dumpster showing up within 5 minutes of the crew. Tear off was done in a day, shingles were delivered and stacked on the roof that same evening and the job was completed the next day.
Two skylights were also replaced and are beautiful. I watched several houses in our neighborhood take at least 3-4 days. The project was completed with a roof inspection a couple of days later and I couldn't be happier. I got estimates from six companies and Cornerstone was who I felt most comfortable with. The whole experience was excellent and I would recommend them to anyone."

I had a great experience with everyone from CSR. The quote was completed promptly and was very thorough with clear explanations of the work to be completed (including pictures). A team member came to the house to show us roofing samples. We then drove to a few homes that had the same roofing material that we wanted to confirm our selection. The CSR roofing team was super efficient and professional; in and out in two days.
During the final inspection, Juan took his time walking me around the new roof and answering my questions. He even pointed out some chimney work that I needed to have done and answered some questions about siding maintenance! Great experience all the way around!

James represented the company very well. He gave us option to help with Certainteed claim and quoted us the roof replacement cost based on what the job required. He did not see replacing material that did not need to be replaced. Other companies quotes were not this way.

We had Cornerstone roofing replace our roof in the summer of 2020. They were excellent from start to finish. We also recently had them come back and patch an old sewer vent that our plumber never took care of. They did a great job, quickly patched the area, and were very reasonably priced. They also replaced our gutters. We couldn't be happier with their service!

CSR installed a new roof on our home in June 2021. Their customer service and sales people were outstanding, and the roof itself is great, though we're still "proving" it now that we're in winter. The foreman for the job also very kindly refinished a porch-ceiling board that we thought was rotten but just needed some surface fixes. We really appreciated that. We ran into some issues with the installation crew (disposal of old roof materials and unused supplies, broke a flower pot and damaged our rose bush, etc.), but the company quickly addressed this issue with me when I had posted about it (and to be fair, I neglected to bring it up with them privately at the time).
They issued us a gift card to compensate for the damage, and said they would address the issues with their install crew. I appreciate their prompt response, and am satisfied with their promise to prevent such issues in the future. Thank you.
