"David from Clearview Roofing was fantastic in helping replace the roof at my daycare center. We had a huge leak, and he was incredibly speedy with the repairs. He took care of everything from A to Z, making the whole process smooth and stress-free. Highly recommend!"

"Our experience with Roofing Angels was second to none! We were dreading the thought of replacing our roof, thinking it would be a stressful, drawn-out process, but Daniel and his team made it completely hassle-free. From day one, the communication was excellent. Daniel kept us updated throughout, ensuring that we knew what to expect. The crew was professional, polite, and worked incredibly efficiently. They completed the entire roof replacement in a timely manner, staying on schedule despite some unexpected weather delays. What really stood out was their attention to detail. They didn’t cut corners and ensured every aspect of the installation was done with care. They also did an amazing job cleaning up—I was worried about finding stray nails in my yard, but they left the property spotless. The price was competitive, and the quality of their work speaks for itself. I would 100% recommend Roofing Angels to anyone needing a new roof."

"Work started on a Saturday with large experienced teardown crew. They completed teardown and started wood replacement where necessary. At end of the day they covered the entire roof with sheeting in case of rain. A small experienced crew returned early on Monday to complete the wood work. When city inspection was done on wood repair, they started the shingle work and finished in a few days. At the end of every day they went on a nail patrol with magnetic tools looking for nails around the perimeter of the house. They did a very professional job with roof, cleanup, etc. I used Hoyt before on another house and will use them again."
