"I have been trying for a while to get my roof replaced. The weather recently damaged my roof more than it was before , so I had no other choice than getting a new roof. I had my roof serviced by Expert Roofing and it was the best choice I have ever made. I had a personal contact with Sean from the beginning to end. He was very helpful, he explained everything to details and was there for every step of the way. I would highly recommend them."

"Outstanding experience from start to finish. The team was professional, punctual, and clearly took pride in their work. Communication was excellent, the job completed on time, and the quality of the roofing exceeded expectations. I highly recommend them to anyone looking for reliable, top-quality roofing services!"

"Highly recommended! Adam Tweedy and his team repaired our 'cool roof' and three patio decks in just two days. The crew was efficient, careful with our furniture, and the installation was impressive. The roof passed the water test, proving its quality. An added bonus: they didn’t need to remove our solar panels, saving us time and money. For a reliable, water-tight roof at a reasonable price, call Reign Roofing!"

" California roof experts is a highly professional company. The first time I received a phone call, after requesting help from Angie’s list, they called and left a very nice message. I returned their call and we had a very nice conversation about what needed to be done. We arranged for an inspection/estimate and they were on time - they were very professional. They explained everything, they were not rushing me and it was a very nice experience. I felt very confident with them. After a second estimate from another company did not go well at all, we went ahead and went with california roofing experts. This was a metal roof of a mobile home that was very old and in need of a good cleaning and protection with sealant. They did an excellent - excellent job. They were on time and they were professional. We got pictures before and after and were amazed at the difference. We are so glad we chose them. And we’re glad they could work on a mobile home. Highly recommend"

"I never thought I'd describe a roof replacement as a pleasant experience, but here we are. From the start, Jonathan and the team at Roofing Angels were a breath of fresh air. We got multiple quotes, and Roofing Angels wasn’t the cheapest, but they were the most transparent and professional. Jonathan took the time to inspect our roof thoroughly (unlike others who barely looked at it) and explained why certain materials were better than others. I appreciated that he wasn’t just trying to upsell us—he genuinely wanted us to make the best choice for our home. The crew was incredible. They arrived early, worked efficiently, and kept us updated throughout the process. I loved how respectful they were of our space—our driveway and yard were spotless when they finished, which I can’t say for other contractors we’ve worked with in the past. Now, our house looks better than ever, and I actually feel relieved every time it rains, knowing our roof is rock solid. If you want a team that truly cares about their work, look no further than Roofing Angels!"
