We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship and complete customer satisfaction, from the start to the completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"Premiere was absolutely amazing! Carlos did two projects for us - coating our house roof with silicone and coating our office building with silicone. He was so thoughtful and did such a careful job. The pipes coming out of the roof often develop cracks over the years so they double-coated them to make sure they were solid. One of the things my wife is particular about is cleanup after the job. They came in afterwards and pressure washed our deck and cleaned the pool to remove any debris so everything was spotless. Part of the quote is to come in once a year for three years and inspect the roof so we are confident everything will remain in good shape. AND they were very reasonable! I can't recommend Carlos and his crew more highly."

"If I could give a 10 out of 5 stars I would. Argo from Sandoval roofing came out and gave me a quote which was very reasonable. After getting a few more quotes, we decided to go with Sandoval roofing to completely redo our roof and patio (new sheathing, paper, and tiles). We decided to go with them because they were quick to respond through call and text (even late at night), gave a good price, are licensed and bonded through CSLB, and have roofers with 25+ years experience (their roofer Francisco was awesome) They were able to start within a week of giving the quote, and finished the whole job in 4 days. The two bosses were on site to overview the job which I appreciated as well. Overall I could not be happier with this company. With all the bad contractors there are now a days it’s hard to find someone who does quality work at a good price, but Sandoval roofing did so. Sorry for the ramble, but they finished my roof today and I’m very pleased with it so I thought I’d share my whole experience."

"I don’t normally write reviews, but I had such a great experience with Roofing Angels that I had to share. Chuck was amazing—from the first meeting, he made sure I understood everything about the process and helped me choose the right materials for my home. No pushy sales tactics, just honest advice. His crew was super professional and hardworking. They showed up early, worked long hours, and always made sure to clean up at the end of the day. I was expecting a lot of noise and disruption, but honestly, it wasn’t bad at all. Now that the job is done, I can’t stop admiring my new roof! It looks perfect, and I feel a lot better knowing I won’t have to worry about leaks anymore. If you’re looking for a stress-free roofing experience with people who actually care, I can’t recommend Roofing Angels enough!"
