"I have only positive things to say about Rhinos Roofing, Miguel and his crew. Miguel is very easy to work with and professional. The price was reasonable. His crew worked tirelessly and did a great job on my very steep roof. Miguel also put insulation and an attic fan in the attic, which makes such a difference in the temperature upstairs! They were on time, pleasant, neat and always closed the gate to my backyard so my dogs wouldn't get out. I got quotes from other roofing companies, some that were more expensive and did not pay attention to details like that. I highly recommend Rhinos Roofing."

"Pablo and his crew know what they're doing. Our standing-seam metal roof looks great! They showed up on-time every day, worked hard, fixed problems that were discovered and left us with a beautiful roof. It was obvious from their bids that many other roofing contractors didn't really want to install metal. Ontop gave us a fair quote - and backed it up with great workmanship."

"I needed to get my roof repaired due to the high winds. A lot of shingles had flown off and I did not want to go through the water damage experience again. I reached out to Atom builders and they sent out their project manager, Mike. He was the best there is and thoroughly explained the entire process. The roof was done in 1 week and it looks magnificent. I highly recommend Atom Builders to anyone looking to get their roof replaced or repaired"

"I had Ocean Seven Builders replace a roof on my primary residence along with a rental property of mine. They knocked out the work at my house in one day and were done by 1pm on the rental property. They were prompt and showed up first thing in the morning and did a lot of prep work to make sure there wasn't any debris falling on my deck table or in my air conditioner. They contacted me once during the day to confirm the color of two vents. I stopped by at lunch and they answered all questions, etc. When I came home in the evening from work they were leaving and they did not leave any trash, nails, etc at all. The roof looks great after the work was completed. I would hire them again."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Angwin, CA

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
