"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!"

"I had been putting off replacing my roof for a while, but after a particularly bad storm, I finally knew it was time. After getting a few quotes, we decided to go with Roofing Angels, and I’m so glad we did. Jonathan made the whole process really easy to understand, and I never felt pressured. He walked me through the options, and together, we decided on the best route. The team came in, got to work, and were done before I even realized it! The job was completed in less than a week, and the crew was awesome—very professional and careful about not disturbing our property. I was impressed by their work ethic and how they kept me updated without me needing to chase them down for info. The new roof looks amazing, and it’s so much more secure than the old one. The whole experience was so smooth that I actually feel bad for waiting so long to replace it! If you’re looking for a trustworthy, hardworking team that won’t cut corners, Roofing Angels is the way to go. Jonathan and his crew made everything happen seamlessly, and I couldn’t be happier with the result!"

"Very well. On schedule, efficient work crews, professional installers, project managers addressed any questions and concerns quickly and with resolution to owner's expectations, kept a clean work area after each day, no delay due to lack or back log of inventory. Bid was not the lowest nor the highest, but definitely matched the quality of product and work with no hidden or surprise costs. Would recommend without hesitation and invite anyone considering this company to come by and inspect the installation."

"We're thrilled with the work done by Platinum! They replaced our entire roof, and we couldn't be happier. The price was fair, and the quality of their work was an exactly what they mentioned to us when they first gave the estimate. We were so impressed that we've already decided to hire them for our family business's body shop roof. If you need roofing work done, these guys are the ones to call!"

"Very good experience with Newhaus. They did a flat roof/sundeck (rebuilding) the entire surface and they replaced the damaged ceiling underneath in a guest bedroom. Peter and Menoua were always very responsive, very supportive and absolutely reliable. Very nice and hardworking crew both for the roof and the bedroom ceiling restoration. Thank you."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Diamond Bar, 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.
