"We are giving Hoyt Roofing a 5 Star rating, because of the excellent job they did on the installation of our new roof. The whole process only took four days and the workers went over and above to keep us informed of the progress and maintaining a clean work area. We were impressed from the initial meeting where we discussed and deciding on the terms and conditions to completion of the job. They were not pushy or try to upsell their products. We highly recommend this company to anyone who needs a new roof."

"Roofing Angels exceeded all my expectations! Jonathan and his crew were professional, polite, and extremely knowledgeable. From the initial inspection to the final clean-up, everything was handled seamlessly. Jonathan kept me updated throughout the entire process, ensuring there were no surprises. The work was completed right on schedule, and the craftsmanship is top-notch. I was especially impressed with how clean they kept the worksite—no nails or debris left behind, which was a big deal for us since we have kids and pets. Their pricing was competitive, and the quality of materials they used was excellent. Overall, a stress-free experience with a fantastic outcome. I highly recommend Roofing Angels for anyone in need of a roof replacement."

"We have a historic home and there was additional care required to replace siding beneath the roofing material at the eaves. The team at Jordan roof completed the entire job in only 4 days, they fixed up our dormer which had shingles that had deteriorated, and repainted some of the shingles. Our home looks better than ever! Great responsiveness, fair pricing, and high quality work."

"I had such a great experience, I felt like I needed to leave a review. We had an unexpected leak that turned into our kitchen having black mold all over. Our insurance company pretty much told us they were not responsible. Nathan was sent out and was very knowledgeable about what we were looking at. From, day one he was able to guide us through the process from mold removal to a complete kitchen remodel. Anytime I had a question or concern he was right there to help. Every single person that came to work in my house was friendly; not to mention on time which is a big plus. Everything turned out beautiful! I would highly recommend Home Renew 360. I would definitely higher Nathan again for future projects. I honestly can’t say enough about them! I am extremely satisfied."

"PVC team installed a new roof on our house June 2024. Their pricing was best value of all firms contacted and I felt comfortable working with them. They got the job done on time, actually a half day sooner. Our neighbors notice how well the guys worked, didn’t waste time. Quality of workmanship appears very good. I’m pleased with results, more importantly my wife happy, too. Jaime and the team at PVC are a solid family run business. -MS"

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.
