"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."

"They replaced cracked tiles, and replaced the underlayment on leaking area with good rubberized material. Reset a lot of tiles that just moved from the wind. Sealed around all vent pipes. They done more than I expected."

"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."

"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!"

"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."

"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!"

"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"

"My project was for new roof n gutters, I had to have my old 3 layers of shingles removed. The team that demolished old roof shingles did a good job. Although it was a messy task, plastic sheeting was laid down n all material was disposed off. New plywood was laid down, there were a couple of spots that the plywood was not laying completely flat n was addressed. New shingles were installed in 2 days n look great. For the new seamless gutter install, the existing fascia needed painting but Newhaus wanted an extra 4,000.00 dollars to do it. So I hired a separate painter to do it for less than half the price. The gutters proposed were not the style I wanted n had to have them switch to what I wanted. The new gutters were installed n look great. Overall I am satisfied with the quality of the work n materials used although there were a couple leaks at corners that has to be re-sealed. However dealing with Newhaus could have been better, upon signing the contract online I did not hear from them for over a week to let me know the status or when work would start. I had to text the original sales guy to ask what was going on. The were also a couple of times workers did not show up when scheduled or were late from time that they were supposed to show up."

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.
