"Great price, lower than other companies quotes. Doesn't add on work you don't need. They actually fixed my roof the very next day as they were able to move their schedule around to accommodate. Highly recommended."

"the strong winds ripped a lot of my tile roof. Sean and Josh were quick to react ! they came to inspect the roof and explained me with photos they took what happened on my roof . they came the next day with the worker to install new tiles and performed maintenance on the roof. thank you for the quick response !!"

"I can't recommend Reign Roofing enough! They completed our steep roof project in just one week, and the quality of work is excellent. After receiving quotes from 10 other roofers, Reign Roofing stood out for its professionalism, reasonable pricing, and transparency. Our insurance (USAA) was difficult, offering only half of the replacement cost, but Reign Roofing worked with them to submit a detailed estimate and get our roof fully covered. We’re grateful for their hard work and help navigating the insurance process. Thank you, Reign Roofing!"

"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 needed our old roof replaced and got a few quotes from different roofing companies before we chose California Building Professionals. They were the only ones that explained the roof replacement process, answered all our questions, and made us feel comfortable with the project. GREAT COMPANY!"

"Mr Cisneros was efficient and went over and above fixing the roof. He cleaned up the pine needles that were thick on the roof as well as fixing the seams and flashing around the chimney."
