"I had a great experience with clear view roofing and construction. They repaired my roof and painted it, and the results look amazing. The whole process was smooth from start to finish, and the team did high-quality work while keeping everything clean and organized. Robert was especially outstanding. He was extremely professional, knowledgeable, and easy to communicate with. He took the time to explain what needed to be done, answered all my questions, and made sure the job was done right. It’s clear he takes pride in his work and truly cares about customer satisfaction. I highly recommend this company to anyone who needs roofing work or painting done. If you get the chance to work with Robert, you’ll be in great hands!"

"So happy that you recommended his services. Alejandro was amazing and just finished doing our garage roof. He worked during the heatwave and never complained and did an "amazing job" and always with a smile. Also the clean-up was done so impeccably nothing left behind; just wonderful work. Alejandro also took the time to get everything we needed to get the permit and passed without any problems. We are so happy with the end product and so happy that we hired Ongoing Roofing, Inc would highly recommend their services."

"Once the crew did the repair and were paid, a couple of days later, the roof leak exactly at the same spot started. They never even sent me a contract, work order or invoice. The business owner just contacted me, responded to my complaint and identified the main leak cause and spot. They re repaired it at no cost. I appreciate his professionalism and care to work harder to fix the leak. He took time to explain the situation. I am convinced that they were not at fault first time around and Jesse kept his promise."

"After calling at least 10 different roofing companies, I was starting to lose hope. Every company seemed to give me the runaround, telling me I needed more and more work, & it felt like they were just waiting to open up the roof so they could keep adding charges. The whole process felt like a scheme. Then found California Building Professionals, the experience was completely different. They responded quickly, came out to inspect my roof, and explained exactly what needed to be repaired—no scare tactics, no upselling, and no unnecessary work. They gave me an honest estimate, and throughout the entire project, there were absolutely no surprise fees or added costs. They showed me step by step everything they were going to do. The quality of their work was outstanding, and they delivered exactly what they promised. This has been the best experience I've ever had with a roofing company. It's hard to find contractors you can trust, but CBP earned my confidence and business for life!"

"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."

"Wow! An honest contractor who responds immediately. After looking at my concrete situation, he identified the problem and recommended a quick, inexpensive DIY solution. Great to see honest, sincere people still are out there."
