"I highly recommend Diamond Ridge Roofing Systems they did an excellent job for us. They responded quickly, answered all of our questions and understood our concerns. They are professional kind and courteous and solved all the issues we had after a tree fell into our house. They inspected the whole roof and replaced all necessary materials needed on the roof and eves and gutters. They even reported and repaired unrelated issues. They removed all debris and came back to inspect the job and make sure we were satisfied."

"Very responsive and always polite. Crews did a careful job removing the roof, keeping noise to a reasonable level, installing and cleaning up. The only down was an unplanned increase in the amount of replacement wood needed but perhaps that cannot be fully anticipated before seeing the state of the roof. Very good service, they handled everything."

"Facing urgent roof replacement due to my insurance non-renewal and a wildfire zone deadline, I turned to Lifetime Roofing & Renovations. Project Manager Marcelo M. was instrumental, guiding me through every step and assuring timely completion despite the rainy season and busy roofers. He communicated effectively with my tenant, earning high marks for clarity, courtesy, and follow-through, including cleanup. Marcelo oversaw the installation of a composition shingle roof and TPO fire-retardant material, meeting my insurance fire safety requirements. He provided photos that expedited my insurance renewal. I am very grateful for the efficient, high-quality work, praising Marcelo M.’s knowledge, kindness, and clear communication as invaluable to the company. A retired engineer friend approved the contract. Minor document errors from Sales Manager Brad Kenny were quickly corrected, prompting my suggestion for administrative support to improve efficiency."

""Hey there, just wanted to share my experience with Platinum Roofing & Retro-Fit.They did a solid job on our metal roof. The team was friendly and made sure we knew what was going on every step of the way. Our roof's looking sharp now! Also, when it started raining unexpectedly, they came out and tarped the roof to avoid any extra damage. If you're looking for roof work, they're worth reaching out to. Thanks, boys!"

"I highly recommend DS Roofing! I needed a new roof for my detached garage. The old roof had multiple layers of old roofing and was in poor condition. DS Roofing came out and gave me a fair price for the job. The owner was very helpful and informative, answering all my questions. Once I selected the bid, the crew showed up within a few days and tore off the old roof and installed the new one very quickly. What impressed me the most was how clean the ground was after all the debris that fell during the removal process."
