"After noticing a leak in my ceiling, I called Confirmed Roofing Experts for a roof repair, and I’m so glad I did. Osh and his team arrived promptly, assessed the issue, and provided a fair quote. The repair was done quickly and professionally, and I haven’t had a single issue since. Their attention to detail and commitment to customer satisfaction truly set them apart."

"Adam arrived on short notice, and I was thoroughly impressed with his professionalism. We suspected roof damage and needed urgent help—he made time to come the same afternoon. Despite it being a free inspection, he carefully checked everything and provided honest, detailed feedback. He even sent a full set of rooftop photos at no charge, which was incredibly helpful since I couldn't inspect it myself. If I ever need a roof repair or replacement, I won’t hesitate to call him again. His honesty and integrity truly set him apart. Highly recommended!"

"We had a great experience with this company repairing our roof. They showed up on time, explained what was causing the issue, and gave us a clear idea of what needed to be repaired. The crew was careful, finished the work efficiently, and cleaned everything up afterward. The repair looks great, and we have not had any issues since. Overall, very professional and easy to work with. Definitely a 5-star experience."

"I had a leak where the garage roof meets the wall and i thought it must be in wall or that flat roof. But they quickly ruled that out and found the leak was under the tiles in the sloped roof above. They proved it to me by pulling off some tiles and showing me the deteriorated paper and wet plywood. Excellent diagnosis."

"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."
