"JC Roofing did a solid job on our roof replacement. Took about three days which was a little longer than quoted, but the finished product is excellent. They found some rotted decking that needed replacing and showed me before proceeding. Fair pricing on the extra work. Would hire again."
"After the hailstorm last spring, we had three roofers come out. JC Roofing was the only one who showed me exactly where the damage was instead of just saying I needed a new roof. Turned out we only needed repairs on one section. Honest company that didn't try to upsell me. That integrity earned a customer for life."
"My elderly mother needed her roof replaced and I was coordinating everything from out of state. JC Roofing made it easy — video calls to show me the damage, detailed written estimate, and they even moved her patio furniture before starting. The crew was respectful and cleaned everything up. Mom is thrilled with her new roof."
