Real feedback from homeowners who trusted JC Roofing and Gutters with their roofing projects.
"We got three bids for a roof replacement and JC Roofing was the middle price but had the best warranty and most thorough inspection report. The estimator spent 45 minutes on our roof documenting everything with photos. Installation crew was fast and respectful of our property. Very happy with our choice."
"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."
"Wind damage tore off the ridge cap and lifted shingles on two slopes. Called on a Saturday morning and had someone out by noon to tarp it. Permanent repair was scheduled for Monday. Fast, professional, and the repair is seamless — can't tell where the new shingles meet the old ones."
