Real feedback from homeowners who trusted JC Roofing and Gutters with their roofing projects.
"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."
"JC Roofing replaced the flat roof section over our garage. Communication could have been slightly better on scheduling but the work itself was top notch. No more leaks and the new membrane looks clean and professional. Fair price for the quality."
"Found water stains on our ceiling after a storm. The inspector went up on the roof and found hail damage across the entire south slope. They handled the full insurance claim and replacement. New GAF Timberline HDZ shingles look fantastic. The whole process from inspection to completion took about three weeks."
