Honest reviews from homeowners who chose JC Roofing and Gutters for their roofing needs.
"Had soffit and fascia damage from water backing up under the roof edge. They replaced the rotted sections, installed new drip edge, and re-shingled the first three courses. Thorough work — they addressed the cause, not just the symptom. Area has stayed dry through several heavy rains since."
"We bought a fixer-upper and the roof was the first priority. The inspection revealed the decking was solid but the shingles were at end of life. Full tear-off and replacement with 30-year architectural shingles. Crew was fast, clean, and the foreman caught a ventilation issue that the home inspector missed. Fixed it during the install at no extra charge."
"Had an emergency when a large tree limb fell on our roof during a thunderstorm. They came out that evening, removed the branch safely, and tarped the damaged area. Full repair including new decking and shingles was completed by end of the week. Our insurance covered it and they handled all the coordination."
