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."
"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."
"We were dreading getting our roof replaced — everyone says it's the worst home improvement experience. It wasn't. The crew was courteous, communicated every step, and finished in a day and a half. They even put down tarps to protect our landscaping. The new roof transformed the whole look of our house."
