Our reputation is built on results. Here is what our customers have to say.
"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."
"JC Roofing responded promptly to our quote request. Arrived as scheduled for both estimate and installation. Professional in all interaction. We got quotes from 5 companies. They weren't the cheapest or the most expensive but they were able to schedule the job the soonest at a fair price. The work was completed in less than 4 hours and looks like it was part of the original build."
