"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."
"They replaced our roof after a recent hail storm. The new roof looks better than the original. Manuel patiently showed us all options and we ended up with a much better match. When they came back it was one of the hottest days of the year and it didn't diminish their professionalism. They didn't leave until we were 100% satisfied. Highly recommend."
"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."
