Honest reviews from homeowners who chose JC Roofing and Gutters for their roofing needs.
"We had a skylight that leaked every time it rained hard. Got it replaced along with the flashing and surrounding shingles. The crew was meticulous about sealing everything properly. That was eight months and dozens of rainstorms ago — bone dry every time. Should have called sooner."
"Needed a roof inspection before our insurance renewal. The report was thorough — detailed photos of every section, estimated remaining life, and recommendations for minor maintenance. No pressure to do unnecessary work. That kind of honesty is refreshing. Will call them when the roof actually needs replacing."
"Our commercial building had a persistent leak that two other roofers couldn't fix. These guys found the problem on the first visit — a failed pitch pan around an HVAC penetration. Repaired it properly and we haven't seen a drop in six months. Sometimes you need someone who actually knows what they're doing."
