Honest reviews from homeowners who chose JC Roofing and Gutters for their roofing needs.
"Hired them for a metal roof installation on our workshop building. Standing seam in charcoal gray. The crew knew exactly what they were doing — proper underlayment, clean panel cuts, tight fastening. Building stays cool in summer and the roof sheds snow perfectly in winter. Zero maintenance two years running."
"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."
"Had a persistent leak around a bathroom vent pipe that two handymen couldn't fix. The roofing crew pulled back the shingles, found the old boot had completely cracked, replaced it with a proper lead boot, re-sealed and re-shingled the area. Took about an hour. No more leak. Sometimes you just need the right people for the job."
