Our reputation is built on results. Here is what our customers have to say.
"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."
"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."
