Licensed Roofer Serving Greenwich, CT

"Their crew showed up at 7 AM, tore off the old roof, replaced eight sheets of plywood, and had new shingles down before dinner. Jobsite was cleaner when they left than when they arrived."

"They replaced all our gutters along with the roof. Seamless aluminum, properly pitched. Water actually drains into the downspouts now instead of overflowing at every seam. Night and day difference."

"Our flat roof on the garage had been patched five times by other companies. Cornwall Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."
