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