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