Columbia Roofing Contractor | Serving Columbia From Grandin

"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."

"Second roof Grandin Roofing & Maintenance has done for us. First one on our primary home, now our rental property. Same crew both times, same attention to detail. Drip edge, ice shield, everything by the book."

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