Licensed Roofer Serving New Castle, DE

"Had a bad leak around the chimney flashing after a storm. Delmar Roofing & Maintenance came out next day, found the failed step flashing, replaced it, and sealed everything properly. No more dripping. Solid work."

"Our flat roof on the garage had been patched five times by other companies. Delmar 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."
