Sumner Roofing & Maintenance | Delaware Roofing Services

"Emergency tarping after a windstorm ripped our ridge cap off. Sumner Roofing & Maintenance had a crew out within three hours and tarped the exposed section before rain moved in. Saved us from interior water damage."

"What sold me was the inspection report. Detailed photos of every damaged area, measurements, written explanation of what needed repair versus replacement. No other company gave us anything close to that level of documentation."

"I called about a small leak and expected a hard sell on a full replacement. The inspector showed me it was just a cracked pipe boot — $300 repair instead of a $12,000 roof. Honest company."

No Subcontractors

Every Delaware roof is installed by our own trained crews, not subcontractors pulled from a labor pool. That means consistent quality, accountability, and a crew that knows our standards from the first nail to the last drip edge.

Manufacturer-Certified Installation

We hold certifications from GAF, Owens Corning, and CertainTeed. That means the manufacturers have trained and vetted our crews and will back our installations with their strongest warranties. Your Delaware roof gets factory-level quality control.

17+ Years of Experience

We've been installing and repairing roofs for over 17 years. That experience shows in how we handle complex roof lines, unexpected deck damage, and insurance claim disputes. We've seen everything and know how to handle it.

GAF Master Elite Certified

Only 2% of roofing contractors in the country hold GAF Master Elite certification. That gives Delaware homeowners access to the Golden Pledge warranty: 25 years on workmanship, 50 years on materials. It's the strongest warranty in the industry.
