Barnstead Roofing & Maintenance | Grantham Roofing Services

"The Golden Pledge warranty was a big factor in our decision. 25 years on workmanship plus 50 on materials. Barnstead Roofing & Maintenance is one of the few local companies that can even offer it."

"Hail punched through half our shingles last spring. Barnstead Roofing & Maintenance handled the entire insurance claim — met the adjuster, filed the supplement, and we paid nothing out of pocket besides the deductible."

"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."

GAF Master Elite Certified

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

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 Grantham roof gets factory-level quality control.

No Subcontractors

Every Grantham 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.

Free Inspections & Honest Estimates

We don't charge for inspections and we don't pad estimates. If your Grantham roof needs a repair, we'll tell you. If it needs a replacement, we'll explain exactly why. No high-pressure sales, no scare tactics.
