Our Roof Replacement Process
Initial Assessment
Our Grantham inspector examines every component: shingles, flashing, pipe boots, ridge vent, soffit intake, decking condition from the attic side. We share photos on the spot and give you an honest assessment.
Written Estimate
Our estimator builds your proposal same-day in most cases. Multiple material options at different price points: GAF, Owens Corning, CertainTeed, with warranty comparisons for each. No pressure, no expiration tricks.
Installation Day
No subcontractors. Grantham Roofing & Maintenance crews, Grantham Roofing & Maintenance equipment, Grantham Roofing & Maintenance supervision. A project manager checks in throughout the day and does a quality inspection before cleanup begins.
Inspection & Cleanup
We walk the property with you, show you the finished roof, and answer any questions. Magnetic nail sweep across the yard, driveway, and walkways. Gutters cleaned out. Your warranty gets registered that same day.
