Winthrop Roofing Contractor | Serving Winthrop From Grandview

"Second roof Grandview 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."

"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."

"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."
