When your Alstead home needs a new roof, Alstead Roofing & Maintenance handles it from start to finish. We strip the old material to the deck, check for soft spots and rot, replace any compromised sheathing, and install a complete roofing system designed to last 30 years or more.
Our Roof Replacement Process
Free Roof Inspection
We climb up, walk the entire roof, and take photos of everything we find. Shingle condition, flashing, vents, gutters, and signs of moisture damage underneath. You get a full written report, free, no obligation.
Your Detailed Proposal
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.
Professional Crew
Our crews average 8+ years experience each. Tear-off, decking inspection, ice and water shield, underlayment, drip edge, starter strip, field shingles, hip and ridge caps, and ridge vent, installed in the correct sequence per manufacturer requirements.
Inspection & Cleanup
Our project manager inspects the finished roof against the manufacturer checklist. You get a written workmanship warranty from Alstead Roofing & Maintenance plus the manufacturer warranty registered directly with GAF, Owens Corning, or CertainTeed.
