A roof replacement is more than pulling off old shingles. At Grenville Roofing & Maintenance, we do a complete tear-off down to the decking, inspect every board for moisture damage or rot, and build your new roofing system from the deck up. Every layer installed to manufacturer specifications.
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
You receive a written proposal with material specs, labor breakdown, timeline, and total cost. We price by the square and itemize everything. Compare apples to apples with any other quote.
Professional Crew
No subcontractors. Grenville Roofing & Maintenance crews, Grenville Roofing & Maintenance equipment, Grenville Roofing & Maintenance supervision. A project manager checks in throughout the day and does a quality inspection before cleanup begins.
