Your roof protects everything underneath it, so when replacement time comes, you want it done right. Markham Roofing & Maintenance removes the existing roof completely, examines the decking for water damage, and installs a new system from underlayment through ridge cap. Every component matters.
Our Markham replacement crews install GAF, Owens Corning, and CertainTeed shingles. We carry manufacturer certifications from all three, meaning factory-trained installers and access to the best warranty programs available. We help you choose based on budget, color, and warranty goals.
Our Roof Replacement Process
Comprehensive Evaluation
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.
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. Markham Roofing & Maintenance crews, Markham Roofing & Maintenance equipment, Markham Roofing & Maintenance supervision. A project manager checks in throughout the day and does a quality inspection before cleanup begins.
Final Walkthrough
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.
