Your roof protects everything underneath it, so when replacement time comes, you want it done right. Alleghany 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 Alleghany 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
Initial Assessment
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.
Transparent Pricing
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
Crew arrives at 7 AM with all materials pre-staged. Tarps go down to protect landscaping. Old roof comes off, decking gets inspected and repaired as needed, and the new system goes on layer by layer. Most Alleghany homes finished in one day.
Final Walkthrough
Our project manager inspects the finished roof against the manufacturer checklist. You get a written workmanship warranty from Alleghany Roofing & Maintenance plus the manufacturer warranty registered directly with GAF, Owens Corning, or CertainTeed.
