Saint Mary Roofing & Maintenance has replaced 235+ roofs across Saint Mary and Montrose, Piedmont, Rutledge, Theodosia, Windyville. Every replacement starts with a full tear-off and decking inspection. We find the damage the old roof was hiding, fix it, and build a new system designed for MO weather conditions.
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.
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.
Expert Installation
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.
Final Walkthrough
Three magnetic nail sweeps, during tear-off, after install, before we leave. Dump trailer hauled off. Job site clean. You approve the work and we register your manufacturer warranty on the spot.
