Roof replacement at Diablo Roofing & Maintenance means a clean start. We tear off everything to bare decking, inspect the entire surface for damage, and rebuild using manufacturer-approved materials at every layer. Our Diablo crews do this every day. Most homes are finished in a single day.
Material selection makes a real difference. We install GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark, all architectural shingles with Class A fire ratings and 130+ mph wind warranties. We walk you through the options so you pick the shingle that fits your budget.
Our Roof Replacement Process
Comprehensive Evaluation
Before we quote anything, we inspect everything. A 30-45 minute walkthrough of your entire roofing system. If you only need a repair, we tell you. If replacement makes more sense, we explain why.
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.
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.
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.
