Roof replacement at Port Costa 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 Port Costa crews do this every day. Most homes are finished in a single day.
We carry certifications from GAF, Owens Corning, and CertainTeed, the three largest shingle manufacturers in the country. Our Port Costa crews are factory-trained and your roof qualifies for the best warranties available, including GAF Golden Pledge with 25-year workmanship plus 50-year materials.
Our Roof Replacement Process
Initial Assessment
Our Port Costa inspector examines every component: shingles, flashing, pipe boots, ridge vent, soffit intake, decking condition from the attic side. We share photos on the spot and give you an honest assessment.
Written Estimate
We email or text the proposal so you can review it at home. Material options, warranty details, project timeline, and one flat price. Questions? Call us at (877) 586-1316. We don't do high-pressure sales.
Installation Day
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.
