San Joaquin Roofing & Maintenance has replaced 253+ roofs across San Joaquin and Hamilton City, Laguna Niguel, Mendota, Ontario, Rancho Mirage. 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 CA weather conditions.
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
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
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.
Professional Crew
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 San Joaquin homes finished in one day.
Inspection & Cleanup
Our project manager inspects the finished roof against the manufacturer checklist. You get a written workmanship warranty from San Joaquin Roofing & Maintenance plus the manufacturer warranty registered directly with GAF, Owens Corning, or CertainTeed.
