Your roof protects everything underneath it, so when replacement time comes, you want it done right. San Gregorio 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.
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
Initial Assessment
Our San Gregorio 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
You receive a written proposal with material specs, labor breakdown, timeline, and total cost. We price by the square and itemize everything. Compare apples to apples with any other quote.
Professional Crew
No subcontractors. San Gregorio Roofing & Maintenance crews, San Gregorio Roofing & Maintenance equipment, San Gregorio Roofing & Maintenance supervision. A project manager checks in throughout the day and does a quality inspection before cleanup begins.
Warranty Activation
We walk the property with you, show you the finished roof, and answer any questions. Magnetic nail sweep across the yard, driveway, and walkways. Gutters cleaned out. Your warranty gets registered that same day.
