About Our Shingle Roofing Service
A shingle roof only performs as well as the system beneath it. We install the full assembly — synthetic underlayment, self-adhering membrane in valleys and at penetrations, galvanized or copper flashing, starter course, hip and ridge caps, and balanced intake/exhaust ventilation. That complete-system approach is what unlocks the 50-year non-prorated manufacturer warranties most contractors cannot offer.
Best For
Traditional and transitional homes across Chula Vista, Santee, El Cajon, Escondido, and Oceanside; budget-conscious full replacements; homeowners who want the best value-per-year of roof life.
Our Process
We inspect decking after tear-off and replace any delaminated or rotted sheathing before underlayment goes down. Every nail is pattern-placed per manufacturer spec — the single most common cause of premature shingle failure and voided warranties in San Diego.
Warranty
GAF Golden Pledge, Owens Corning Platinum, and CertainTeed SureStart PLUS warranties up to 50 years non-prorated, plus our own workmanship warranty.
Frequently Asked Questions
How much does a shingle roof cost in San Diego?
Architectural shingle replacement in San Diego typically runs $6.50–$11 per square foot installed, including tear-off, decking repair allowance, synthetic underlayment, flashing, and ridge ventilation. Every estimate we issue is fixed-price.
How long does an asphalt shingle roof last in San Diego?
Architectural shingle in San Diego's mild, high-UV climate typically lasts 25–35 years. Coastal homes see slightly shorter service life from salt air; inland homes lose life to heat cycling on south and west exposures.
What is the difference between 3-tab and architectural shingle?
3-tab is a single-layer flat shingle rated 20–25 years. Architectural (dimensional) shingle is laminated in multiple layers, carries higher wind ratings, and lasts 25–35+ years — we install architectural exclusively.
Can you install a new shingle roof over the existing one?
We do not recommend it. A layover hides rotted decking, adds dead load, voids most manufacturer warranties, and shortens the new roof's life. Full tear-off is the standard on every California First Roofing shingle replacement.
Are shingle roofs cool-roof and Title 24 compliant?
Yes — GAF Timberline Cool Series, Owens Corning Duration COOL, and CertainTeed Landmark Solaris are CRRC-rated and meet California Title 24 cool-roof requirements for San Diego permits.
How long does a shingle re-roof take?
Most single-family San Diego shingle re-roofs finish in 2–4 working days including tear-off, decking repair, installation, and full site cleanup with magnetic nail sweep.
Do you repair shingle roofs or only replace them?
Both. We repair wind-lifted shingles, failed pipe boots, cracked mastic at flashings, and localized leaks — with fixed-price repair proposals and no trip charges anywhere in San Diego County.
What wind rating do your shingle installations carry?
Properly nailed architectural shingle with starter course and sealed ridge carries 130 mph wind ratings — well above what Santa Ana wind events deliver inland at Ramona, Alpine, and Poway.
