About Our Roof Replacement Service
A replacement is only as good as what goes on under the covering. We specify high-temperature synthetic underlayment, ice-and-water at valleys and penetrations, corrosion-resistant fasteners and flashing for coastal homes, and full ventilation correction — the details that decide whether the roof reaches 25 years or fails at 14.
Best For
Roofs past 20–25 years; repeated or multi-location leaks; homes being sold or refinanced; properties upgrading to tile, metal, or a cool-roof assembly.
Our Process
We measure the roof, document deck and ventilation condition, and present material options with fixed pricing. On install day we protect landscaping, tear off to the deck, repair wood at pre-agreed unit rates, install the new system, then walk the finished roof with you photo by photo.
Warranty
Manufacturer system warranties up to 50 years on qualifying assemblies, plus a California First Roofing workmanship warranty on the installation.

Frequently Asked Questions
How much does a roof replacement cost in San Diego?
Most San Diego re-roofs range from $12,000 to $45,000+. Architectural shingle typically runs $9–$14 per sq ft installed, concrete tile $15–$25, clay tile $20–$40, standing-seam metal $18–$32, and TPO $9–$16. Every proposal is fixed price.
How long does a roof replacement take?
A typical San Diego residential re-roof takes 2–5 working days. Tile lift and relay, larger custom homes, and structural repairs can extend that to 5–10 days.
Do I need a permit to replace my roof in San Diego?
Yes — re-roofing requires a permit in the City of San Diego and every county jurisdiction. We pull the permit, schedule inspections, and handle the final sign-off as part of the project.
Can you replace a roof over the existing layer?
Code allows a limited overlay in some cases, but we rarely recommend it: you inherit whatever is failing underneath and void most manufacturer system warranties. Full tear-off is what allows a 50-year warranty.
How do I know when my roof needs replacing?
Leaks in multiple locations, granule loss and bald spots, curling or cupping shingles, exposed felt in valleys, sagging planes, and any roof with original 25-year-old underlayment are all replacement indicators.
Do you offer financing for roof replacement?
Yes — we offer financing options with monthly payments, and we'll show total cost with and without financing so you can compare honestly.
Will you handle my HOA approval?
Yes. We prepare HOA architectural review packages including material samples, color chips, profile drawings, and manufacturer cut sheets, and we've submitted to most San Diego County associations.
What warranty comes with a new roof?
As a GAF Master Elite, Owens Corning Preferred, and CertainTeed SELECT ShingleMaster contractor, we can register manufacturer system warranties up to 50 years, layered over our own workmanship warranty.
