Tile roofing (clay or concrete) offers unmatched longevity (50-100 years), Class A fire resistance, and a distinctive Mediterranean or Spanish aesthetic that is popular throughout Northern California. Installation includes structural verification (tile is heavy at 9-12 lbs/sq ft), tear-off of existing roofing, underlayment with battens, tile laying with wire ties or screws, and custom flashings at all penetrations and transitions. Concrete tiles are the more affordable option while clay tiles offer superior color retention and a premium look.

Tile's thermal mass helps buffer NorCal's extreme summer heat, keeping attics cooler than lightweight roofing. The gap between tile and deck provides natural ventilation that improves energy efficiency.

Antioch is located in Contra Costa County (East Bay). Delta city with affordable newer housing developments. The local utility provider is PG&E.

California Building Code

California Building Code requires tile roofs in seismic zones to be mechanically fastened (wire-tied or screwed) rather than mortar-set. Structural capacity must be verified per CBC Table 1607.1. Tile roofing inherently meets CA Title 24 cool-roof requirements.

Project Timeline

Structural Verification & Tear-Off

1-2 days

Verify the roof structure can support the weight of tile (900-1,200 lbs per square). Remove existing roofing material, inspect and reinforce decking as needed.

Underlayment & Batten Installation

1-2 days

Install self-adhering underlayment across the entire deck. Snap chalk lines and install horizontal battens at the correct exposure for the tile profile.

Tile Installation

3-5 days

Load tiles onto the roof in balanced stacks. Lay tiles from eave to ridge, securing with wire ties or screws per seismic requirements. Flash all valleys, penetrations, and wall transitions.

Ridge, Hip & Cleanup

1-2 days

Set ridge and hip tiles with mortar or dry-ridge systems. Install bird stops at eaves. Clean all debris and schedule the final inspection.

Tile Roof Installation in Antioch — FAQ

How much does a tile roof cost in NorCal?+

Concrete tile roofs cost $15,000-$28,000 for a typical Sacramento-area home (20 squares). Clay tile runs $25,000-$45,000+. The higher cost is offset by a 50-100 year lifespan with minimal maintenance.

Can my house support the weight of a tile roof?+

Tile weighs 9-12 lbs/sq ft vs. 2-4 lbs/sq ft for asphalt. Homes originally built with tile can typically accept a new tile roof. Converting from shingles to tile may require structural reinforcement, which adds $2,000-$5,000.

Are tile roofs good for California wildfires?+

Yes. Clay and concrete tiles carry a Class A fire rating and are among the most fire-resistant roofing options available. They are recommended for homes in WUI zones throughout NorCal.

How long do tile roofs last?+

Concrete tiles last 50+ years and clay tiles can last 75-100 years. The underlayment beneath the tiles typically needs replacement at 25-30 years, but the tiles themselves are reusable during the re-underlayment process.
