Lifespan
Concrete and clay tile can last 50+ years. Architectural asphalt shingles typically last 25–30 years in California climates. Tile usually outlasts the underlayment beneath it, which is why tile homes often only need an underlayment replacement rather than a full re-roof.
Cost
Asphalt is significantly cheaper upfront. Tile costs more to install but spreads the cost over a much longer service life — often a lower lifetime cost per year.
Weight and structure
Tile is heavy. Most California homes built in tile-friendly eras can carry it; older homes built for shingles may need structural review before switching to tile.
Aesthetics and HOAs
Many California HOAs require tile or specific tile profiles. Always confirm HOA requirements before choosing material.
