01 / Heritage
Clay that has outlasted its roof
Clay tile can outlast the layers beneath it. Sound clay can often be lifted, set aside and laid again, so the look of the house stays the same.
What it does to the price
Underlayment renewal
Much tile work is renewing the layer beneath the tiles; its extent sets most of the cost.
Coastal exposure
Flashing and fastener choices matter more near the ocean.
02 / Under the tile
What wears out is mostly hidden
Underlayment, battens and flashing do the waterproofing. They age with sun, slope and exposure, and they are where most tile roof estimates spend their money.
What it does to the price
Fire hazard mapping
Canyon and hillside areas may fall in mapped fire hazard zones with added requirements.
City or county permit
Incorporated cities and the county each publish their own permit fees.
03 / Coast and hills
Salt air below, fire maps above
Near the ocean, metal flashing and fasteners take the wear. In the hills, mapped fire hazard zones can bring their own roof rules. Both belong in a written estimate.
What it does to the price
Tile supply
Matching an older tile profile can limit options and add cost.
Roof form
Pitch, height and the number of valleys and penetrations shape the labor.
