Most tile leaks start at the metal, not the tile
Concrete and clay tile shed water onto the underlayment and into metal flashings. When a valley is packed with leaves, or a pipe boot has cracked, rain gets under the tile and travels. Pulling every tile on the slope is not the first step. We find the metal that failed, replace that piece, and relay the tiles we had to lift.

Questions about flashing leaks
Can flashing leak if no tiles are broken?
Yes. That is the usual Cerritos call. The tile is the cover. The leak is the metal or the underlayment at a joint.
Do you seal flashing with caulk only?
Caulk is not a flashing repair. The metal has to lap the right direction and the tile has to be relayed over it.
Which neighborhoods?
Cerritos Park East, Shadow Park, Greenbrook, Sorrento, and the rest of Cerritos tile roofs.
