Hot dry summers do most of the damage here, long before the first storm shows you the leak.
Fullerton has a hot summer Mediterranean climate, and that is the real adversary for a deck here. Months of daily heating and cooling work a coating loose at its edges and around every post and penetration. Nothing looks wrong. Then the first serious rain finds all of it at once, and the failure gets blamed on the storm rather than the summer that set it up.
Occupied housing splits almost exactly down the middle at about 50 percent owner occupied, so the work runs evenly between homeowner decks and multi unit walkways and stairs. Northern Fullerton has hillside ground around the West Coyote Hills ridge, where slope and runoff come into it as well.
