A well-built wood patio cover can last for decades in Southern California when the finish is kept up. Sun, not rain, does most of the damage here, so plan to re-coat the stain or paint every few years, and sooner on south and west-facing exposures that take the most heat.
UV light breaks down an unprotected wood surface, which leads to graying, checking and small cracks. A good stain or paint applied to every face of the lumber, including the tops of rafters and beams, is what holds that off. Inland summers are hot, so covers in places like Murrieta, Temecula and Corona see more sun exposure than those near the coast. The top surfaces of an open lattice or rafter roof take the most direct sun and usually need attention first.
Construction details matter as much as the finish. Posts set on metal bases above concrete footings keep the wood off the ground and away from standing water, which helps prevent rot at the base. A solid roof needs slope and drainage so water runs off away from the patio instead of sitting on the framing. Metal connectors at the footings, beams and rafters keep joints tight, which matters in areas with strong Santa Ana winds.
Simple maintenance goes a long way. Look over the cover each year for faded or peeling finish, especially on the sunny side, and re-coat before bare wood shows. Keep sprinklers aimed away from posts and beams, and clear leaves off solid roofs so they drain. Choosing lumber finish, roof style and stain color with your exposure in mind at the design stage helps the cover hold up longer between re-coats.
