On most jobs, a light-coloured covering in National City measurably lowers attic temperature and takes load off the air conditioning. We see it on National City roofs every week.

Streets in National City that were built out together tend to need roof coverings together, which is why one re-roof often brings three more on the same block. Roof covering pitch across National City varies enough that the right material on one street is the wrong one two blocks away. That is as true in National City as anywhere in San Diego County. On most jobs, many National City properties carry a covering chosen for price rather than climate, and it shows in how early it fails. It is the same story on most National City streets.

Concrete tile suits National City buildings designed for the weight; laying it on framing that was not is a structural question soonest. In practice, tile is widespread across National City, and the tile will outlive the underlayment beneath it by decades — which is what catches owners out. This holds across San Diego County. Cool-rated coverings are worth specifying in National City even where code does not require them.
