Many San Marino properties carry a covering chosen for price rather than climate, and it shows in how early it fails. This holds across Los Angeles County.

Realistically, flashing at the wall junction is checked soonest on any San Marino inspection, given that that is where the majority of ceiling stains originate. We see it on San Marino roofs every week. On most jobs, core samples settle the argument on a San Marino low-slope roof when moisture is suspected but not visible. Granule loss in the gutters is the earliest honest signal on a San Marino shingle roof covering, and it shows up years in advance of a ceiling stain does.
