Many El Cajon properties carry a covering chosen for price rather than climate, and it shows in how early it lets go. Put simply, converted garages in El Cajon are a common source of leaks because the roof covering was never upgraded with the conversion. We see it on El Cajon roofs every week. Second-storey additions in El Cajon create a junction between old and new roof covering that requires proper flashing rather than sealant. We see it on El Cajon roofs every week.
9Why El Cajon Roofs Age the Way They Do
Afternoon sun on a west-facing El Cajon slope ages that side years ahead of the rest of the roof. Debris in El Cajon valleys holds what little moisture arrives against the covering, which is where rot usually starts. El Cajon gets its rain in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. Attic ventilation on a El Cajon property is not optional — trapped heat cooks the covering from underneath. Attic temperatures in El Cajon drive shingle life as much as the weather above does, which is why ventilation matters more here than the brochure suggests. Tile underlayment in El Cajon dries out and goes brittle while the tile above it still looks new from the street.
Granule loss in the gutters is the earliest honest signal on a El Cajon shingle roof, and it shows up years before a ceiling stain does. That is as true in El Cajon as anywhere in San Diego County. A proper El Cajon inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb fail long in advance of the covering does. Worth knowing before you sign anything. As a rule, lifting a few tiles in two or three places is the only way to date the underlayment on a El Cajon tile roof covering, and it takes fifteen minutes. It is the same story on most El Cajon streets.
