As a rule, flashings at the chimney on an older Granada Hills house usually need attention well before the covering does. Converted garages in Granada Hills are a common source of leaks because the roof was never upgraded with the conversion. Drainage is the cheapest maintenance on any Granada Hills building — blocked outlets cause more deterioration here than the storms themselves. Resealing penetrations on a Granada Hills roof every few years is the cheapest the job anyone will ever do on the building. This holds across Los Angeles County.

A Granada Hills property often carries more than one roof type — a pitched main house in one material and a flatter garage or addition in another. A Granada Hills roof covering with working drainage outlasts an identical roof without it by years. Attic temperatures in Granada Hills drive shingle working life as much as the weather above does, which is why ventilation counts more here than the brochure suggests. Roof surface temperatures in Granada Hills routinely run well above the air reading, and every material on the roof feels it.

Tile underlayment in Granada Hills dries out and goes brittle while the tile above it still looks new from the street. Put simply, summer heat is the main ageing force on a Granada Hills roof covering. Surface temperatures run far above the air reading, day once past day, for months. This holds across Los Angeles County. Realistically, streets in Granada Hills that were built out together tend to need roofs together, which is why one re-roof frequently brings three more on the same block. Put simply, clearing the Granada Hills gutters in late autumn prevents most of the damage the earliest storm would otherwise cause. It is the same story on most Granada Hills streets.
