In practice, we check ventilation on every Mission District project, because a roof that cannot breathe will not reach its rated life.
Put simply, a light-coloured covering in Mission District measurably lowers attic temperature and takes load off the air conditioning. Dry offshore winds reach Mission District through autumn, lifting shingle tabs and ridge caps in the direction roofs are least lapped to resist. Thermal cycling does the damage in Mission District — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year.
