Asphalt loses its oils, membranes lose their plasticisers, and sealant shrinks back from every flashing. Afternoon sun on a west-facing Potrero Hill slope ages that side years ahead of the rest of the roof. We see it on Potrero Hill roofs every week. Summer heat is the main ageing force on a Potrero Hill roof. Surface temperatures run far above the air reading, day once past day, for months.
Most Potrero Hill roofs that give out early fail at a penetration someone could have resealed for a few hundred dollars. This holds across San Francisco County. Resealing penetrations on a Potrero Hill roof every few years is the cheapest the project anyone will ever do on the building. As a rule, a Potrero Hill roof with working drainage outlasts an identical roof without it by years. Worth knowing before you sign anything.
