On most jobs, a permitted Nob Hill re-roof leaves a record that supports any later insurance claim on the same roof. Unpermitted roofing in Nob Hill surfaces at resale. the San Francisco Department of Building Inspection keeps the record, and a buyer's inspector knows to look for it. Work in Nob Hill is inspected as well as permitted — the San Francisco Department of Building Inspection signs off the finished assembly, not just the application.
Attic temperatures in Nob Hill drive shingle service life as much as the weather above does, which is why ventilation matters more here than the brochure suggests. Put simply, nob Hill gets its rain in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. On most jobs, sealant is the earliest casualty in Nob Hill; it shrinks, cracks and pulls away from every penetration within a few seasons. It is the same story on most Nob Hill streets.
