Chimneys, vents, skylights and the swamp cooler curb fail long before the covering does. Granule loss in the gutters is the earliest honest signal on a Diamond Bar shingle roof covering, and it shows up years ahead of a ceiling stain does. This holds across Los Angeles County.
The project in Diamond Bar is inspected as well as permitted — the Diamond Bar building department signs off the finished assembly, not just the application. Unpermitted roofing in Diamond Bar surfaces at resale. the Diamond Bar building department keeps the record, and a buyer's inspector knows to look for it. Realistically, reroofing over existing layers in Diamond Bar is limited by code, and the layer count is checked at inspection.
