Most roofs in San Jose can be repaired for years after the first leak, and a few need replacing sooner than the owner expects. The decision turns on four things that a technician reads on the roof and in the attic: the number of layers, the state of the deck, the condition of the flashings and the record of storms the roof has already passed. This guide sets out how each is read, and gives no price, because none can be given before the roof is seen.

Los Gatos and Saratoga sit in the Santa Cruz Mountain foothills south-west of San Jose, and Redwood Estates is an unincorporated redwood-forest community in the same hills. Roofs in these places sit under trees and on steep slopes, and the trees, the shade and the slope together wear a covering faster than an open roof on the valley floor.
