Permit fees in Hayes Valley are a small part of the job and a large part of what protects the owner at resale.
Metal has grown in Hayes Valley for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. Worth knowing before you sign anything. Mixing materials across a Hayes Valley roof is fine provided each section gets the system it requires and the transitions are flashed properly. Tile is widespread across Hayes Valley, and the tile will outlive the underlayment beneath it by decades — which is what catches homeowners out. This holds across San Francisco County.
