Tile is widespread across Hayes Valley, and the tile will outlive the underlayment beneath it by decades — which is what catches owners out. Mixing materials across a Hayes Valley roof is fine provided each section gets the system it needs and the transitions are flashed properly. San Francisco County is no different. On most jobs, lightweight tile gives Hayes Valley owners the look without the structural upgrade older framing would otherwise require.
