Clay and concrete tile roofs are everywhere in San Jose, Los Gatos, Saratoga and Santa Clara. The tiles themselves last a long time, but the underlayment underneath wears out much sooner, and a few cracked or slipped tiles are enough to let winter rain into the attic. Titanium Roof Innovations repairs, resets and replaces tile roofs across San Jose and the South Bay, and we tell you honestly which of the three your roof needs.
