Lightweight tile gives San Francisco property owners the look without the structural upgrade older framing would otherwise need. Worth knowing before you sign anything. Realistically, reclaimed tile can be matched on San Francisco heritage roofs, but the underlayment beneath it should always be new. Realistically, coatings suit San Francisco buildings with a in good order deck and a tired surface — they buy years, but they do not fix water already trapped in the insulation.
