San Marino is estate housing from the 1920s–40s — Mediterranean and Spanish homes with clay tile, English Tudors with slate, and Colonials with wood shingle — on large lots with a design review process that protects the city's character. The roofs are big, often 80–100 years old, and their original underlayment and flashings are long past their life even where the tile and slate remain sound.
Tile and slate lift-and-relay with new underlayment and copper flashing, design-review submittals, and fire-rated replacements for aging wood shingle are the core of our San Marino work.
