Roof types we see here

- Concrete tile
- Copper and sheet metal detailing
What the local conditions do to a roof
Mature tree canopy means heavy leaf load in gutters and valleys, and shaded slopes that stay damp longer after winter rain.

Common San Marino roofing questions
My house is original to the 1920s or 1930s and the tile still looks great. Is there anything to worry about?
Almost certainly the underlayment, not the tile. Clay tile genuinely lasts 50–75 years, but the waterproofing membrane beneath it typically fails at 20–25 years — long before the tile shows any sign of trouble. A roof that looks period-perfect from the street can still be leaking from a failed underlayment, and the fix is a lift-and-relay, not a new roof.
Can you match the tile or slate profile on an older San Marino estate?
Matching original clay tile, concrete tile, or slate profiles — including salvaged or reproduction stock where an exact match matters — is routine work on this housing stock. We tell you up front whether an exact match is realistic before we start.
Does San Marino require anything special for roof material changes?
San Marino runs its own building department, and street-visible material changes on an estate property are worth a conversation with the city before you commit, given the design expectations here. We confirm what applies to your address as part of the estimate.
What does the tree canopy do to a roof here?
Heavy leaf and debris load in gutters and valleys, and shaded slopes that stay wet longer after rain than an unshaded roof would. Both accelerate wear at valleys and around chimneys and skylights, which is where we look first on an older San Marino roof.
