As a rule, many Outer Mission properties carry a covering chosen for price rather than climate, and it shows in how early it fails. Converted garages in Outer Mission are a common source of leaks because the roof covering was never upgraded with the conversion.

9Choosing a Covering in Outer Mission
Reclaimed tile can be matched on Outer Mission heritage roof coverings, but the underlayment beneath it should always be new.
