San Dimas sits where fire-zone assembly requirements apply, which limits what can be installed and how edges and vents must be detailed. Put simply, ember risk shapes roofing decisions in San Dimas: class A assemblies, closed eaves, and no gaps at the ridge where embers can enter. Debris load is heavy in San Dimas — needles, leaves and grit collect in valleys through the dry months and block them the earliest time it rains hard. Metal suits many San Dimas roofs since it sheds debris and meets fire assembly requirements without fuss. Put simply, vent screening is what decides it in San Dimas where ember intrusion is a real risk rather than a theoretical one.

Reclaimed tile can be matched on San Dimas heritage roof coverings, but the underlayment beneath it should always be new. As a rule, synthetic composite has become a credible option in San Dimas where the look of slate or shake is wanted without the weight or the fire risk. Put simply, cool-rated coverings are worth specifying in San Dimas even where code does not require them. It is the same story on most San Dimas streets.
