What does the San Gabriel climate do to a flat roof?
The San Gabriel climate is hot in summer with little marine cooling, so roofs heat up fast and cool overnight, working flashings loose over time.
The city's restaurant density means grease is as big a threat as weather, since exhaust fans deposit it on every dining plaza roof.
How often should a San Gabriel commercial roof be inspected?
A San Gabriel commercial roof should be inspected twice a year, spring and fall, and every quarter at restaurant exhaust fans.
Dining plazas with many tenants accumulate curb and grease damage between visits, and an unchecked grease pool can ruin a section of roof in a single summer. Our commercial roof inspection page explains what each visit covers.
