What does the Irwindale climate do to a flat roof?
The Irwindale climate hits flat roofs with foothill heat, dust from nearby quarries and strong Santa Ana winds coming out of the San Gabriel Mountains.
Fine mineral dust grinds into membranes and packs drains, and winds strong enough to lift perimeter flashing arrive several times most fall and winter seasons.
How often should an Irwindale commercial roof be inspected?
An Irwindale commercial roof should be inspected twice a year, spring and fall, and again after any strong Santa Ana wind event.
Wind damage at edges and flashings is the most common Irwindale finding, and it rarely leaks until the next rain. Our commercial roof inspection page explains what each visit covers.
