What does the Long Beach climate do to a flat roof?
The Long Beach climate is coastal, with salt air, a regular marine layer and sea breezes that keep temperatures mild but corrode metal components quickly.
Buildings near the port also take industrial and diesel residue, which settles on membranes and in drains.
How often should a Long Beach commercial roof be inspected?
A Long Beach commercial roof should be inspected twice a year, spring and fall, with a focus on corroded metal drains, flashings and fasteners.
Port-side buildings corrode faster than those near Douglas Park, though both see marine exposure. Our commercial roof inspection page explains what each visit covers.
