What does the Signal Hill climate do to a flat roof?

The Signal Hill climate is coastal and breezy, with the hill itself catching more wind than surrounding Long Beach, so perimeter flashings here see steady wind stress.

Salt air a few miles from the harbor corrodes metal components, and oil field activity can deposit residue on nearby roofs.

How often should a Signal Hill commercial roof be inspected?

A Signal Hill commercial roof should be inspected twice a year, spring and fall, with a focus on edges and metal flashings.

Buildings on the upper slopes catch more wind and corrode faster than those at the base. Our commercial roof inspection page explains what each visit covers.
