What does the Gardena climate do to a flat roof?
The Gardena climate is mild, with a marine layer on many mornings and a few miles of distance from the coast that keeps salt exposure lower than in Torrance or Redondo Beach.
Older roofs here fail mostly from age and ponding, since the dense stock of 1960s and 1970s buildings has had several recover layers added over the decades.
How often should a Gardena commercial roof be inspected?
A Gardena commercial roof should be inspected twice a year, spring and fall, with special attention to buildings that already carry two roof layers.
Recovered roofs can hide wet insulation between layers, which is exactly what a moisture scan finds and a visual walk misses. Our commercial roof inspection page explains what each visit covers.

Who issues reroof permits in Gardena?
