What does the Commerce climate do to a flat roof?
The Commerce climate gives a flat roof long dry summers in the inland basin, heavy air pollution from freeways and rail, and short bursts of winter rain that test drains all at once.
Soot settles into seams and drains between storms, so the first heavy rain of the season is when Commerce roofs most often back up.
How often should a Commerce commercial roof be inspected?
A Commerce commercial roof should be inspected twice a year, spring and fall, with the fall visit timed before the first winter storm to clear drains and scuppers.
Buildings near the rail yard and freeways collect debris faster than most, which makes the pre-storm visit the more important of the two. Our commercial roof inspection page explains what each visit covers.
