What SoCal Roofs Need
What Southern California Climate Demands From a Roof
Most of Southern California shares four things — high UV, low rainfall, occasional Santa Ana winds, and varying salt-air or fire exposure depending on location. A roof here has to handle all of that, not just rain.
UV Resistance
Sustained sun exposure ages shingles faster than rain ever would in SoCal.
Wind Resistance
Santa Ana wind events test ridge, eave, and nailing pattern quality.
Coastal Salt Resistance (where applicable)
Coastal homes need corrosion-resistant flashings or fully synthetic systems.
Fire Rating
Class A fire rating is essential in much of Southern California — both GAF systems and DaVinci synthetic carry Class A.
