Labor. California roofers earn a median $30.58/hr (BLS OEWS, May 2025) against a national median of $26.65/hr. Our California rates adjust the national dataset by that difference, applied to the labor share of the job.
Weather and code. Wildfire zones push Class A fire-rated assemblies; Title 24 cool-roof rules apply in many areas.
Licensing. California roofers hold a C-39 Roofing license from the CSLB — verify it before hiring.
The invisible stuff. Decking replacement ($65–$95 per sheet, installed) and extra shingle layers are only fully countable after tear-off — which is why every number on this page is a range, and why our satellite estimate shows its imagery date.
