Alameda County roofing licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 194 active C-39 roofing licenses in Alameda County, 22 of them registered in San Leandro. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median San Leandro license has been held 16 years, and the longest-standing one dates to 1959. California law requires workers' compensation cover for C-39 licensees, so it is a legal baseline rather than a way to tell two contractors apart: 21 of San Leandro's 22 licenses (95.5%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 193 of the county's 194 licenses carry the same $25,000 bond California sets by statute. 15 county licenses reach their expiration date within the next 90 days. CSLB cannot link straight to a license record, so every listing above shows its number for you to type into CSLB's license lookup. How we verify.

Does California license roofers?

Only CLEAR, unexpired licenses appear here.
How do I check a roofer's license in California?
Every listing above shows its CSLB license number.
