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, 21 of them registered in Livermore. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Livermore license has been held 17 years, and the longest-standing one dates to 1979. 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: 19 of Livermore's 21 licenses (90.5%) 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.
Roofers in Livermore: common questions
How many licensed roofers are there in Livermore?

Does California license roofers?
Yes.

Only CLEAR, unexpired licenses appear here.
How do I check a roofer's license in California?
Every listing above shows its CSLB license number. CSLB cannot link straight to a record, so open its license lookup and type the number in: it shows status, expiration, the contractor bond and workers' compensation cover, which California requires of C-39 licensees and 19 of Livermore's 21 currently carry. 15 Alameda County licenses expire within 90 days.
