What Los Angeles asks of a roofing business, and where your website comes in.
Checked 2026-10-05 at each source. Not legal advice: rules change, so check with the board before you rely on one.
State · California Contractors State License Board (CSLB)
Roofing is the C-39 classification, and the license number goes on your ads.
“Every person licensed pursuant to this chapter shall include his license number in: (a) all construction contracts; (b) subcontracts and calls for bid; and (c) all forms of advertising”
What it covers
“A roofing contractor installs products and repairs surfaces that seal, waterproof and weatherproof structures.”
California · every trade
CSLB counts any website or post that asks for work on the internet as advertising.
CSLB, Advertising Guidelines for ContractorsCalifornia · every trade
Advertise only the work your classification covers, and never say you are bonded.
CSLB, Advertising Guidelines for ContractorsOn your website
Put the number in the footer of every page and beside every quote form, under the business name it is issued to. Read every page as an ad: that is the safe reading of these rules.
Service area
The Los Angeles-Long Beach-Anaheim, CA metro: 2 counties.
California licenses contractors state-wide through the CSLB, so these rules hold across both counties of the metro.
