How can I find out if a roofing contractor is licensed in California?

A licence is a filter rather than a guarantee. It lapses, companies change hands, and a certificate of insurance issued this month is a separate question from the licence. Roofing is the C-39 classification with the Contractors State License Board, and any company can be checked on the board's own register in under a minute — number, status, expiry, bond and workers' compensation. Every licensed contractor must put the licence number in all advertising and in contracts, subcontracts and bids, so an advertisement without one is itself a signal. The minor-work exemption that lets very small jobs go unlicensed rose to $1,000 in 2025 and does not apply to permitted work in any case — and a re-roof requires a permit, so a re-roof requires a licensed contractor whatever it costs.

What the licence is and what it covers

The register is public, free, and current — which is more than can be said for a number printed on a van. The deposit is capped by statute. A home improvement contractor may not take a down payment of more than $1,000 or ten per cent of the contract, whichever is less, unless they have a blanket performance and payment bond on file with the board. Exceeding it is a misdemeanour, and in a declared disaster area the court is required to impose the maximum fine — which tells you how commonly it is attempted after a storm. The unlicensed-work threshold is no longer $500. AB 2622 raised the minor-work exemption to $1,000 from 1 January 2025 — and it does not apply to permitted work in any case, so a re-roof always requires a licensed contractor whatever it costs. The dollar figure is a distraction; the permit is the thing that settles it.

The deposit cap

This is a number worth knowing before a contract is in front of you rather than after. Every licensed contractor is required to put the licence number in all advertising, and in contracts, subcontracts and bids. An advertisement without one is itself a signal. The board's own register will confirm a number in under a minute, and it is worth the minute. A home improvement contract can normally be cancelled within three business days, and within five if the buyer is a senior citizen. Where the contract is to repair or restore residential damage from a disaster or a declared state of emergency, that window is seven business days. It exists precisely because of what happens in a neighbourhood after a storm. Nothing has to be signed on a doorstep, and if something was, the clock above is the reason to read it again tonight rather than tomorrow. Roofing is the C-39 classification with the Contractors State License Board. The minor-work exemption that lets very small jobs be done unlicensed rose to $1,000 at the start of 2025, but it does not apply to work that requires a permit — and a re-roof requires a permit. The practical rule is therefore simpler than the statute: a re-roof needs a licensed contractor, whatever it costs.

What to ask a roofer in Aliso Viejo

Three quotes for the same roof will look similar and mean different things. These are the questions that make the difference visible. Building permits for a re-roof in Aliso Viejo are issued by City of Aliso Viejo Building & Safety Department. The classification is decided address by address rather than city by city, so two houses on one street can fall on different sides of a line. Since the zone is what pulls in the Class A requirement and the ember-resistant details, which zone your address is in is the first question rather than the last. Not all of the tile survives being lifted. A few per cent breakage is normal, matching a discontinued profile is the hard part, and a quote that does not say what happens to unusable tile has a hole in it. Roofing is licence classification C-39 in California, and any company can be checked on the Contractors State License Board lookup in about thirty seconds — licence number, status, expiry, bond and workers' compensation all on one screen. Ask for the answers in writing. Not because anybody is lying, but because a written answer is one you can compare against another written answer.

• Who carries the workmanship warranty, for how long, and what happens to it if the company is sold?
• What exactly are the fasteners and the flashing metal, by name, and why those?
• What is the rate for replacing rotten decking, per sheet, agreed before anybody starts?
• What is the payment schedule, and what is the deposit as a percentage?
• How many layers are you expecting to remove, and what happens to the price if there turn out to be more?
