The local rules on a Montclair roof

The statewide layer

The city rules above sit on top of these. Where the two differ, the stricter one governs.

The deductible, and the California version of the warning

Unlike Texas or Florida, California has no roofing-specific statute banning a contractor from covering your deductible. That is not permission — the illegality is in the mechanism. Billing the insurer the full amount while collecting less than that from you puts a false statement of material fact into the claim, and knowingly presenting a false or fraudulent insurance claim is a felony under Penal Code section 550, with prison exposure and fines up to $50,000 or twice the fraud.

The homeowner who agreed to the arrangement is a party to it. This is worth being blunt about because the offer is made constantly after storms and is almost always framed as a favour.

The deadlines California puts on your insurer, and on you

California puts enforceable clocks on an insurer under the Fair Claims Settlement Practices Regulations: fifteen calendar days to acknowledge a claim, supply the forms and instructions and begin any necessary investigation; fifteen calendar days to respond fully to what you send; forty calendar days from proof of claim to accept or deny; thirty calendar days from acceptance to pay. Until it decides, it owes you a written status update every thirty days.

On the other side, if the policy pays replacement cost, state law forbids the insurer from allowing you less than twelve months from the first actual cash value payment to collect the rest — and not less than thirty-six months where the loss relates to a declared state of emergency, with further extensions available for good cause and for delays outside your control such as permits or contractor availability.

The hard outer limit is the one to know: suit on the policy has to be brought within twelve months of the inception of the loss, extended to twenty-four months for a loss related to a state of emergency. Whatever else is happening, that limit does not care about how the negotiation is going, which is why a claim heading nowhere is a reason to take advice early.

Tear-off waste and where it goes

CALGreen’s 65 per cent diversion requirement for construction and demolition waste attaches to additions and alterations that increase a building’s conditioned area, volume or size. A straight re-roof does none of those, so the state mandate generally does not reach it.

Local ordinances often do, and the state code explicitly allows a city to be stricter. Several cities capture roofing work through their own construction and demolition rules by permit valuation, which can mean a deposit and a diversion report on an ordinary house. It is a question for your city, and it is worth asking before the skip arrives rather than after.

Fire classification: what is actually required, and where

The statewide floor is a Class C fire-retardant roof covering. That applies to a new roof, to any repair or replacement, and to any existing building where more than half the roof area is replaced within a year — which is every ordinary re-roof.

The highest classification, Class A, is pulled in by fire hazard severity zoning or wildland-urban interface designation, and by local ordinances that reach further. Over most of south Orange County the answer ends up being Class A — but it gets there through the zoning and the city, not through a blanket state rule, so it is a question to settle for your address.

One citation to watch for: since 1 January 2026 the wildfire provisions are their own volume, the California Wildland-Urban Interface Code at Title 24 Part 7. It absorbed what used to be building code Chapter 7A and residential code section R337. Anyone still quoting Chapter 7A is quoting a superseded document.

What a wildfire-zone roof actually has to include

Inside a mapped fire hazard zone the requirements go well beyond what the roof is covered with, and the extra details are exactly where a cheap job differs from a compliant one. It is embers rather than a flame front that destroy most houses in a wildfire, and every requirement below closes a gap an ember could use.

• A roof assembly meeting Class A when tested to ASTM E108 or UL 790
• On profiled tile, bird stops at the eaves and hip and ridge caps mudded in, so there is no open end for embers to enter
• Valley flashing of at least 0.019 inch (26 gauge) corrosion-resistant metal, over a mineral-surfaced cap sheet at least 36 inches wide
• Noncombustible gutters and downspouts, with an approved means of stopping leaves and debris collecting in them
• Vent screening of noncombustible corrosion-resistant mesh, no finer than 1/16 inch and no coarser than 1/8 inch

How many layers can stay on

A new covering cannot go over the old one where two applications are already up there, where what is there is water-soaked or degraded past being a sound base, or where the existing covering is slate, clay, cement or asbestos-cement tile. Any of those means a strip to the deck.

Two layers is therefore the practical ceiling, and on an older house nobody knows how many are up there until somebody looks. That is the single most common reason a re-roof price changes after the work starts, and it is a fair reason to ask for the quote to state what happens if a third layer appears.

Licensing, deposits and what has to be on the paperwork

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.

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.

Licence numbers are required in all advertising and on contracts, subcontracts and bids. An advert without one is itself information. The board’s register settles it in under a minute and the minute is worth spending.
