Permits and roofing rules in Lakewood

California rules that apply here too

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

Licensing, deposits and what has to be on the paperwork

Roofing sits under the C-39 classification at the Contractors State License Board. The small-job exemption that permits unlicensed work rose to $1,000 in January 2025, but it does not extend to work needing a permit, and a re-roof needs one. So the rule that matters is the simple one: a re-roof requires a licensed contractor, at any price.

Deposits are capped by statute at $1,000 or ten per cent of the contract, whichever is smaller, unless the contractor carries a blanket performance and payment bond with the board. Going over it is a misdemeanour, and in a declared disaster area the court must impose the maximum fine — which says something about how often it is tried after a storm.

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.

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.

Class A, the highest classification, is required where the property sits inside a fire hazard severity zone or a wildland-urban interface area, and many cities require it more widely by local ordinance. In practice, across most of south Orange County, Class A is the answer — but it comes from the fire zoning and the local ordinance rather than from a blanket statewide rule, so it is worth confirming for your address rather than assuming either way.

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 may not be laid over the old one where there are already two applications of any type on the roof, where the existing roof or covering is water-soaked or has deteriorated enough that it is no longer a sound base, or where the existing covering is slate, clay, cement or asbestos-cement tile. In those cases the roof comes off 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.
