The first thing an ember touches is your work: going out on your own with a C-39

In most of the country a roof is a water problem. In California it is a fire problem too, and in a large part of the state the fire half is written into the plans. An ember lands on your assembly, finds the vent, the eave, the valley or the tear-off you left in the wrong place, and everything under it is gone.

That is not a warning, it is a market. Whole neighborhoods are being rebuilt, the rebuild has a specified envelope, and the contractor who understands the specification is not competing on price with the crew handing out flyers. This page is what it takes to be the name on that contract with a C-39, and it leads with Chapter 7A because nothing else moves as much money on this trade.

Chapter 7A, 100 feet, and the five feet closest to the house

Inside a fire hazard severity zone, Chapter 7A of the building code governs the exterior envelope. Defensible space runs 100 feet from the structure, with an ember-resistant zone within 5 feet of it. For a roofer that turns into three working facts.

The assembly is specified, not chosen on site. The covering, the underlayment and the way the edge is closed were selected together to satisfy that chapter, so a substitution made because the yard was short will be judged at inspection as one.

The openings are where the job is won. Embers do not attack a field of tile, they find the way in: vents, eaves, the roof to wall intersection, the valley, the ridge. That detailing is the part of the bid a homeowner cannot evaluate and a plan checker can.

The 5 foot zone is on the ground, and your trade fills it. Tear-off, felt, pallets and a rolling dumpster all land in the strip the code cares about most, in front of a neighbor who has already lost one house.

The rules are local as well as statewide. California builds to Title 24 rather than the I-Codes, the edition in force is fixed by the permit application date, and local amendments require express findings filed with the Commission, so the detail the next jurisdiction accepted is not automatically the one this plan checker passes. Building in a California wildfire zone is the envelope page.

Rebuild work is contract work, and the cancellation clock is longer

Reroofing is mostly signed directly with a homeowner, which puts it under the home improvement contract rules in the BPC s.7159 family. Written contract above $500. Down payment capped at the lesser of $1,000 or 10 percent. Payments may not run ahead of the value delivered. Prescribed headings and type sizes are mandatory. Change orders signed before the extra work starts.

Then the clause that matters in a burn area: the right to cancel is three business days, with longer periods for some buyers and after a declared disaster. Rebuild work is where that longer period applies, and a template bought out of state does not carry it, which turns a signed job into one that walks in week two.

Put numbers on a real reroof. Tear-off and full assembly replacement, contract price $38,000.

Two point six percent, on a trade where the tear-off, the disposal and most of the material hit in the first 48 hours. The answer is a progress schedule in stages the customer can see and an inspector can date: tear-off and deck, dry-in, assembly complete, flashings and penetrations, final, each billed as it is delivered. Written at the kitchen table, that schedule is the difference between a roofing company and a roofing crew. The home improvement contract rules and change orders that get paid come before you print a contract pack.

Your money as the direct contractor, on real dates

Signing with the owner makes you the direct contractor, so the clocks are yours rather than a general's. Take a reroof completed on 10 July 2026.

A Notice of Completion must be recorded within 15 days of completion, and when one goes on record your window collapses by a month without anyone telling you, which is why the completion date belongs in the job file the day you final. One more rule ends arguments early: the Notice of Mechanics Lien has to be served with the claim, and failure to serve makes the lien unenforceable as a matter of law under Civ. Code s.8416. The California lien deadline calculator produces the dates and California mechanics lien deadlines is the full sequence.

Seven and a half feet, and a July that starts at six in the morning

Fall protection in construction starts above 7.5 feet, and no trade in California lives at that number the way roofing does. Shade is required once the outdoor temperature exceeds 80 degrees, high-heat procedures begin at 95 degrees with construction named, and drinking water runs at one quart per employee per hour. None of that is free, which is why it belongs in the labor rate rather than in a resolution to be careful. A roofer who prices the shade, the water, the early start and the fall protection into a July job is bidding the real cost while the competition bids a number that only holds if nothing goes wrong. Cal/OSHA and the IIPP sets up the rest of the file once.

What the C-39 covers, and the classes at the edges

The classifications sit in the 16 CCR 832 family and work outside the class you hold is not permitted. The C-39 installs and repairs roofing systems: the covering, the underlayment, the insulation in the assembly, the flashings that close it and the waterproofing with it.

Solar is the interesting edge. A reroof and an array are the same customer on the same roof, the penetrations are yours either way, and who goes first decides whose warranty is at risk. A C-39 who also holds C-46 solar owns that conversation instead of coordinating it. C-43 sheet metal is the other natural second, since flashings and metal roofing sit on the boundary.

Where the customer wants the roof, the siding and the windows under one contract, a B taking a prime contract needs at least two unrelated building trades or crafts under BPC s.7057(a). Rebuild work asks for that shape, which is why some roofers add a B once the jobs they turn down are bigger than the jobs they take.

Four years, the exam, and the money to open

Four years of journey-level experience within the last ten (16 CCR 825), with education creditable for up to three of them. Journey-level counts as journeyman, foreman, supervising employee or contractor, which for a roofer is the years you laid out the job, called the assembly and the flashing details, ran the crew and handed over a roof that passed. What CSLB counts as experience has the certifier list.

Two exams, Law and Business at about 115 questions and the trade exam at about 100, multiple choice and closed book at a PSI test center, calibrated per version rather than against a fixed percentage. Working roofers pass the installation content and get caught by estimating arithmetic, plan reading, and assembly and fire classification detail in written form. The two exams is the study map.

Money to open: $450 for the original application, $200 to issue as a sole owner or $350 otherwise, biennial renewal at $450 or $700 with no continuing education, the $25,000 license bond under BPC s.7071.6, plus a $100,000 employee and worker bond on the LLC route under BPC s.7071.6.5. Workers compensation goes in before anyone else is on the roof, because the license is suspended by operation of law the day cover lapses. The application sequence, the bond and the qualifier, workers comp and choosing the entity run in that order.

Where the roofing work is

Reroofing is the most permit-visible work in the state. Building permits published by Los Angeles, San Francisco, San Diego and Sacramento name the property and often the contractor, and rebuild communities concentrate that signal into a few streets at a time. CEQAnet filings surface institutional and multifamily projects at environmental review, months before a general assembles a bid list.

Public work is the steady lane, because school and municipal reroofs are planned, funded and repeated. Prevailing wages apply over $1,000, DIR registration is required to bid and renews July 1, certified payroll is filed electronically at least monthly, and school work goes to DSA rather than the city. Where work is starting in California covers the sources and what to charge builds the rate.

Bid the assembly and the detail, not the square

Take the last fire zone roof you worked on for somebody else and write down the hours that went into the vents, the eave, the valley and the roof to wall intersection. Compare that to what it was bid at per square. That gap is the difference between the two companies you could start.

On AEC Stack there is no monthly subscription. The platform fee is 2.5 percent of each invoice processed through the platform, so the quoting and the invoicing earn their keep on jobs that actually pay.

Open a working business file, put your next reroof in it with the stage billing and the completion date, and get the lien window on the calendar before you need it.
