Business insurance for roofers in California
Published 2026-06-11 · by Brokly
What insurance do California roofing contractors need?
Each requirement and definition below cites its statute, regulator, or public reference — full sources at the end of this section.
You're required to have
Covers your roofing crews' on-the-job injuries — and construction carve-ins start the mandate at one employee in some states.
Required from the first employee — every California employer with one or more employees must carry workers' compensation coverage.
Pays medical care and lost wages when an employee is hurt working. Roofing is treated as construction work in states with construction-industry carve-ins, which apply a lower employee threshold — Missouri's construction-employer rule names roofers by trade, and Florida reaches one-employee crews. Falls are the leading cause of work-related injuries and deaths among roofers — the crew works at height all day, which is why roofing sits among the highest-rate workers' comp classes.
Typically covers
- Medical bills for a work injury, at rates the state sets
- Part of the injured employee's lost wages
- The employer too: covered employees generally can't sue over the injury
Typically doesn’t
- Injuries outside work
- Independent contractors, in most states
- Lawsuits that get around the can't-sue trade-off — that's the employer's liability part of the same policy
California's contractor licensing law (Bus. & Prof. Code § 7125) requires active C-8 Concrete, C-20 Warm-Air Heating/Ventilating/Air-Conditioning, C-22 Asbestos Abatement, C-39 Roofing, and C-61/D-49 Tree Service contractors to carry workers' compensation insurance (or valid self-insurance certification) even if they have no employees; CSLB will not issue or renew the license without it.
Beginning January 1, 2028, every CSLB-licensed contractor — regardless of classification — must carry workers' compensation insurance even with zero employees: SB 216 (2022) originally set this universal mandate for January 1, 2026, but SB 1455 (Stats. 2024, Ch. 485) delayed it to January 1, 2028; until then, no-employee contractors outside the five mandated classifications may file a workers' comp exemption certificate with CSLB.

Required in specific situations
Liability and property-damage protection for the trucks that haul crews, shingles, and tear-off debris to job sites.
California requires owners and operators of motor vehicles — including commercial and fleet vehicles such as a contractor's van or a delivery car — to carry minimum liability insurance of $30,000 for bodily injury or death of one person, $60,000 for bodily injury or death of more than one person per accident, and $15,000 for property damage (30/60/15), per Insurance Code §11580.1b as raised by SB 1107 effective January 1, 2025.
Required if the business puts owned or leased vehicles on public roads — nearly every state requires auto-liability coverage to operate them.
Commercial auto insurance includes liability and property-damage protection for cars, trucks, and vans used for business — for a roofing contractor, the trucks that carry crews, materials, and ladders to customer job sites. The trade runs on trucks — crews, shingle pallets, and tear-off debris move to and from a different customer's roof job after job.
Typically covers
- Liability when a business vehicle injures someone or damages property
- Accidents in vehicles titled to the business, driven by employees for work
- The liability minimums states set for business vehicles
Typically doesn’t
- Your liability when employees drive their own cars for work — that's hired and non-owned auto; the employee's own car stays on their personal policy
- The freight or goods being hauled — that's cargo or inland marine coverage
- Damage to your own vehicle, unless physical damage coverage is added

A licensing financial guarantee — not insurance for the business — some states require on file before issuing the license.
California conditions the statewide contractor license that lets a business contract roofing work (CSLB C-39 Roofing classification) on filing a $25,000 Contractor's Bond with the Contractors State License Board before the license can be issued, reactivated, or renewed (Business and Professions Code § 7071.6) — the same single fixed bond required of every CSLB classification.
Required if your state's (or city's) licensing law conditions the roofing or contractor license on filing a surety bond — the license won't issue or renew without it.
A contractor license bond is a financial-guarantee instrument the contractor buys from a surety and files with the licensing authority; it protects the public, not the contractor. Where a state conditions the roofing or contractor license on one — Illinois, for example, requires a continuous bond on file for its statewide roofing license — the license will not issue or renew without it; the amounts, and which states require one, vary by licensing law. Where the licensing board demands it, the bond is a gate on the license itself — a roofing contractor in a bond state cannot legally operate without one on file.
Typically covers
- Customers or the state, if you break the licensing board's rules
- The licensing requirement itself — where a board demands a bond, no bond often means no license
Typically doesn’t
- You — the surety collects any payout back from you
- Injuries or property damage from your work — that's general liability
- Big-job performance disputes — a performance bond is its own instrument

Worth a look for this trade
Third-party injury and property damage — including water intrusion your completed roof causes after the crew has left.
Protects the business against claims of bodily injury, property damage, and personal injury. Its products/completed-operations section pays for damage that occurs away from your premises and is caused by your completed work — the defining roofer exposure, since a roof failure lets water into the customer's building long after the job closes. Oklahoma, for example, conditions its statewide roofing-contractor registration on this policy ($500,000 for residential work, $1,000,000 for commercial). A roofer's biggest exposure survives the job: a roof that leaks soaks the building below it months after the crew leaves.
Typically covers
- Injuries to customers, visitors, and other third parties
- Damage your operations cause to someone else's property
- Legal defense for covered claims
Typically doesn’t
- Your employees' injuries — that's workers' compensation
- Mistakes in professional advice or design — that's professional liability
- Redoing your own faulty workmanship itself

Inland-marine coverage for the ladders, nail guns, and compressors that live on the truck and the job site.
Inland marine insures movable business property — contractor equipment and property in transit — wherever the work is. For a roofer that means the ladders, hoists, nail guns, and compressors riding between job sites and staged on open roofs rather than at a fixed premises. A roofer's equipment lives on the truck and the open job site — inland marine is the property line built to follow it.
Typically covers
- Tools and equipment that travel — in trucks, on job sites, between locations
- Theft from a vehicle or job site, a common loss
- Rented or borrowed gear, when it's listed on the policy
Typically doesn’t
- Gradual wear and breakdown
- Tools that stay at your shop — that's commercial property
- The vehicles themselves

Errors-and-omissions coverage for roofing businesses that sell design input, consulting, or planning beyond the installation itself.
Professional liability — errors and omissions — covers losses from errors in judgment, breaches of duty, or negligent acts in the performance of services for others. For a roofing contractor that means the professional side of the trade: roof-system design input, consulting, and construction planning. It is a separate exposure from the jobsite bodily injury and property damage that general liability addresses. A roofer who advises — design input, system consulting, construction planning — is selling judgment as well as installation, and judgment errors are a professional exposure of their own.
Typically covers
- Financial harm from advice, designs, or specs that turn out wrong
- Client claims that work failed inspection or missed a professional standard
- Legal defense for those claims — often the largest cost
Typically doesn’t
- Bodily injury or property damage — that's general liability
- Intentional wrongdoing
- Work redone purely as warranty or goodwill

What does it all cost?
