11.2 Business Insurance and Surety Bonds
Key Takeaways
- Insurance is a two-party risk transfer where the insurer expects no repayment, while a surety bond is a three-party credit guarantee under which the contractor must indemnify and reimburse the surety for every dollar it pays.
- A commercial general liability policy excludes bodily injury to the contractor's own employees, damage to the contractor's own work product, and contractual liability outside an insured contract, so it is not a warranty of workmanship.
- Products-completed operations coverage responds to damage arising after the roofing work is finished and put to its intended use, which is where most roofing water-intrusion claims land.
- Tools and equipment are not covered by a general liability policy or by most commercial property forms; a roofing contractor needs an inland marine tools and equipment floater or an installation floater for material in transit and stored on site.
- Bid, performance, and payment bonds are three distinct instruments: the bid bond guarantees the bidder will enter the contract, the performance bond guarantees completion, and the payment bond guarantees payment to subcontractors, laborers, and suppliers.
Business Insurance and Surety Bonds
Quick Answer: Insurance is a two-party transfer of risk — you pay a premium, the insurer pays a covered loss, and it does not come back to you. A surety bond is a three-party credit guarantee — the surety pays the obligee, then collects every dollar back from you under the indemnity agreement. A roofing contractor's core program is commercial general liability (with products-completed operations), commercial auto, workers' compensation, a tools and equipment floater, an installation floater or builder's risk, and an umbrella. The three project bonds are bid (you will sign the contract), performance (you will finish the work), and payment (your subs, laborers, and suppliers will be paid).
1. Insurance vs. Suretyship — The Distinction That Gets Tested
| Insurance | Surety Bond | |
|---|---|---|
| Parties | Two — insurer and insured | Three — principal (the contractor), obligee (the party protected), surety |
| Economics | The premium prices an expected loss; losses are anticipated | The premium is a fee for a credit guarantee; the surety underwrites to zero expected loss |
| Recovery from you | None — the insurer absorbs the loss | Full — you sign a general indemnity agreement and must reimburse the surety |
| Underwriting | Based on the hazard | Based on your character, capacity, and capital — essentially a credit decision |
Every CSLB bond is a surety instrument. When a surety pays a consumer claim on your $25,000 license bond, the surety will pursue you for reimbursement, and the claim goes on your record.
2. Commercial General Liability (CGL)
The CGL responds to third-party bodily injury and property damage arising out of your operations.
Coverage parts:
- Coverage A — bodily injury and property damage liability
- Coverage B — personal and advertising injury
- Coverage C — medical payments, paid without regard to fault
- Products-completed operations — damage arising after your work is finished and put to its intended use. This is where roofing water-intrusion claims land, so never let it be stripped out.
Occurrence vs. claims-made. An occurrence form covers injury or damage that happens during the policy period, whenever the claim is made — critical in roofing, where a leak may not appear for years. A claims-made form only responds if the claim is reported during the policy period or an extended reporting period. Buy occurrence.
The Exclusions That Surprise Roofers
- Bodily injury to your employees — that is workers' compensation's job, not the CGL's
- Damage to "your work" — the CGL pays for the ruined hardwood floor and the destroyed inventory below the leak; it does not pay to replace the defective roof you installed. A CGL is not a workmanship warranty.
- Faulty workmanship as such, absent resulting damage to other property
- Contractual liability you assume outside an "insured contract," which makes indemnity clauses in subcontracts worth reading before signing
- Pollution, which can reach spray foam, coatings, solvents, and fuel
- Professional liability, which matters when a roofer specifies or designs an assembly
3. The Rest of the Program
| Coverage | Why a roofing contractor needs it |
|---|---|
| Commercial auto | Trucks and trailers; include hired and non-owned auto for employees driving personal vehicles on company business |
| Tools and equipment (inland marine floater) | Neither the CGL nor a standard property form covers your own tools, compressors, generators, and lifts — on site or in the truck |
| Installation floater / builder's risk | Material in transit, stored at the site, and installed but not yet accepted |
| Umbrella / excess liability | Raises the limits above the CGL and auto; commonly required by general contractors and public owners |
| Employment practices liability (EPLI) | Wrongful termination, harassment, discrimination, and wage-and-hour defense — the exposures in Chapter 10 |
| Professional liability / contractor's E&O | Design-build and specification work, where the loss is an error in judgment rather than an accident |
| Cyber | Customer data, financial records, and funds-transfer fraud |
Reading a Certificate of Insurance
A certificate is evidence, not a policy. What actually matters:
- Named insured exactly matching the legal entity you contracted with
- Policy period covering the dates of the work
- Limits — per occurrence, general aggregate, and a separate products-completed operations aggregate
- Additional insured endorsement naming your firm, with the endorsement form number shown — not just a checkbox
- Waiver of subrogation where the subcontract requires one
- Primary and non-contributory wording where required
- Cancellation notice provisions
Collect current certificates from every subcontractor before mobilization, and diary the expiration dates.
4. Surety Bonds
The CSLB Licensing Bonds
| Bond | Authority | Amount | Protects |
|---|---|---|---|
| Contractor's License Bond | B&P § 7071.6 | $25,000 | Consumers damaged by fraud, misrepresentation, or willful code violations, and wage earners not paid lawful wages or fringe benefits |
| Bond of Qualifying Individual | B&P § 7071.9 | $25,000 | Same beneficiaries; required for every RME and for an RMO owning under 10 percent of voting stock |
| Disciplinary Bond | B&P § 7071.8 | $25,000 to $250,000 | Required for reinstatement after suspension or revocation |
| LLC Employee/Worker Bond | B&P § 7071.6.5 | $100,000 | Employees or workers damaged by an LLC's failure to pay wages, interest, or fringe benefits |
The Three Project Bonds
| Bond | Guarantees | Typical amount |
|---|---|---|
| Bid bond | That the low bidder will enter into the contract and furnish the required bonds; if it refuses, the surety pays the owner's cost to go to the next bidder | Commonly 5 to 10 percent of the bid |
| Performance bond | That the contractor will complete the work per the contract; on default the surety may finance the contractor, tender a replacement, or pay damages | Commonly 100 percent of the contract |
| Payment bond | That subcontractors, laborers, and suppliers will be paid; mandatory on California public works contracts over $25,000 under Civil Code § 9550 | Commonly 100 percent of the contract |
Why the payment bond exists. Mechanics liens cannot attach to public property. The payment bond and the public stop payment notice are the substitute remedies, which is why a roofing subcontractor on a school job protects its rights through the bond rather than through a lien.
What a Surety Underwrites
The three C's: Character (reputation, claims and litigation history, CSLB record), Capacity (backlog, crews, equipment, experience with work of this type and size), and Capital (working capital, net worth, and CPA-prepared financial statements). A single-project bond for a $200,000 roofing job is a modest hurdle; a $5,000,000 program requires reviewed or audited statements and a real balance sheet. Build the surety relationship before you need the bond — the same advice as the line of credit in Section 9.1.
A roofing contractor installs a low-slope membrane that leaks two years later, ruining $60,000 of tenant inventory and requiring $40,000 to replace the defective roof. How does a standard occurrence-form CGL with products-completed operations coverage respond?
A surety pays a $12,000 claim on a roofing contractor's $25,000 CSLB license bond. What happens next?
