Completed operations coverage is not an optional add-on for commercial roofing contractors—it is a fundamental requirement for doing business. Yet many contractors underestimate both its cost and its importance, treating it as a line item to minimize rather than a critical protection against the claims most likely to threaten their business. Here is what completed operations actually costs, why you cannot avoid it in commercial work, and what happens when it triggers.
How Completed Operations Is Priced
Completed operations is part of your Commercial General Liability (CGL) policy—specifically Coverage A, which responds to bodily injury and property damage claims. It is not a separate policy but a component of GL with its own rating methodology and aggregate limit.
The pricing mechanics:
Rating basis: Completed operations is rated on the same revenue basis as your premises/operations GL coverage, but at a separate rate. For commercial roofers in Texas, the completed operations rate typically runs $3–$8 per $1,000 of revenue, layered on top of the premises/operations rate of $5–$12 per $1,000. Combined, your total GL rate includes both components.
What this means in dollars:
- $3M revenue contractor: Completed operations component = $9,000–$24,000 annually
- $5M revenue contractor: Completed operations component = $15,000–$40,000 annually
- $10M revenue contractor: Completed operations component = $30,000–$80,000 annually
The completed operations portion typically represents 35–45% of your total GL premium. When you see a GL quote of $60,000, roughly $21,000–$27,000 of that is the completed operations component.
Aggregate limit: Most CGL policies provide a separate products-completed operations aggregate, typically equal to your general aggregate (e.g., $2M). This means you have $2M available specifically for completed operations claims, independent of your general aggregate for premises/operations claims. This separation is important—a large completed operations claim does not erode your coverage for active jobsite incidents.
Experience rating impact: Completed operations claims in your loss history increase future pricing more aggressively than premises/operations claims. A carrier views a completed ops claim as evidence of systemic quality issues that will repeat, whereas a premises claim might be a one-time incident. A single $150K completed operations claim can increase your GL rate by 15–25% at renewal.
Why Commercial Contracts Require It
General contractors, property owners, and lenders universally require roofing subcontractors to carry completed operations coverage—and to maintain it for specified periods after project completion. This is not optional or negotiable on commercial projects.
GC requirements: Standard subcontract agreements require you to maintain completed operations coverage for 2–5 years after substantial completion. The GC needs this because they face claims from building owners for roof failures that occur after the project is finished. Without your completed operations coverage responding, the GC's own policy bears the loss—or worse, the GC faces an uninsured claim.
Additional insured endorsements: The CG 20 10 (ongoing operations) and CG 20 37 (completed operations) endorsements extend your GL coverage to protect the GC and owner for claims arising from your work. The CG 20 37 specifically extends completed operations protection to additional insureds. Without this endorsement, your additional insured coverage evaporates when the project finishes—exactly when completed operations claims arise.
Lender requirements: Commercial mortgage lenders require evidence that the roofing contractor carried completed operations coverage as a condition of construction loan disbursement and ongoing compliance. If a roof fails and the contractor had no completed operations coverage, the lender's collateral is impaired without recourse.
Owner direct contracts: Even when you contract directly with a building owner (no GC), sophisticated owners require completed operations with 3–5 year maintenance periods. This is standard in commercial real estate because roof failures are among the most expensive building envelope claims.
The Claims That Trigger Completed Operations
Completed operations coverage responds to bodily injury or property damage claims that arise after your roofing work is finished and turned over to the owner. In roofing, these claims fall into predictable categories:
Water intrusion and leaks: The most common completed operations claim for roofers. A roof you installed 18 months ago develops a leak at a membrane seam, causing $200K in interior water damage to a tenant's inventory. Your completed operations coverage responds to the property damage claim from the tenant and/or building owner.
Structural damage from installation errors: Improper fastener patterns that allow wind uplift, inadequate drainage design that causes ponding and structural overload, or flashing failures that allow water into the building envelope. These claims often develop 2–4 years after installation when cumulative damage becomes apparent.
Bodily injury from completed work: A maintenance worker steps on a skylight that you improperly secured during a re-roofing project. A pedestrian is injured when facade materials detach due to improper counterflashing installation. These bodily injury claims arising from your completed work trigger the completed operations coverage.
Consequential damages: Business interruption, tenant relocation costs, and lost rent caused by roof failures. While your policy covers the property damage, consequential damages can escalate a $50K leak repair into a $500K claim when a medical office must relocate for 3 months during remediation.
Sunset Provisions and Extended Reporting
Completed operations coverage in a standard occurrence-form CGL policy covers claims arising from work completed during the policy period, regardless of when the claim is filed. However, several practical limitations affect long-term protection:
Policy maintenance requirement: Your completed operations coverage only responds if you maintain continuous CGL coverage. If you cancel your policy or let it lapse, you lose coverage for all prior completed work—even work done years earlier. This is why contracts require you to maintain coverage for specified periods after completion.
Carrier changes: When you switch carriers, your new carrier picks up completed operations exposure for work done during their policy period going forward. Work completed under prior carriers remains covered by those prior policies (assuming occurrence form). This creates a patchwork of coverage across multiple carriers over time.
Extended reporting / tail coverage: If you close your business or retire, you need an extended reporting period (ERP or "tail") to maintain coverage for completed operations claims that arise after you stop carrying active GL. Tail coverage typically costs 100–200% of your final year's GL premium for a 3–5 year extension. For a contractor with $60K in annual GL, that means $60K–$120K for extended protection.
Statute of repose: Texas has a 10-year statute of repose for construction defect claims, meaning claims must be filed within 10 years of substantial completion. This creates the outer boundary of your completed operations exposure—but 10 years is a long time to maintain coverage.
Completed operations is the cost of doing commercial roofing work. It is not a premium to minimize—it is a protection that keeps your business solvent when a roof you installed three years ago causes a $400K water damage claim. Budget it at 35–45% of your total GL cost, maintain it continuously for the duration of your contractual obligations, and ensure your additional insured endorsements include the CG 20 37 for completed operations protection. The alternative—being uninsured for post-completion claims—is a business-ending risk that no margin on a commercial job can justify.
