Completed Operations Insurance for Commercial Roofing Contractors

CG 00 01 Products-Completed Operations Aggregate

Within the standard GL occurrence form, the products-completed operations aggregate is a separate limit that applies to claims arising from work you have completed and handed over to the customer. For roofing contractors, this is where the majority of high-value claims originate — roof leaks, flashing failures, membrane delamination, and ponding issues that surface months or years after project completion. The standard $2M aggregate can be consumed by a single large water intrusion claim, so roofers should consider increasing this limit or purchasing a separate completed operations policy.

CG 20 37 — Additional Insured — Completed Operations

This endorsement extends your completed operations coverage to GCs and building owners named as additional insureds. It is increasingly required on commercial roofing contracts alongside the ongoing operations additional insured endorsement (CG 20 10). Without CG 20 37, the GC has no coverage under your policy for completed operations claims — precisely when they are most likely to be named in a lawsuit alleging a roof defect discovered after project completion.

Extended Completed Operations Reporting Period

Some policies offer an optional extended reporting period that allows claims arising from completed roofing work to be reported beyond the standard policy period. This is valuable when transitioning between insurers, as it prevents a gap in completed operations coverage. For roofers, statutes of repose for construction defects range from 6-12 years depending on the state, creating long-tail exposure that must be continuously covered.

Per-Project Completed Operations Aggregate

This endorsement provides a separate completed operations aggregate for each project rather than sharing a single aggregate across all completed work. For active commercial roofers completing dozens of projects annually, a per-project aggregate ensures that a claim on one job does not reduce available coverage for claims on other projects. This endorsement typically costs 5-10% additional premium but dramatically reduces aggregate erosion risk.

Acuity

Acuity provides robust completed operations coverage as part of their standard GL policy for roofing contractors. Their per-project aggregate is available at competitive rates, and they do not impose a sunset clause that limits completed operations coverage to a specific number of years after project completion. Acuity's completed operations coverage includes property damage from faulty workmanship to non-defective building components — a coverage grant some competitors restrict. Their claims handling for water intrusion claims is efficient, typically resolving completed operations claims within 90 days.

FCCI

FCCI's completed operations coverage for roofers includes a strong subcontractor exception that preserves coverage when a sub's defective work causes damage to the contractor's completed project. This is crucial for roofing contractors who subcontract sheet metal, gutter, or skylight installation. FCCI's completed operations aggregate can be increased to $4M for a modest additional premium. They require detailed quality control documentation and project completion checklists as part of their underwriting, but reward compliant contractors with 5-8% premium credits.

Hartford

Hartford's completed operations coverage for roofing contractors is comprehensive but comes at a premium — expect to pay 15-20% more than Acuity or FCCI for comparable limits. Hartford's advantage is their broad definition of "your work" in the completed operations context, which includes materials and components supplied by others but installed by the roofer. Their completed operations claims team includes construction defect specialists who manage complex multi-party litigation efficiently.

Kinsale

Kinsale writes completed operations coverage on an E&S basis for roofing contractors with adverse completed operations loss histories. Their policies may carry specific exclusions for certain roof types — such as spray polyurethane foam (SPF) or green roofs — that have historically generated frequent completed operations claims. Kinsale's pricing for completed operations is 30-50% above standard market, but they provide essential coverage for contractors who have been non-renewed by admitted carriers after significant completed operations claims.

$740,000 — Membrane Failure on Hospital, Tampa, FL

A roofing contractor installed a 120,000-square-foot TPO membrane roof system on a hospital expansion. Fourteen months after completion, widespread seam failures caused water intrusion into surgical suites and patient rooms. The hospital incurred $460,000 in interior repair costs, $180,000 in equipment replacement, and $100,000 in patient relocation expenses. The completed operations coverage paid the full $740,000 claim. Investigation revealed the contractor's crew had used incorrect welding temperatures during installation, causing weak seam bonds. The contractor's completed operations aggregate was nearly exhausted by this single claim.

$195,000 — Flashing Failure at Retail Center, Columbus, OH

Eight months after completing a commercial re-roofing project on a strip retail center, multiple tenants reported water leaking at the parapet walls. Investigation revealed that counter-flashing was improperly sealed, allowing wind-driven rain to penetrate behind the flashing and into the building envelope. The completed operations claim totaled $195,000 covering interior tenant improvements, damaged inventory, and roof repair costs. Three tenants filed separate claims, each processed under the contractor's completed operations coverage. The contractor implemented a flashing inspection protocol for all future projects.

$425,000 — Ponding Water Structural Damage, Minneapolis, MN

A roofing contractor completed a flat roof replacement on a commercial warehouse and certified proper drainage. Two years later, chronic ponding water in a low area caused structural decking to deteriorate and eventually collapse, damaging stored inventory below. The building owner's structural engineer determined that the roofing contractor failed to correct existing drainage deficiencies during the re-roofing project. The completed operations claim reached $425,000, including $280,000 in structural repairs, $95,000 in inventory damage, and $50,000 in business interruption. The claim took 18 months to resolve due to the structural engineering dispute.
