Completed Operations Insurance for Commercial Roofing Contractors
Completed operations coverage is the part of your general liability policy that responds to bodily injury or property damage claims arising from work you've already finished. For commercial roofers, this is critical — a membrane failure, flashing defect, or improper drainage detail may not manifest until months or years after project completion. Without adequate completed operations limits, you're exposed to every past project indefinitely.
What It Covers
Completed operations covers third-party bodily injury and property damage that results from your finished work. If a roof you installed two years ago develops a seam failure that causes $200,000 in water damage to the building's interior, completed operations responds. It covers the resulting damage to the building owner's property and any injury claims — though not the cost of redoing your own defective work. Defense costs are included.
What It Does Not Cover
Completed operations does not cover the cost of repairing or replacing your own defective work — only the resulting damage to other property. It does not cover claims arising from intentional shortcuts, contractual warranty obligations for material performance, or damage discovered during a project still in progress (that falls under premises/operations coverage).
Real Claim Examples
Eighteen months after completing a TPO roof on a data center, a seam weld fails during heavy rain. Water penetrates the server room, destroying $400,000 in equipment — completed operations covers the interior damage (not the roof repair itself). A modified bitumen roof installed on a restaurant separates at a penetration point, allowing water to damage the commercial kitchen below and forcing a two-week closure with $85,000 in losses. A standing seam metal roof you installed develops a galvanic corrosion leak at dissimilar-metal contact points, causing $60,000 in ceiling and insulation damage to the occupied floors below.
How Much It Costs
Completed operations is typically included in your GL policy and rated based on your annual revenue. Commercial roofers pay a completed operations rate of $15 to $40 per $1,000 of revenue depending on the systems they install and their claims history. A $3M revenue contractor might pay $45,000 to $120,000 in total GL premium with completed operations included.
