What is Certificate of Insurance?

Roofing Glossary · Business & Contracts

Definition

A document issued by an insurance company or broker verifying that a contractor carries active general liability and workers' compensation insurance policies. Homeowners should always request and verify a COI before work begins. A valid COI lists the insurer, policy numbers, coverage amounts, and expiration dates. Hiring an uninsured contractor creates personal liability if a worker is injured or property is damaged during the project.
