Understanding the Limits of General Liability Insurance in Commercial Roofing
The Distinction Between Coverage and Accountability
For commercial property managers, receiving a Certificate of Insurance (COI) is a standard part of the procurement process. However, a common misconception is that a standard General Liability (GL) policy functions as a performance guarantee or a comprehensive repair fund for installation errors.
In reality, GL insurance is designed to cover third-party bodily injury or property damage caused by the contractor's operations. It is not a substitute for a workmanship warranty or a bond.
Common Limitations in Commercial Policies
When verifying a contractor’s insurance, decision-makers should be aware of several critical nuances:
- The 'Your Work' Exclusion: Most standard GL policies contain exclusions that prevent the insured from claiming the cost to repair or replace their own faulty workmanship. If a roof is installed incorrectly and leaks, the insurance may pay for the damaged drywall inside the building, but it will often not pay to fix the roof itself.
- Open Roof Exclusions: Some lower-tier commercial policies include endorsements that exclude coverage for rain damage if the roof is left 'open' during the construction process.
- Completed Operations: This specific aspect of the policy is what covers damages occurring after the project is finished. If a contractor allows their policy to lapse after the project, or if the policy lacks 'discontinued operations' coverage, the asset manager may have no recourse for issues appearing in year two or three.
Verification Beyond the COI
A COI is a summary document, not the policy itself. For high-value commercial assets, it is prudent to request the 'Schedule of Exclusions' from the contractor’s insurance broker. This ensures that the specific risks associated with commercial roofing—such as hot-applied systems or structural weight considerations—are not explicitly barred from coverage.
Key Takeaways
- Standard general liability insurance often excludes coverage for the cost of repairing the roof itself.
- A Certificate of Insurance (COI) confirms active coverage but does not detail policy exclusions.
- Completed operations coverage is necessary to address claims that arise after the contractor leaves the site.
- Verification must include checking for 'open roof' or 'water intrusion' exclusions in the policy headers.
