Commercial Umbrella Insurance

An umbrella can add liability capacity above specified underlying policies, but it does not automatically broaden every exclusion or fill every gap.

01 · Structure

Start with the underlying schedule

Confirm exactly which general liability, auto, employer, or other policies sit underneath the umbrella and which minimum limits must be maintained.

  • Review whether the umbrella follows the underlying coverage or has its own exclusions.
  • Test limits against severe but plausible injury, vehicle, product, and premises scenarios.
  • Coordinate renewal dates and report material operational changes.
02 · Limit

More limit is not the same as different coverage

Professional mistakes, cyber events, employment disputes, and other exposures may need their own policies or endorsements.
