What a Commercial Umbrella Covers and What It Does Not

A commercial umbrella covers bodily injury, property damage, and personal and advertising injury claims that exceed your general liability, commercial auto, and employers liability limits, usually with defense costs on top. It can also cover some claims those policies exclude, after a self-insured retention. It typically excludes professional liability, cyber, employment practices, pollution, D&O, and workers comp benefits.

The short version

Above the underlying policies: the umbrella pays once general liability, auto, or employers liability limits are used up.
Sometimes broader: some umbrellas cover claims the underlying policies exclude, after a self-insured retention, and drop down if an underlying aggregate is exhausted.
Defense is often in addition to limits, but not always; check the form.
What it leaves out: professional services, cyber, employment practices, pollution, D&O, and the workers comp benefits themselves.
Washington detail: employee injury suits are covered above stop-gap, not above L&I. See the Washington stop-gap gap.

What a commercial umbrella usually covers

Coverage	Example
Bodily injury above general liability	A customer is seriously injured in a fall at your store
Property damage above general liability	Your crew causes a fire that destroys a client's building
Products and completed operations	A product you sold or a job you finished causes injury years later
Auto liability above commercial auto	A company truck causes a multi-vehicle accident
Hired and non-owned auto	An employee crashes their own car on a work errand, if scheduled underneath
Employers liability above stop-gap or Part Two	An employee injury suit outside workers comp immunity
Personal and advertising injury	Defamation, false arrest, or wrongful eviction claims
Defense costs	Often paid in addition to the limit
Some claims the underlying excludes	Coverage the umbrella provides on its own terms, after a self-insured retention

What it usually does not cover

Exclusion	Where coverage comes from instead
Professional services	Professional liability or E&O, with its own excess
Cyber and data breaches	Cyber insurance
Employment practices	EPLI; see the EPLI guide
Directors and officers claims	D&O
Pollution, beyond limited exceptions	Pollution liability
Workers comp benefits	L&I in Washington; workers comp in Idaho
Your own property	Property insurance
Expected or intended injury	Not insurable
Aircraft and some watercraft	Aviation or marine policies

The terms that change what you get

Term	Why it matters
Follow form vs standalone	A follow-form umbrella mirrors the underlying; a standalone form has its own coverage and exclusions
Self-insured retention	The amount you pay on claims the umbrella covers but the underlying does not
Drop down	Whether the umbrella steps in when an underlying aggregate is exhausted
Defense inside or outside limits	Defense outside the limit preserves more for settlements
Schedule of underlying insurance	The policies and limits the umbrella assumes are in place; see underlying requirements
Named insureds	Every entity, including LLCs, should be listed
Additional insureds	Contract parties covered under your general liability are often covered by the umbrella only if the policy says so

Common questions

Does a commercial umbrella cover auto accidents?

Yes, above your commercial auto limit, if commercial auto is scheduled as underlying insurance. That includes hired and non-owned auto if those coverages are in the underlying auto policy.

Does a commercial umbrella cover employee injuries?

Not workers comp benefits, which come from L&I in Washington or a workers comp policy in Idaho. It covers employee injury lawsuits above employers liability, which in Washington means stop-gap.

Does a commercial umbrella cover professional liability?

Usually not. Professional services are commonly excluded. Higher professional liability limits come from an excess policy written over the professional liability policy.

Does a commercial umbrella cover additional insureds?

Often, but only if the umbrella extends coverage to parties who are additional insureds on the underlying policy. Contracts that require umbrella coverage for the other party need this checked.

What is a self-insured retention on an umbrella?

The amount you pay before the umbrella responds to a claim it covers that the underlying policies do not. It does not apply to claims the underlying policies cover, where the underlying limit serves as the retention.
