Snow Removal Contractor Insurance: What a COI Alone Won't Cover

A property manager asks a snow removal contractor for proof of insurance. The contractor emails over a certificate of insurance (COI) the same afternoon. Box checked, right? Not quite. A COI is a summary document your insurance agent generates on request  it is not proof that you are actually covered if that contractor's crew causes a slip-and-fall on your property. According to World Insurance Associates, an increasing number of carriers will not extend real protection to a property owner unless the contract itself requires it in writing. The certificate alone does not create that protection.

This matters more in snow and ice management than almost any other property service. Winter conditions create genuine life-safety risk, and when someone is hurt, the property owner and the contractor are usually named in the same claim together. What actually determines who is protected, and how much, comes down to a handful of policy endorsements most property managers have never been shown and most one-truck operators have never been asked for.

Why a Certificate of Insurance Isn't the Same as Being Protected

A certificate of insurance is a snapshot: it lists the contractor's carrier, policy numbers, and coverage limits as of the date it was issued. It is not a contract, and in most states it carries a disclaimer stating it confers no rights on the certificate holder. If the contractor's policy lapses the week after the certificate was issued, the certificate does not know that, and neither do you.

What actually protects a property owner is being added to the contractor's policy as an additional insured , by endorsement, with the right wording specified in the signed contract. Per World Insurance Associates, this is no longer optional in a well-run contract: "a certificate of insurance is no longer sufficient, and an increased number of insurance carriers will not provide additional insurance status unless it is required as part of the written contract." If the requirement isn't in the contract, there's a real chance the endorsement was never issued at all.

What "Additional Insured" Actually Buys You

Being named as an additional insured on a contractor's general liability policy means that if a claim is filed against both the property owner and the snow removal contractor for the same incident, the contractor's policy defends and pays on behalf of both parties not just the contractor. That's the theory. In practice, per guidance published by the Snow & Ice Management Association (SIMA), there's an important catch: additional insured status does not create new coverage limits. It's a shared limit. If the contractor's policy has a single liability limit and both you and the contractor are drawing against it for the same claim, that ceiling doesn't move just because your name was added to the policy.

That's one reason a documentation-heavy contractor is worth more than a low-bid one. General liability alone isn't automatically a snow-specific policy, and the limits, exclusions, and endorsements attached to it are exactly what determines whether "insured" means anything when a claim actually lands.

The Endorsements Worth Checking Beyond "Additional Insured"

SIMA's risk management guidance flags two more endorsements that rarely make it into a first-draft contract, but change who actually pays when something goes wrong:

• Waiver of subrogation. If both the property owner and the contractor share some fault for an incident, this endorsement waives the contractor's insurance carrier's right to pursue the property owner for their share of the negligence. Without it, your own liability exposure isn't fully transferred even if you were only partially at fault.
• Primary and non-contributory. This is the endorsement that decides whose policy pays first. Without it, both the contractor's and the property owner's carriers could end up splitting the defense, which is the opposite of what "risk transfer" is supposed to accomplish. With it, the contractor's policy responds first, and the property owner's own policy isn't drawn into the claim unless the contractor's coverage is exhausted.

None of these show up on a standard certificate of insurance. They only show up in the endorsement pages of the actual policy, which is why documentation that actually holds up in a slip-and-fall claim starts well before the first snowfall — it starts with the paperwork you require at signing.

The Coverage a Legitimate Snow Removal Contractor Should Carry

Per SIMA's contractor risk guidance, a properly insured commercial snow and ice operation typically carries four distinct coverages, each doing a different job:

• General liability — covers third-party bodily injury and property damage claims arising from the work itself, subject to the additional insured, waiver of subrogation, and primary/non-contributory endorsements above.
• Auto liability, including hired and non-owned auto coverage — standard auto liability covers company-owned trucks and plows. If the contractor uses subcontractors or rented equipment during a major event, hired and non-owned auto coverage is what protects against liability from a vehicle the contractor doesn't technically own.
• Workers' compensation and employer's liability — mandatory anywhere the contractor has employees, and per SIMA, there is no cap on what a workers' compensation policy may have to pay out for a work-related injury. This is also where a waiver of subrogation in favor of the additional insured typically gets attached.
• Excess or umbrella liability, written to "follow form" — extends higher limits on top of the underlying policies, on the same terms and conditions. A follow-form requirement matters because an umbrella policy with different terms than the underlying general liability policy can create coverage gaps exactly where you'd expect it to respond.

Ask to see all four, not just the general liability certificate. A contractor who can produce clean documentation for every layer is telling you something about how the rest of their operation is run.

Red Flags When a Contractor Can't Produce the Right Documents

A few patterns are worth treating as disqualifying, not just inconvenient:

• The contractor can only provide a certificate of insurance and pushes back on adding additional insured, waiver of subrogation, or primary/non-contributory language to the contract itself.
• The certificate lists a general liability policy with no snow or ice removal classification, or an exclusion carved out for snow and ice operations  a distinction SIMA specifically flags, since some carriers treat snow removal differently from general landscaping or property maintenance.
• There's no separate discussion of workers' compensation, especially for a contractor who says they'll bring on day-labor or subcontracted crews during a major storm.
• Umbrella coverage, if it exists at all, isn't confirmed to follow form with the underlying policies.

Any one of these is a reasonable question to ask before signing. More than one, on a property with real foot traffic, is a reason to audit the contract before committing another season to it.

Where This Fits Into the Rest of the Contract

Insurance requirements don't exist in isolation — they sit inside the same contract that defines who is actually responsible for snow removal on a commercial lease and what happens if the contractor fails to perform. A contract with airtight insurance language but no clear scope of service, or no enforceable remedy for a breach, still leaves gaps. Insurance protects you after something goes wrong; scope, response-time commitments, and breach language are what reduce the odds it goes wrong in the first place.

How Invictus Handles This on Every Contract

This is first responder work, and we treat the paperwork like it. Every Invictus contract is structured to name the property owner as an additional insured with the waiver of subrogation and primary/non-contributory language attached before the season starts, not negotiated after an incident. Our geo-fenced service records and timestamped documentation exist for the same reason: when a claim does land, the question shouldn't be whether coverage exists, it should already be answered.

That standard travels across our entire footprint — from Vancouver and the rest of British Columbia, down through Seattle, to Portland. One vendor, one insurance standard, the entire I-5 corridor. For properties where prevention matters as much as response, our LEED-compliant Easy Ice Melt system is deployed through the same first responder units that get us on-site fast when a storm hits.
