National snow management subcontracts: what their COI demands, line by line

The honest answer is that the exhibit is a list of endorsements, not a list of certificates. A certificate can only show what the policy already has, and a national snow management firm’s insurance exhibit is asking for six or seven things that live on the policy as endorsements, plus an indemnity clause that lives in the contract. If the policy wasn’t built for them in September, the certificate can’t say they’re there in November. That’s the whole article, and it’s why commercial snow and ice operators who sub for national firms need the packet read before the season, not the week a truck is due on the lot. Here’s the exhibit, line by line, with what each line is really asking for and where it has to live.

How the packet works

Two things to understand about the paper. The firm doesn’t own the lot. It holds a master contract with a retailer, a distribution center, a bank chain, or a property owner with a hundred sites, and that master contract sets the insurance terms. Your subcontract passes those terms down. The exhibit you get for a big-box lot off I-25 in Denver is the same exhibit a sub gets for a lot outside Columbus, because it was written once for every sub in every state.

That means it’s rarely negotiated, and it’s not written for a Colorado operator with a loader and two trucks. It’s written to protect the firm and its client from you. None of that is a complaint. It’s the reason you read every line before the portal check-in starts.

The exhibit, line by line

General liability limits, with snow named

The limits line is usually $1M per occurrence and $2M aggregate, sometimes with a per-project aggregate. The part people skip is the sentence after the limits: the certificate has to show that snow and ice removal operations are covered, or that no snow and ice exclusion applies. A landscaping GL with a snow exclusion endorsement fails this line no matter what the limits say. The general liability page covers classifications; the seasonal snow policy article covers what a short-term certificate does to this line.

Additional insured, ongoing and completed operations

The firm, its client, the property owner, the landlord, and “all others as required by written contract” want to be additional insureds on your GL. That takes an endorsement on the policy; the certificate only reports it. Most exhibits want it on a blanket basis, so every party the contract names is picked up automatically, and they want both ongoing operations and completed operations, which are two separate endorsements under most standard forms. The additional insured article explains the difference between a holder and an insured. Short version: an additional insured can tender a claim to your policy, and that’s the point.

Primary and non-contributory

This line says that when a tenant falls on the lot and sues everybody, your policy pays first and the firm’s policy doesn’t chip in. It’s endorsement wording, not certificate wording. Some GL forms carry it by default for additional insureds where a written contract requires it; some need a separate endorsement; a few carriers won’t give it for snow at all. The GC requirements article walks the same clause on a construction exhibit, and it reads the same here.

Waiver of subrogation, on three policies

The exhibit will ask for a waiver of subrogation on GL, auto, and workers’ comp. A waiver means your carrier gives up the right to go after the firm to recover what it paid you. On comp it’s an endorsement the carrier commonly offers on a blanket basis; on GL and auto the same. It’s usually available. The question is whether it’s already on the policy when the request lands.

Umbrella or excess

Above the GL, most exhibits ask for excess limits. A $5M ask on a distribution center lot is not unusual, and the exhibit usually requires the umbrella to follow the same additional insured and primary wording as the GL and to schedule the GL, auto, and employer’s liability underneath it. The umbrella page covers follow-form versus stand-alone; the practical point is that an umbrella bought before the exhibit was read often doesn’t schedule the right underlying policies.

Commercial auto

Usually $1M combined single limit, with hired and non-owned auto included and the firm as an additional insured on the auto policy too. Colorado requires minimum auto liability limits of $25,000 per person and $50,000 per accident for bodily injury and $15,000 per accident for property damage (C.R.S. 10-4-620; 42-7-103(14)(a)), unchanged as of 2026; commercial contracts commonly ask for $1,000,000 combined single limit instead. (C.R.S. 10-4-620; 42-7-103(14)(a)) A plow truck legal at the state minimum fails this line on the first read. If a crew member drives their own pickup between lots, hired and non-owned is the line that covers it, and the commercial auto page covers the plow disclosure.

Workers’ compensation and employer’s liability

Statutory comp, employer’s liability at the limits the exhibit lists, and the waiver above. A sole proprietor with no employees will get asked for a certificate anyway; the exhibit doesn’t know Colorado’s owner rules, and the workers’ compensation page explains the election. If you bring a helper for the big storms, that helper is an employee.

Notice of cancellation

The exhibit wants 30 days’ written notice to the firm if any policy cancels. The certificate can’t grant that; the standard form says notice follows the policy provisions, and nothing more. What can grant it is a notice-to-designated-entity endorsement, if the carrier offers one and for however many days it offers. Some firms accept the standard certificate wording; some won’t release the site until the endorsement is on file. What we don’t control is the carrier’s answer. Ask for it in September.

The indemnity clause

This is in the contract body, not the exhibit, and it’s the widest thing in the packet. Typically you agree to defend and hold harmless the firm and its client for any claim arising out of your work, and often for claims arising out of their own acts too. Your GL typically responds to indemnity you took on for your own work through contractual liability coverage; whether it responds to indemnity for the firm’s negligence depends on the form and the carrier’s read. Colorado narrows one piece of it. Colorado's Snow Removal Service Liability Limitation Act (C.R.S. 13-21-129, effective August 8, 2018) voids any snow-and-ice contract clause that requires one party to indemnify, hold harmless, or defend the other for the other party's own acts or omissions, but only where the service provider was prohibited, by the contract or in writing, from mitigating the specific snow or ice event at issue. (C.R.S. 13-21-129(3), (4); SB 18-062)

That matters on a national account more than on an HOA, because the firm’s portal is where instructions live. “Service on request only.” “No de-icer on the new concrete.” “Do not plow the rear lot.” Our read is that a written instruction in the portal is a writing under the act, and that a private commercial lot is inside the statute while a contract with a city or other public body is not. That read is ours as contractors and agents; confirm it with a Colorado construction attorney before you rely on it.

The documentation demands

GPS-tracked trucks, time-stamped photos at arrival and departure, portal check-in and check-out, product logs by site. None of that is insurance. All of it is what a slip-and-fall gets decided on eight months later, and the slip-and-fall article explains why the log beats the memory. Treat the portal as your defense file.

Where each line has to live

The certificates page explains what to send us when the request arrives. The exhibit itself, not a summary of it.

Where to go from here

If a national firm’s packet is sitting in your inbox, send the exhibit and the contract to us before you sign, through the certificates page, and we’ll mark each line against the endorsements on your policy. Already subbing and not sure the last certificate was true? The policy review reads your dec pages against the table above. The commercial snow and ice page covers what the underwriter asks about lot type, ice in scope, and logs. The HOA contracts article is the smaller version of this exhibit, with a board on the other side. An upslope storm, sun at noon, and a refreeze at dusk on a Denver lot don’t wait for the endorsement to come back. September is the month. No online quote, on purpose.
