A slip-and-fall claim is not won by proving you did a good job. It is won — or lost — on whether a contemporaneous record shows that a reasonable operator, following the contract, serviced the property at a documented time with documented materials. The contractors who lose these are rarely the sloppy ones on the lot; they are the ones who cannot produce paper.
This is general information for snow and ice contractors, not legal advice. Liability standards, statutes of limitations, and "storm in progress" rules vary widely by state and province and change over time. Use this to organize your documentation, and use a licensed attorney in your jurisdiction for anything specific to a contract or a claim.
The standard, in plain language
You are generally not an insurer of the property — you are not required to guarantee that no one ever slips. In most jurisdictions the standard is reasonable care: given the conditions and your contract, did you act as a reasonable snow professional would? That framing matters, because it means your defense is not "the lot was perfect" (it never is during a storm) but "we did what was reasonable and here is the record proving it."
The corollary is that reasonableness has to be demonstrable. A jury or an adjuster cannot see the care you took on a January night months ago. They can only see the documents. No documents, and your reasonable care effectively did not happen for legal purposes.
What the other side asks for first
When a demand letter arrives, the plaintiff's attorney does not ask whether you are a good contractor. They send a request for records, and the list is predictable: the service contract, your service records for that site, material/salt logs, any photos, and the weather data for the incident window. What you can produce — and how contemporaneous it looks — largely decides how the claim goes.
The tell that wins or sinks cases is timing. Records generated in the ordinary course of business, at the time of service, are credible. Records that were obviously assembled after the demand letter — a clean spreadsheet with no time stamps, filled in from memory — invite the argument that they are reconstructed and unreliable. Build the habit of capturing the record as the work happens, because you cannot manufacture credibility later.
The five documents that defend a claim
These are the records that carry weight, in the order they tend to matter:
- The signed contract — defines what you were obligated to do and when. Its scope and trigger language is your first line of defense (below).
- Per-visit service records — time in and time out for every visit, the service performed, and which crew. This is what puts you on the property at a known time relative to the fall.
- Material logs — what you applied (salt, treated salt, chloride) and how much, tied to the visit. Quantities matter; "we salted" is weaker than "we applied 400 lb of treated salt at 6:10am at 22°F pavement."
- Photos — timestamped, ideally geotagged, before and after service. A photo of a cleared, treated surface at a known time is hard to argue with.
- Weather records — official station data from your national weather service, or another documented weather source, showing what was falling and when. This anchors the "storm in progress" question and shows conditions were beyond a single visit's control.
Contract language is a liability document, not just a price
Most of your legal exposure is decided before the season starts, in the contract. Three clauses do the heavy lifting:
- Trigger depth — the accumulation at which you are obligated to respond (e.g., service begins at 5 cm / 2"). This defines when your duty starts, so a fall at a 1 cm dusting is measured against an obligation that had not triggered.
- Scope boundaries — exactly which surfaces you service. If sidewalks, loading docks, or a garbage enclosure are the property owner's responsibility, say so in writing. A huge share of claims happen on the square footage nobody agreed to own.
- Storm-in-progress / continuing-storm language — many jurisdictions recognize that you cannot keep a surface bare mid-storm and that a reasonable interval after snowfall stops is allowed before cleanup. Whether and how this applies varies by jurisdiction; reflect it in the contract and confirm the local rule with counsel.
The gap between your last documented service and the incident is one of the first things examined. If someone falls two hours into an active storm, your trigger and continuing-storm language plus a weather record showing snow still falling is a coherent defense. If they fall on clear ice eight hours after your last visit on a dry night, that is a different and harder conversation — which is why refreeze and re-check obligations belong in the contract too.
Retention and how to actually capture it
Keep every record for at least the statute of limitations window for personal-injury claims in your jurisdiction — which is often a few years and sometimes longer, so confirm the number locally rather than guessing. A claim can land long after the season you have already mentally closed. Purge too early and you have destroyed your own defense.
The practical failure is not deciding to document — everyone agrees they should. It is that a driver at 3am in a storm will not fill out a paper form accurately, so the record either never exists or gets faked up later. The fix is to make capture happen at the point of work: the driver marks time in and out, logs material, and shoots before/after photos from the truck, and the timestamp and location come from the device automatically. When the service record is created the instant the work finishes, it is contemporaneous by construction — and that is exactly the quality of record that survives a claim.
Frequently Asked Questions
Am I automatically liable if someone falls on a property I service?
No. In most jurisdictions you are held to a reasonable-care standard, not a guarantee that no one ever slips. The question is whether you did what a reasonable snow professional would given the conditions and your contract — and whether you can document it. This is general information, not legal advice; confirm the standard where you operate.
How long should I keep snow service records?
At least as long as the personal-injury statute of limitations in your jurisdiction, since a claim can be filed well after the incident. That window varies, so verify the number locally and keep contracts, service records, material logs, photos, and weather data for the full period.
Does a signed contract protect me from slip-and-fall claims?
A well-written contract helps a great deal because its trigger depth and scope language define what you were obligated to do and when — but it does not make you claim-proof. It works together with contemporaneous service records; the contract sets the duty, the records show you met it.
What is the "storm in progress" or continuing-storm rule?
Many jurisdictions recognize that a contractor cannot keep surfaces bare during an active storm and allow a reasonable interval after snowfall ends before cleanup is expected. Whether it applies and how it is defined varies significantly by location, so treat it as a reason to keep good weather records and to confirm the local rule with an attorney.
Are phone photos good enough as documentation?
Yes, when they are timestamped and ideally geotagged, and taken before and after service at each visit. A clear, time-stamped photo of a serviced surface is strong evidence. The weakness is not the camera — it is photos taken inconsistently or only after a claim, which read as reconstructed.
