Winter does not forgive a facility that walked into November unprepared. A single frozen sprinkler riser can flood two floors; a boiler that nobody tested in October trips the first week it gets below zero; a flat roof under 24 inches of wet snow is a structural problem, not a cosmetic one. This winter facility maintenance checklist walks the four fronts — freeze prevention, boiler and hydronic systems, roof and snow load, and the exterior grounds — so nothing waits for a 3am call to find out it was skipped. OXMAINT AI is the AI-powered facility maintenance management software that holds the whole winter checklist on one register, assigns each item to a technician, time-stamps the closeout, and shows the readiness score live.
Four fronts, 48 items. Freeze prevention, boiler & hydronic, roof & snow load, exterior & grounds. Tick each one as a native checkbox, assign it in OXMAINT AI, close it with a photo. The building is winter-ready before the first below-freezing night, not after it.
Freeze damage follows a predictable timeline. The outside temperature does not need to be sub-zero for days — a long single night at 20°F / -7°C with wind, on an un-insulated riser or a dead-leg pipe, is enough. OXMAINT AI pushes the checklist 72 hours before the first forecast freeze so the building has a window.

On-call engineer with heat-trace monitoring and a dry-pipe sprinkler audit route.
A boiler failure in January is a measurable guest-, patient- or occupant-impact event. Twelve items catch the usual causes before the first below-freezing night.
Section 3 · Roof & Snow Load Checklist
A flat roof is a snow collector. Twelve items keep it from becoming a structural concern.
The last twelve items cover the ground around the building and the backup systems that run when primary ones fail.
Winter Reference Numbers Worth Pinning
Three reference numbers settle most on-the-fly winter decisions. OXMAINT AI holds them on the asset record so the engineer finds them without hunting.
FREEZE-STAT SET POINT
38 – 40°F
(3–4°C)
AHU coil freeze protection trip. Below this at the coil face, the AHU fan is cut and OA damper is closed.
VACANT SPACE MINIMUM
55°F
(13°C)
Minimum thermostat setting for any vacant tenant space with water piping on the exterior wall. Non-negotiable.
ROOF SNOW CLEARANCE
6-8 in
dry snow
Trigger for roof snow removal on most flat-roof commercial buildings; wet snow trigger is lower. Confirm against the roof design snow load.
Winter Readiness Scorecard — Live From The Checklist
As each item is ticked and closed in OXMAINT AI, the readiness score rebuilds live. The facility manager sees exactly which section is holding the building back from fully winter-ready.

A Burst Pipe Costs More Than The Full Winter Program.
One frozen 4-inch wet sprinkler riser, two floors flooded, three weeks of restoration. The winter checklist is small money against that. OXMAINT AI holds the checklist, assigns the walk, logs the closeout and surfaces the score live.
The 48-item winter checklist, the forecast-triggered freeze protocol, the readiness scorecard, the asset-level logs and the emergency contact tree all live in the OXMAINT AI facility maintenance management software — open an account and load the winter checklist on OXMAINT AI today.
Forecast-Triggered Checklist
Freeze forecast at T-72 h fires the walk automatically; nothing waits for someone to remember to run it.
Mobile Walk Mode
Each item ticks on the engineer's phone with a photo and a timestamp; walking the roof means walking the checklist.
Readiness Scorecard
Live percentage by section — freeze / boiler / roof / exterior — so the lagging front is visible without a meeting.
Freeze Alarm Routing
Low-temp sensor on BMS raises a P1 WO with escalation to on-call engineer and property manager within one minute.
Compliance Logs
Boiler combustion logs, LWCO tests, water chemistry results and sprinkler-riser temperature audit trail retained per inspection cycle.
The full 48-item walk belongs in October, before the first freeze window. OXMAINT AI re-fires the freeze-prevention section automatically at T-72 h of any forecast freeze through the season, so nothing slips once the walk is done.
Do we really need to test a freeze stat if it worked last winter?
Yes. Freeze stats fail quietly — a stuck mechanical bulb or a drifted electronic probe does not announce itself. The manual trip at the beginning of each heating season is the only confirmation they still work.
What's the minimum snow depth that triggers roof clearance?
On most flat commercial roofs, 6-8 inches of dry snow or 3-4 inches of wet snow is the trigger. The real answer is the roof's documented design snow load divided by the snow density — a number OXMAINT AI keeps on the asset record so the engineer finds it without hunting.
Does the readiness scorecard replace a walk-through?
No. The scorecard verifies that the walk happened and shows what is open. The walk itself is the work. OXMAINT AI mobile mode is how the walk gets done — one checkbox per item, with a photo per asset.
Winter-Ready, Not Winter-Surprised.
Load the 48-item winter checklist into the OXMAINT AI facility maintenance management software — forecast-triggered freeze walk, mobile ticking with photo, readiness scorecard, freeze alarm routing. The building is winter-ready before the first freeze, not after it.
