If you’ve shaken your ice scraper angrily at the sky this December, no judgment. It’s been rough this year. Heavy snow blanketed West Michigan before Thanksgiving, bringing record low temperatures with it. A freeze-thaw pattern followed over Christmas, and now we are back to sleet and snow. Unfortunately, for commercial property owners and facility managers, these winter conditions don’t just make life chilly or inconvenient, they create serious risks for water damage, ice intrusion, and even mold.
At John Grace, we’ve been helping businesses respond to winter-related property damage for decades. But the best response is often a preventative plan. Here’s how you can protect your commercial building this winter and how we can help when things go wrong.
The Real Risks of Winter Weather Damage for Commercial Buildings
Unlike single-family homes, commercial properties face unique challenges when it comes to winter-related damage. Larger roof spans, more complex plumbing, multiple tenants, and higher foot traffic can all increase exposure. Here’s what you should be watching for:
1. Ice Dams and Roof Leaks
When heat escapes from an inadequately insulated roof, it melts snow unevenly, causing water to back up behind ice dams and seep under shingles or other roofing materials. This can lead to:
- Ceiling leaks
- Wall damage
- Insulation saturation
- Mold growth in ceiling cavities
What to watch for: Look for icicles forming along the roofline, or water stains on the ceilings or near the tops of interior walls.
2. Frozen and Burst Pipes
Uninsulated plumbing in basements, stairwells, or external walls can freeze quickly during cold snaps. When they thaw, the resulting leaks can flood offices, classrooms, storage areas, or even server rooms.
What to watch for: Monitor underused areas of the building and check pipe temperature during extreme cold.
3. Ice Intrusion Around Doors and Windows
Gaps in seals or drainage issues can cause ice to build up around entrances, leading to both water intrusion and safety hazards for employees or customers.
What to watch for: Look for signs of frost inside window panes or water pooling near door thresholds.
4. Mold from Slow Leaks or High Humidity
Water intrusion often leads to hidden moisture in drywall, carpet, or subfloors. Combined with poor winter ventilation, that sets the stage for mold growth. This can be common in utility closets, basements, and break rooms. None of these areas are typically designed with active airflow or humidity control in mind, and mold spores thrive in stagnant air, especially when moisture builds up.
What to watch for: Schedule regular checks and consider installing small dehumidifiers or sensors to catch moisture early.
Commercial Properties at Highest Risk
- Schools and universities (aging buildings, infrequent winter use of some areas)
- Apartment complexes (multiple units and common area pipes)
- Warehouses and manufacturing plants (large, unheated spaces)
- Office buildings (frequent HVAC cycling and multi-zone systems)
- Retail spaces (high foot traffic, frequently used entry points)
