As the temperatures drop and the days grow shorter across North America, facility managers and building owners know what time it is — winter prep season. Whether you're managing a commercial building, multi-family property, or industrial facility, preparing your site for the cold months ahead is not just smart — it’s essential.

A thorough end-of-year building maintenance checklist can save you thousands of dollars in emergency repairs, reduce energy costs, and help keep occupants safe and comfortable. In this post, we’ll break down a comprehensive winter building preparation guide tailored for property professionals across the U.S. and Canada — and how platforms like Onsite HQ can streamline the process with digital checklists and inspections.

Why Winter Preparation Matters

North American winters can be brutal, with snow, ice, and freezing temperatures wreaking havoc on unprepared buildings. Every year, facility teams deal with:

• Frozen or burst pipes
  
  
• Roof damage from snow accumulation
  
  
• HVAC system failures
  
  
• Slips and falls due to icy walkways
  
  
• Skyrocketing heating costs
  
  

The best defense? A proactive end-of-year checklist that covers all the critical systems and potential risk areas in your building.
