We may have gotten lucky this hurricane season, but as every property manager knows, Mother Nature has her own schedule. Each season brings new challenges—especially winter. Freezing temperatures, snow loads, ice dams, and high winds can all cause significant damage to a commercial roof. Weatherproofing your roofing system before the cold sets in can make the difference between an uneventful season – and costly emergency repairs.

Weatherproofing Tips Before the Storm

Schedule a Comprehensive Roof Inspection: The first step in winter weatherproofing is a professional roof inspection. Even small vulnerabilities can escalate once temperatures drop. Cracked membranes, loose flashing, or clogged drains may not seem serious in the fall, but when water freezes and expands, those minor issues can quickly turn into leaks or structural damage. A licensed roofing contractor can identify early warning signs and recommend necessary repairs. Focus areas should include:
- Flashing and sealants
- Membranes and seams
- Drainage systems
Clean and Clear the Roof: Leaves, debris, and standing water can trap moisture and add unnecessary weight to your roof. Before winter sets in, make sure your roof surface and drainage components are clean. Standing water is especially concerning for flat or low-slope roofs—it can freeze, add weight, and eventually cause structural strain. If there are trees in close proximity to your building, schedule routine cleanings throughout the fall season to ensure their health and safety. Installing gutter guards or strainers in drains can also prevent future blockages.
Insulate and Seal Penetrations: Proper insulation and sealing are key to preventing heat loss and ice dam formation. When warm air escapes from inside the building and melts snow on the roof, it can refreeze along the edges, creating heavy ice dams that block drainage and lead to leaks. Inspect insulation and repair any compromised sections. Seal all roof penetrations—such as vents, pipes, and HVAC curbs—to prevent heat transfer and moisture intrusion.
Check for Structural Integrity and Snow Load Capacity: Winter storms can dump heavy, wet snow that tests a roof’s load-bearing limits. Knowing your roof’s weight capacity and having a snow removal plan in place is critical. If your building has experienced roof ponding or sagging in the past, have a structural engineer evaluate the roof before winter begins. Roof snow should be cleared evenly to prevent uneven stress and avoid damaging membranes.
Reinforce Roof Coatings and Membranes: Elastomeric or silicone roof coatings can provide an additional layer of protection against snow, ice, and wind. These coatings improve waterproofing, reflectivity, and temperature regulation—helping extend the lifespan of your commercial roof. Recoating your roof is a relatively quick process that adds substantial value and resilience.
Maintain HVAC Units and Rooftop Equipment: Rooftop equipment is another weak point during winter storms. Loose panels or damaged mounts can create openings for water infiltration or become hazards in high winds. Have all rooftop mechanical systems inspected and tightened, and verify that condensation lines are properly insulated and draining away from the roof surface.
Create a Winter Maintenance Plan: Finally, don’t wait until there’s snow on the roof to plan your response. Establish a winter maintenance schedule that includes routine inspections after major storms. Keep your roofing contractor’s contact information handy, and document all maintenance and repairs for warranty purposes.
