Impact of Snow and Severe Weather on the Energy Performance of Buildings
February 17, 2026
The Canadian winter can be harsh on commercial and industrial buildings. Snow, ice, and temperature fluctuations are not only a challenge for the safety and durability of your roof: they can also affect the energy performance of your facilities.
1. The insulating effects of snow and its limitations
Snow accumulated on a roof can act as a natural insulator, temporarily reducing heat loss. However, this protection is often uneven:
- Areas where snow melts faster can form thermal bridges.
- A layer that is too thick can overload the structure and cause damage that compromises energy efficiency.
2. Water infiltration: a direct impact on energy consumption
Melting snow and rain can cause water infiltration if a roof has gaps or cracks. Moisture that seeps into the insulation or structure reduces its thermal properties, resulting in:
- Increased energy consumption for heating.
- Cold spots in the building, affecting the comfort of occupants.
To prevent these problems, regular and professional maintenance is essential: discover our roof repair and roof inspection services.
3. The effect of temperature variations
Repeated freeze and thaw cycles damage the covering and membrane of a roof. These micro-cracks, invisible at first, can:
- Allow heat to escape from the building.
- Force heating systems to work harder, increasing energy costs.
4. The importance of preventive maintenance
Regular maintenance helps limit the negative effects of snow and winter weather:
- Safe snow removal to prevent overload and infiltration.
- Verifying insulation and sensitive areas to maximize energy efficiency.
Conclusion
Snow and severe weather conditions do not just cause aesthetic or structural problems: they can directly affect your building’s energy performance. Investing in preventive maintenance and monitoring of your roof not only protects your facilities, but also reduces your heating costs and ensures the comfort of your occupants.
