Alberta Winter is Coming !
Alberta winters can dump 2-4 meters of snow and bring temperatures as low as -40°C. Proper preparation now can prevent thousands in damage and emergency repairs later.
Alberta’s winters are among Canada’s harshest, with extreme temperature swings, heavy snow loads, and ice formation that can damage even well-built roofs. This comprehensive guide covers everything Alberta homeowners need to know about preparing their roofs for winter.
Understanding Alberta's Winter Challenges
Alberta’s unique geography creates extreme winter conditions that put roofs to the test:
- Heavy Snow Loads: 2-4 meters of annual snowfall in many areas
- Temperature Extremes: From +15°C to -40°C in a single winter
- Chinook Winds: Rapid thaw-freeze cycles creating ice dams
- Prolonged Cold: Months of sub-zero temperatures
