Our province experiences several snowstorms and winter storms every year. A winter storm is considered more dangerous, with more than 25 centimetres of snow accumulation in less than 24 hours, with a combined effect of several weather conditions such as strong winds, blizzards and blowing snow.
Snowstorms and winter storms
In winter, snowstorms and winter storms dump several tens of centimetres of snow in just a few hours. They can be accompanied by strong winds and other harsh conditions. Several actions must be taken before and quickly after the storm to protect your home, particularly from risks of water infiltration and weight of snow.
Tips to prevent damage caused by water infiltration and snow weight
- Clear and de-ice sidewalks, stairs and entrance of the house.
- Remove snow from the gas or electric meter, the outdoor heat pump, the vents of gas appliances and ventilation.
- Remove snow from basement windows and foundation base as needed to prevent water infiltration as the snow melts.
- After a heavy accumulation of snow, clear the roof or have it done by a specialized contractor.
- Check that your heater, wood stove and other heating sources are in good working order. Have them inspected, maintained and cleaned. During the winter, clean or replace the heater's air filters as needed.
- If you are away for a few days, leave the heating on (at least 12°C) and designate a trusted person to check your home while you are away.
- Run water through all water pipes regularly. Prevent piping from freezing by installing an insulating sheath on exposed pipes.
- Inspect your attic for frost build-up and make sure gutters and roof don't have ice dams or ice cubes.
- Cut down tree branches that are near the house, roof, windows and electrical wires.
