That first heavy snowfall in Ontario can be magical—but it’s also the ultimate test for your roof. Many homeowners don’t realize there’s a problem until melting snow creates leaks, ice dams, or sagging ceilings.
One Kitchener family learned this the hard way when their roof started leaking just days after the first snowstorm. With the right preparation, you can avoid the same fate.
Why the First Snowfall Matters
- Sudden Weight Load: Snow is heavier than it looks. Even a few inches can strain weak spots.
- Ice Dams: Heat escaping from your home melts snow, which refreezes at the eaves, trapping water.
- Hidden Leaks: Cracks and missing shingles quickly reveal themselves under snow.
How to Know if Your Roof is Ready
- Check Attic Insulation and Ventilation
Poor insulation causes uneven melting, leading to ice dams. Proper ventilation keeps temperatures balanced. - Look for Damaged Shingles
If shingles are curling, cracked, or missing, they won’t stand up to snow and ice. - Inspect Flashing Around Vents and Chimneys
These are common leak points when snow starts to melt. - Assess Gutter Health
Snowmelt needs somewhere to go. Clogged gutters mean water backing up under shingles. - Consider Roof Age
Roofs over 20 years old are much more vulnerable under heavy snow.
Quick DIY Test For You To Try
Stand in your attic during daylight. If you see sunlight shining through cracks, snow and water will make their way in too.
