Ottawa homeowners know that winter here is more than just cold—it’s relentless. Heavy snowfalls, ice dams, and freeze-thaw cycles put extraordinary stress on residential and commercial roofs every year.
Without proper maintenance, these conditions can shorten the lifespan of your roof, lead to costly repairs, and compromise the safety of your home.
At Godfrey Roofing, we’ve been protecting Ottawa properties since 1984, and we understand exactly how our climate impacts roofing systems—and how to prevent damage before it happens.
How Snow Accumulation, Ice Dams, and Freeze-Thaw Cycles Damage Roofs
Snow may look picturesque, but when it piles up on your roof, it becomes a serious hazard. A cubic metre of packed snow can weigh more than 50 kilograms, and ice is even heavier. This weight stresses structures, especially older ones, and can cause sagging or even collapse in extreme cases.
Ice dams are another common winter problem. They form when heat escaping from your attic melts the snow, which then refreezes at the eaves. This ridge of ice blocks proper drainage, forcing water back under shingles and into your home. Left untreated, ice dams can cause leaks, warped wood, and interior water damage.
Freeze-thaw cycles add another layer of risk. Ottawa’s fluctuating winter temperatures cause snow and ice to melt during the day and refreeze at night. This repeated expansion and contraction loosens shingles, cracks flashing, and opens pathways for water infiltration.
Impact on Different Roofing Materials
Not all roofing materials respond to Ottawa’s winters the same way:
- Asphalt shingles: The most common in Ottawa, asphalt shingles are vulnerable to cracking and curling during freeze-thaw cycles. Ice dams can lift shingles, exposing the underlayment to moisture and potential damage.
- Cedar shakes: Cedar is durable and attractive, but it’s porous. Freeze-thaw cycles can cause cedar to absorb water, leading to warping and rot if not properly maintained.
- Metal roofing: Metal roofs shed snow more easily, reducing the risk of accumulation. However, they can still experience ice damming at the eaves and require proper insulation and ventilation to prevent condensation.
Choosing the right material is important, but professional installation and maintenance are what truly determine how well yours withstands Ottawa’s winters.
Signs of Winter Damage
Homeowners should watch for these warning signs during and after winter:
- Leaks or water stains on ceilings and walls
- Warped or sagging roof decking
- Missing, cracked, or curled shingles
- Excessive icicles forming along the eaves
- Unusual creaking or shifting sounds during heavy snowfalls
Ignoring these signs can lead to more extensive damage and higher repair costs down the road.
Immediate Steps Homeowners Can Take to Minimize Damage
While Ottawa winters are unavoidable, homeowners can take proactive steps:
- Clear snow safely: Use a roof rake from the ground to remove excess snow.
- Improve insulation and ventilation: Proper attic insulation reduces heat loss, minimizing ice dam formation. Ventilation helps regulate the temperature and moisture levels.
- Clean gutters before winter: Blocked gutters prevent proper drainage, increasing the risk of ice dams.
- Schedule a professional inspection: A pre-winter inspection can identify vulnerabilities before they become major issues.
Importance of Professional Roof Maintenance & Snow/Ice Removal Services
