Owning a home in London, Ontario, has its perks, but the weather sure isn’t one of them. One day you’re soaking up sunshine, and the next you’re facing snow, freezing rain, or humidity so thick it feels like you’re walking through soup. This unpredictable climate doesn’t just affect your plans—it takes a toll on your roof.
Many homeowners call us at AM Group Exteriors after dealing with leaks, worn-out shingles, or ice dams, wishing they had chosen a more durable roofing material. The truth is, selecting the right roof for London’s wild weather isn’t about following trends—it’s about survival and long-term protection.
Why London, Ontario’s Weather Demands Smarter Roofing Choices
If you’ve lived here long enough, you already know the extremes:
- Heavy snowfalls and sudden thaws
- Weeks of bitter cold
- Blazing sun and high humidity in summer
- Strong winds and the occasional hailstorm
These conditions put tremendous stress on your roof. Freeze-thaw cycles alone can crack and weaken older materials, while moisture from rain or wet leaves often leads to leaks, rot, and mould. Choosing the right roofing material means choosing one that can handle these ups and downs without constant repairs.
The Most Common Roofing Materials in London
Not every material suits every home. What works for your neighbour’s bungalow may not be the best fit for your two-storey. Here are the top options and how they hold up against London’s climate:
| Material Type | Weather Performance | Lifespan | Maintenance Level | Affordability |
| Asphalt Shingles | Good | 15–30 years | Low | Budget-friendly |
| Metal Roofing | Strong | Varies | Low | Higher upfront |
| Wood Shakes | Fair | 20–40 years | Moderate to High | Premium price |
| Synthetic Shingles | Strong | Varies | Low | Mid to high |
Not every material is ideal for every home, and what you choose depends on things like your budget, the age of your house, the slope of your roof, and how long you plan to stay there.
Asphalt Shingles: Still a Local Favourite
Affordable and versatile, asphalt shingles remain one of the most popular choices for London homeowners. They perform well in mixed weather, especially when installed properly by experienced roofing companies in London. The trade-off? Over time, they can wear down from UV rays and moisture. Regular roof repair services help extend their lifespan.
Metal Roofing: Built for Extremes
After snowstorms, many homeowners ask about metal roofs. Snow slides off easily, and metal handles wind and rain exceptionally well. While the upfront cost is higher, the longevity and low maintenance often balance the investment if you plan to stay in your home long-term.
Wood Roofing: Rustic but High-Maintenance
Wood shakes offer charm and natural beauty, but they need care—especially in London’s damp climate. Without consistent upkeep, they’re prone to mould, mildew, and rot.
Synthetic Options: Modern Strength with Style
Synthetic roofing materials mimic the premium looks of slate or wood but are made with modern composites. They’re lightweight, durable, and generally more resistant to weather. For homeowners who want curb appeal without constant upkeep, this option is worth considering.
Beyond Materials: What Really Impacts Your Roof’s Performance
The material you choose is only part of the equation. To avoid future headaches, consider:
- Roof Slope: A steep roof sheds snow easily, but may not work with all roofing types.
- Ventilation & Insulation: Even the best roofing materials fail if your attic isn’t vented. Poor airflow leads to ice dams, moisture, and shingle damage.
- Local Conditions: From falling branches to raccoons, London roofs face unique challenges. Choosing a roof that works with your surroundings is key.
