In Alberta, high winds and sudden storms can give your roof a beating. Wind can cause damage to your roof, pulling shingles up and scattering them across your yard. Ignoring this damage can lead to costly leaks, structural issues, and potentially damage your neighbour’s property.
Knowing what to look for and how to respond will help protect your home before a small problem becomes a big expense.
How does wind cause damage to roof shingles?
The force and direction of the wind, the condition of your shingles, and even how they were installed all play a role in whether you end up with wind-damaged roof shingles.
- Wind speed and uplift: Strong gusts can create pressure that lifts shingles, loosening their seal. Once lifted, its far more likely the shingle will tear away completely. Shingles can start to lift in winds as low as 60 km/h, but widespread damage often occurs when gusts reach 90km/h or higher.
- Storm conditions: Heavy rain, hail, or flying debris add weight and impact that can rip shingles off or crack them beyond repair.
- Poor installation or aging shingles: Nails that miss the nailing strip, improper sealing, or shingles nearing the end of their lifespan make roofs more vulnerable.
In Alberta, high winds and sudden summer storms are a fact of life. According to the Alberta Wilderness Association, Southern Alberta is one of Canada’s windiest regions, and Calgary is the windiest large city in Canada.
Knowing how to spot the early warning signs of wind damage can save you from bigger repairs.
How to spot wind-damaged shingles
After a storm, start with a visual check from the ground or a safe vantage point. Common signs of wind damage on shingles include:
- Curled edges or loose tabs that don’t sit flat against the roof
- Missing shingles that leave bare patches exposed
- Exposed underlayment where the shingles have blown away
- Damaged soffit vents
- Cracked or gaping chimney flashing
You can also check for clues indoors:
- Water leaks in the attic
- Ceiling spots or staining on walls
- Unexplained drafts entering your home
Remember, shingles that weren’t sealed properly are vulnerable to future storms and are hard to spot. If you suspect your roof is becoming weathered but don’t know what to look for, book a roof inspection for peace of mind. The team at Knights Roofing can easily identify unsealed shingles and other problems that put your home at risk.
How to repair wind-damaged shingles

If the damage is minor—such as one or two missing shingles—repairs are usually straightforward. But when large sections are blown off, your home’s structure may be at risk. In these cases, professional repair is critical, and fast action can make the difference between a repair and a full replacement.
For long-term protection, material choice also matters. High-wind rated shingles and metal roofing provide added durability and are among the best roof shingles for high wind conditions. At Knights Roofing, we don’t just repair damage—we guide you on the best options to protect your home. With regular inspections and preventative maintenance from our team, you’ll have the peace of mind that your roof can withstand whatever Alberta’s storms bring.
Does home insurance cover roof damage from wind?
Homeowners’ insurance in Alberta will usually cover wind damage to your roof shingles, including damage resulting from wind, hail, or fallen tree branches.
However, if your shingles are damaged because they were poorly installed or have simply aged over time, insurance might not cover it.
If your roof leaks due to normal wear and tear, your home insurance will not cover the repairs because it is your responsibility to regularly inspect and maintain your roof.
Documentation is key to strengthening your claim and avoiding surprises. After a storm, take photos and videos of all visible damage, both inside and outside your home.
You can also schedule a professional inspection; roofers can provide the detailed reports insurance companies often require.
What to do if a neighbour’s property damages your roof
It’s not just shingles. High winds can also send trees, fences, or debris from a neighbour’s yard onto your roof. When this happens, here’s how to handle it:
Responsibility vs. negligence
Once an object crosses onto your property and causes a wind damage roof issue, it becomes your responsibility to address the repairs. However, if the damage resulted from your neighbour’s negligence—such as failing to maintain a rotting tree—your insurance company may pursue compensation from their provider.
Insurance considerations
Most homeowners’ policies cover sudden hazards like fallen trees or flying debris, but not damage tied to neglect or old roofing. Always check your policy and document everything with photos or videos before making a claim.
Inspection first
Never attempt storm damage roof repair before an inspection is complete. Insurance companies require a professional assessment before approving claims. A roof inspection from Knights Roofing ensures nothing is missed and gives you the documentation you need to move forward with confidence.
