When it comes to protecting your home from Calgary’s unpredictable weather—think hail, high winds, and heavy snowfall—your choice of roofing materials matters. If you’re weighing Class 3 vs. Class 4 shingles, understanding the difference in impact resistance can help you make the right decision for long-term durability and peace of mind.
What Do Class Ratings Mean?
Shingle impact resistance is rated on a scale from Class 1 to Class 4, based on how well the material withstands impact from a steel ball dropped from varying heights. This testing method, known as UL 2218, helps determine how likely a shingle is to resist cracking or breaking under impact.
- Class 3 Shingles: Tested to withstand a 1.75-inch steel ball dropped from 17 feet.
- Class 4 Shingles: The highest rating available, can take a hit from a 2-inch steel ball from the same height without showing visible damage.
While both offer strong protection, Class 4 shingles are designed to be significantly more durable, especially in regions like Calgary, where severe hailstorms are common.
Let’s Compare: Class 3 vs. Class 4 Shingles
When comparing Class 3 and Class 4 shingles, there are a few key differences to consider. In terms of impact resistance, Class 3 shingles perform well, but Class 4 shingles offer excellent protection, especially in extreme conditions. Durability during hailstorms also sets them apart—Class 3 shingles can withstand moderate hail, while Class 4 shingles are built to endure more severe impacts without damage.
You may also see a difference when it comes to insurance discounts. Some providers offer discounts for Class 3 shingles, but Class 4 shingles more often qualify for significant insurance savings due to their higher rating.
In terms of cost, Class 3 shingles are generally more affordable upfront, while Class 4 shingles require a higher initial investment. However, Class 4 shingles often make up for it with their extended lifespan, which can exceed 30 years, compared to the 20 to 25 years typically expected from Class 3 products.
If you’re trying to balance budget and protection, Class 3 shingles are still a reliable option. However, if your priority is reducing future maintenance, avoiding insurance claims, and extending your roof’s lifespan, Class 4 shingles are worth the investment.

Calgary residents know how damaging hail can be. In fact, the city is one of Canada’s hailstorm hotspots. Choosing impact-resistant shingles is not just about preventing immediate damage—it’s about minimizing long-term costs for shingle repairs, insurance claims, and premature replacements.
