Alberta weather can take a toll on your home, especially the roof. You trust your shingles to hold up under the weight of winter, sleet, heavy rain, and wind. Hail seems less frequent, so its impact on your roof is often an afterthought. Experts say that needs to change. With shifting weather patterns and the inability to predict when and where hail will strike, it’s essential to be prepared.
Severe Weather Strikes Alberta
In 2021, The Insurance Bureau of Canada (ICB) put out a bulletin warning homeowners about an uptick in hailstorms. From 2010 to 2020, severe weather events hit Alberta more than any other region in Canada. Hail damage claims can be costly–running into the billions. Impact-resistant, class 4-rated shingles are the gold standard for protecting your home and your family.
Proven Protection Against Hail
Shingles are the first line of defence against the elements. Contractors and homeowners quickly realized shingles are not created equal. In 1966, the Insurance Institute for Business & Home Safety (IBHS) developed an industry-standard testing protocol — UL 2218 — designed to mimic the impact of hail or other objects, then rated accordingly.
- Class 1 – Withstands two hits in the same spot by a 1.25 diameter steel ball
- Class 2 – Withstands two hits in the same spot by a 1.50 diameter steel ball
- Class 3 – Withstands two hits in the same spot by a 1.75 diameter steel ball
- Class 4 – Withstands two hits in the same spot by a 2.00 diameter steel ball
Roofing products rated class 4 are the best protection against hail. These materials are proven to hold up in harsh conditions. But that’s just a baseline for many companies. Manufacturers have developed their own specialized technology to safeguard against extreme heat and cold, mould and algae, and fire, all with an eye on curb appeal.
Roofing Materials Have Become High-Tech
As weather events become more extreme and material costs and insurance go up, companies have turned to technology to help set them apart from competitors. And Albertans are reaping the benefits. The Alberta Allied Roofing Association (AARA) works with suppliers and manufacturers that have stepped up their shingle game.

How Do I Know If I Have Class 4 Shingles?
Unfortunately, you can’t determine the class of a shingle by looking at it. Hiring a contractor you trust is crucial. You should be able to work with them to determine the right product for your roof. AARA has put together a searchable network of Alberta-based manufacturers and contractors. We can connect you with professionals who are not only knowledgeable but certified to properly install class 4-rated roofing materials.
