- Enviroshake products had zero warranty claims after the 2010 Calgary hailstorm, one of Canada's costliest hail events with over 60,000 claims and $400 million in damage.

When it comes to your home, protection is everything - especially from the unpredictable forces of nature. Enviroshake roofing products have been awarded a Class 4 Impact Rating (UL 2218) - the highest impact resistance rating available for roofing materials. What does this mean for you? Simply put: a stronger roof and greater peace of mind.
What is a Class 4 Impact Rating?
Administered by Underwriters’ Laboratories (UL)—an independent, third-party testing organization—the UL 2218 test evaluates how well roofing materials stand up to impact forces, like hail. The testing is simple yet rigorous: a 2-inch steel ball is dropped from a height of 20 feet onto the roofing material. To earn a Class 4 rating, the product must show no signs of cracking or breakage after repeated impacts. This is the ultimate stress test for your roof.
In 2010, Calgary, Alberta was hit with a catastrophic hailstorm that brought hailstones nearly 4 centimeters wide, damaging vehicles, homes, and businesses. The result? Over 60,000 insurance claims and a staggering $400 million in damage—making it one of Canada’s costliest hail events to date, according to the National Insurance Bureau.
Despite the scale of destruction, Enviroshake products had zero warranty claims after that storm. That's the kind of real-world proof that reinforces what the lab tests already show: Enviroshake stands strong when it matters most.
