Hail Resistant Metal Roofing Systems
UL 2218 Class 4 — the highest impact rating available
Hailstorms Are Getting Worse — Is Your Roof Ready?
Across North America, homeowners are facing the harsh reality of increasingly frequent and severe hailstorms. From the plains of Texas to the suburbs of Minnesota, and from the wide skies of Alberta to the valleys of Oregon, these intense weather events are becoming more common and more destructive. Hail damage is responsible for billions in property damage each year — and one of the first casualties is your roof.
That's why more homeowners are making the switch to Interlock® Metal Roofing — a system designed to withstand hail, wind, and extreme weather, and still look beautiful year after year.
Why Interlock Is the Best Hail Resistant Roof on the Market
UL 2218 Class 4 Impact Rating
The highest hail resistance rating available — proven against golf-ball-sized hail without cracking, splitting, or denting.
Won't Rust, Crack, or Warp
Unlike steel or asphalt, aluminum won't rust and doesn't absorb moisture — ideal for hail-prone and cold-weather climates.
4-Way Interlocking Design
Each panel is secured on all sides, giving your roof unmatched strength against wind-driven hail and severe storms.
Energy-Efficient & Solar Compatible
Reflects heat in summer, sheds snow in winter — and ready for solar installation.

FAQs About Hail Roofing
What does "Class 4 impact resistance" mean?
It’s the highest rating under the UL 2218 test, meaning the roof can withstand a 2-inch steel ball dropped from 20 feet — simulating large hail impact without damage.
Does Interlock roofing help with insurance?
In many regions, insurers offer premium discounts for UL 2218 Class 4 rated roofing because it dramatically reduces hail claims. Check with your insurance provider — benefits vary by location and policy.
Will hail dent aluminum roofing?
Interlock’s heavy-gauge aluminum profiles with textured finishes are engineered to resist denting from typical hail. Customers report golf-ball-sized hail leaving no dents or blemishes — and the Class 4 rating backs that up.
