Hail can be one of the most damaging weather events for buildings. In states like Colorado, Nebraska, Oklahoma, and Texas, large hail is not only common—it’s costly. That’s why Johns Manville conducts severe hail testing in-house to ensure our roofing systems are built to endure.
In our hail testing lab, JM engineers simulate the real-world impact of hailstones striking a roof. By replicating these conditions, we can measure how different systems perform and continuously improve our products for strength and resilience.
This rigorous approach helps us deliver more than just durability. The longer a roof lasts, the more sustainable it becomes:
- Less roofing material ends up in landfills
- Fewer replacement projects mean fewer trucks on the road
- Building owners save time, money, and resources over the long term
Watch how we test our roofing products, ensuring they can stand up to storms and contribute to a more sustainable built environment.

A roof that lasts longer doesn’t just save money—it’s better for the planet. At JM, our severe hail testing ensures longer-lasting roofs, reducing the need for replacement and diverting waste to landfills. Resilience and sustainability go hand in hand. In regions like Colorado, Nebraska, Oklahoma, and Texas, hailstorms are a growing challenge. But they’re also an opportunity to innovate smarter, longer-lasting solutions. We simulate severe hail conditions in the lab—replicating the impact of large hailstones that can devastate unprepared buildings. By testing our roofing systems under these harsh conditions, we help ensure they stand the test of time. Why does that matter for sustainability? Because the longer a roof lasts, the less often it needs replacing. That means: · Less material ending up in landfills · Fewer trucks on the road hauling waste or delivering new products · Lower environmental impact across the supply chain It’s about protecting buildings today—and protecting the planet for tomorrow. #BuildingABetterTomorrow #JohnsManville #Sustainability #BuiltToProtect #Roofing
