The Midwest is known for its ever-changing weather—calm blue skies can suddenly give way to roaring winds, heavy rainfall, and even tornadoes. For commercial buildings in this region, it’s not just about having a roof overhead; it’s about having a structure that can stand strong when severe storms strike. That’s where Butler building systems come in. Thanks to advanced engineering, rigorous testing, and innovative design, Butler’s roofs and structural components are built to handle the toughest conditions the Midwest can throw at them.

Engineered for Extreme Conditions

Butler building systems are carefully designed to provide strength and durability, even when facing intense wind gusts or sudden temperature swings. At the heart of this performance is the MR-24 roof system. This metal roof is engineered to resist wind uplift, which is the upward pressure created when strong winds race across a building’s surface. In the Midwest, gusts can easily surpass 100 miles per hour in severe storms, making proper wind-uplift resistance a must.

Proven Through Rigorous Testing

Butler’s MR-24 roof system doesn’t just claim strength—it proves it through extensive testing that follows strict industry standards. For example, Underwriters Laboratories (UL) assigns wind-uplift ratings that show how well a roof can handle different levels of pressure. The MR-24 roof system easily meets UL Class 90 standards. Class 90 means the roof can handle uplift pressures of around 105 pounds per square foot, similar to what you’d find in roughly 200-mile-per-hour wind conditions. This rating isn’t something just handed out; it’s earned through controlled tests where a section of the roof is subjected to increasing pressure until its limits are found.

Staying Watertight and Airtight Under Stress

One of the standout features of the MR-24 roof is its ability to maintain a tight, secure seal, even as it bends slightly under intense pressures. Rather than failing at the seams, the roof’s unique design and seaming process help keep water and air from passing through. In real-world conditions—whether it’s a thunderstorm or the lingering aftermath of a tornado—this ensures that your building remains dry and stable. Many other roofs might struggle when tested to these extremes, but Butler’s design keeps the building envelope intact, protecting your interior and everything inside.

Tailored for the Midwest and Beyond


What makes Butler building systems, and the MR-24 roof in particular, so valuable for Midwest businesses is that they’re not over-engineered “just because.” These roofs are created with local conditions in mind. The same wind uplift tests that show a roof can stand up to near-hurricane-level winds ensure it can handle those unpredictable summer storms or sudden gusts that define the region’s climate.

When you choose a Butler building system from MAR Building Solutions, you’re not just getting a structure—you’re investing in peace of mind. You’re choosing proven engineering that’s designed to handle extreme conditions. From soaring winds to drenching rains, Butler building systems have been tested, proven, and trusted to protect what matters most in the heartland and beyond.
