MR-24: Celebrating 50 Years of Superior Performance

50 years ago, Butler^® revolutionized the building industry with the MR-24^® roof system: the industry’s first and finest standing-seam metal roof system. The MR-24 roof system is specified twice as often as any other standing-seam roof system and has set the standard by which all other systems are judged. In fact, more than 3.2 billion square feet of this roof system has been installed since 1969.

Since its inception, our MR-24 roof has been known for its reliability and excellent return on investment. Its factory-punched panels, movable clips, and Pittsburgh double-locked seam create a weathertight performance that provides dependable protection for years to come.

This system also offers reliable wind protection for areas that need it the most. With the highest UL wind uplift rating (Class 90), our MR-24 roof is U.S. Army Corps-tested, FM Global available, and Miami-Dade County-approved. And with 50 years of making it better, our current MR-24 operates at the highest level of efficiency and results than ever before.

Today’s MR-24 system is durable, flexible, and versatile. It’s suitable for most roof retrofits and re-roofing projects and is virtually maintenance-free. And with steel as its main material, a variety of color options, and the inclusion of our innovative SunLite Strip® daylighting system, it’s more sustainable and energy-efficient than many other options on the market. Tested assemblies, using MR-24, give you the ability to meet the latest energy codes using standard Butler materials to reduce in-place construction costs.

Since 1969, MR-24 roofs have been the go-to choice for Butler Builders throughout North America. Learn more about our innovative and long-lasting MR-24 roof systems today.
