The Standing Seam Roof That Never Stands Still

Butler MR‑24® Standing Seam Roof Panels feature ribs spaced 24 inches on center, creating a clean, streamlined appearance while delivering exceptional structural strength. Available in both 22‑ and 24‑gauge steel, these panels let you balance durability, performance, and budget for any Butler building project. Each MR‑24 panel includes a factory‑applied sealant groove for superior weathertightness, ensuring long‑term protection and reliable performance in demanding environments.

The MR‑24® Roof System supports a wide range of rigid and blanket insulation options to boost energy efficiency and reduce utility costs. One of its biggest advantages is the use of high clips, which allow up to R‑32 insulation to be installed over the purlins—saving labor and improving thermal performance. Optional thermal blocks and tall clips increase insulation thickness without restricting panel movement, helping maintain interior comfort and long‑term durability. Paired with Butler‑Cote™ cool‑roof colors, the MR‑24 system delivers a highly efficient roofing solution that keeps buildings cooler and lowers overall energy use.

The Butler MR‑24® Roof System is engineered to withstand the forces of nature, backed by a UL Class 90 wind‑uplift rating and approvals from Factory Mutual and the U.S. Army Corps of Engineers. Every panel splice is positioned directly over structural steel to prevent deflection and seam stress, unlike conventional midair splices. Its concealed, moveable clip anchors the roof securely while allowing full thermal movement, protecting against metal fatigue, fastener pull‑out, and wind‑driven damage for long‑term weathertight performance.

Butler MR-24 Roof Panels are finished in genuine Butler‑Cote™ cool‑roof colors, formulated with premium Kynar 500®/Hylar 5000® fluoropolymer coatings for long‑lasting durability and fade resistance. These high‑performance finishes deliver Solar Reflectance Index (SRI) values up to 91, helping reduce heat absorption, improve building comfort, and lower energy consumption. ENERGY STAR® rated Butler‑Cote™ colors make the VSR II system an energy‑efficient choice for commercial and architectural projects.

The MR‑24® Roof System is engineered to move with the forces of nature. Its concealed roof clip—an essential but unseen component—secures each panel while allowing full thermal expansion and contraction, preventing stress that can cause panel damage, fastener pull‑out, or leaks. Unlike snap‑together seams, MR‑24 uses a heavy‑duty Roof Runner machine to field‑roll the critical 180 degrees into a full 360‑degree Pittsburgh double‑lock seam, creating the tightest, most durable standing‑seam connection available. A factory‑applied sealant inside the seam ensures long‑term weathertightness, even under extreme wind, snow, and temperature swings.

The MR-24 Standing Seam Roof Panel comes in 22 and 24 gauge and can be cut any length up to 40 feet, giving you fast turnaround for both new construction and replacement projects. Panels can be crated and shipped factory‑direct to your jobsite in just a few days, ensuring you get the exact size you need without delays. We also offer the Roof Runner Seamer for rent with certification. Whether you’re starting a new build or replacing an entire wall section, we have you covered with genuine Butler® quality and dependable delivery.
