MR-24® Roof System

The MR-24® roof system is specified twice as often as any other standing seam roof system—with over two billion square feet installed since 1969 and lifecycles of 40 years have been achieved. It is the standard by which other metal roof systems are judged.

The MR-24 roof acts like a single steel membrane to protect your entire building with exclusive features that ensure weathertightness—factory punching, a 360 degree Pittsburgh double-lock standing seam and staggered endlaps. All accessories and integrated panels are also engineered for an exact fit.

The MR-24 system offers complete design flexibility and can be used in conventional steel structures using:

  • Z-purlins
  • Truss purlins
  • Bar joists
  • Retrofit subsystems

Available with the best roof warranty in the industry—25 years against weathertightness as well as perforation—the MR-24 roof system is the best insurance for the long life of your building.
