MR-24® Roof System

Leaks and faulty roofs are very costly. A leaky roof will damage products, interrupt work flow and generally disrupt business. When you consider what your time is worth, a building with a leaky roof at any cost will always cost more than a weather-tight structure. CCC believes the MR-24® Roof Sytem from Butler is the best in the metal roof industry.

The Strength of the MR-24

There are two basic types of metal roofs: fasten-through (also known as screw-down roof), and standing seam.

The fasten-through roof is a metal roof that is screwed down to the roof structure using screws as mechanical fasteners. It has a lower cost than standing seam. But it also has the disadvantages of many small screw holes and limited expansion and contraction. More wear on the fasteners’ holes give rain and sun just the opening it needs.

The Butlerib II roof system, Butler‘s own fasten-through system, is the most highly engineered, highest quality fasten-through roof available. It uses slots for the screws to facilitate expansion and contraction. It is the only fasten-through roof that has the option of a weather-tightness warranty.

A standing seam roof is a metal roof that fastens to a structure without holes or penetrations. A standing seam roof acts like a single steel membrane to protect your building.

The Butler MR-24 standing seam roof has many advantages. The greatest advantage is the fact that there are the fewest possible penetrations. The roof is fastened to the structure using a mechanical seaming tool known as a “no-clip seamer.” This tool bends the metal and forms the final shape and connects to the structure without penetrating the roof.

Fewer holes in a roof mean fewer leaks. The MR-24 roof is able to expand and contract a full 2 1/2″ without placing any stress on the structure. This means that the building lasts longer.

To put this in perspective, in CCC‘s market area, a 125’ wide roof will expand and contract 1 5/8″ on a typical summer day! A roof that does not have the engineered protections of the MR-24, will not expand and contract enough or in the right way.

The Butler Guarantee

A Butler MR-24 standing seam roof has the longest lifespan of any roof on the market. There are many documented cases of this roof lasting 30 to 40 years. The next best roof life is rubber membrane with a 10- to 15-year life. There are cases of rubber membrane and asphalt roofs lasting longer than 15 years, but the maintenance costs become very high.

Using a complete system that ensures quality workmanship and a superior product, Butler offers the:

  • Longest life,
  • Lowest life-cycle cost,
  • Lowest maintenance, and

Most trouble-free roof for which an owner could ask.

The Butler MR-24 standing seam roof is truly an excellent product of superior engineering and manufacturing practices. Engineered Protections Are Built Into The Butler MR-24 Roof:

  • Pre-punching. This assures alignment giving straight seams so that roof can expand and contract without structural stress
  • Staggered end lap splices.
  • Endlaps over purlins.
  • Maintained seamers. These seamers cannot be purchased. They are rented and returned to Butler every three months for maintenance and calibration
  • Superior connections. The connection clip between the roof and the building has stainless steel tabs and other engineered high strength parts designed to give the owner a long-term trouble-free, water-tight environment.
