Four key sections: Test Apparatus, Test Specimen, Loading Procedure and Test Report MCA establishes a new metal flashing test standard to strengthen storm-proofing C
most traditional roof systems. However, when a roof failure does occur, research shows that flashing failure can contribute to the event. In response, the MCA launched an initiative to create this new standard. "Hundreds of roof failures due to high winds have been in- vestigated," said Bob LeClare , director of perimeter edge metal business for ATAS In- ternational . "These include hurricanes Charley, Ivan, Ka- trina, Ike and Irma. In every one of the these reports you will find that metal flashing failures are cited as a leading cause of roofing system failures." Flashings are fabricated sheets of aluminum, copper, steel, zinc or other metals used to help weatherproof a building. For low slope roofing, flashings are at the perimeter of the roof; on steep slope roofs they're at eaves, gables, hips, and ridges. "The locations of these flash- ings are also where the highest wind uplift pressures occur, so it's critical that they're de- signed, manufactured and installed to resist those higher wind pressures," said LeClare. The standard consists of four key sections: Test Apparatus, Test Specimen, Loading Proce- dure and Test Report. MCAwill be proposing that testing metal roof flashings per this standard be included in the next version of the International Building Code (IBC) in 2024. Meanwhile, the standard is available to specifiers and manufacturers of metal roof systems to assure proper performance of the edge flashings with metal roof sys- tems and assemblies.

HICAGO, IL — The Metal Construction Association (MCA) has released a new standard for testing the performance of metal flashings used with metal roofing systems. The standard, ANSI/MCA FTS-1- 2019, “Test Method for Wind Load Resistance of Flashings Used withMetal Roof Systems” is available now on MCA’s website. Metal roofing systems of all types have proven to perform well in high winds. Properly detailed and installed, metal roofing typically withstands the forces of nature better than
