Certain Metal Roof Systems Have a Service Life of at Least 60 Years

The Athena Sustainable Materials Institute (ASMI) has accepted a recent report published by the Metal Construction Association (MCA) that verifies certain metal roof systems can have a service life of at least 60 years. The service life report served as the technical substantiation required for Athena to change the useful service life of this type of roofing product to 60 years, which can be longer than the buildings they cover.

“We are honored that our service life study for metal roofing met Athena’s high standards and will now be used in whole building life cycle assessments for buildings throughout the country,” says Scott Kriner, MCA’s technical director

Athena’s software allows for whole building LCA assessment, taking into account all materials, systems, assemblies and components used in a given type of building. The Metal Roof Service Life report, which was sponsored by MCA and the ZAC Association, studied the service life of unpainted 55 percent Al-Zn low-slope standing-seam metal roofing in a wide range of different environments across the U.S.
