Service Life Assessment of Low-Slope Unpainted 55% Al-Zn Alloy Coated Steel Standing Seam Metal Roof Systems

This report documents and summarizes the work conducted to determine with reasonable certainty the roof service life that can be expected of a “like-in-kind”, low-slope 55% Al-Zn alloy-coated steel Standing Seam Roof (SSR) system when installed today in a like environment using best practices. It incorporates the results of multiple field inspections, independent laboratory analyses of metallic corrosion of roof panels, components and sealants, and includes assessment of all integral ancillary components that impact the end of roof service life.

• Insulated Metal Panels and NFPA 285

IMP panels are required to be tested in accordance with NFPA 285 and specific IMPs have been tested and meet the conditions of acceptance of NFPA 285. Since every variation of a wall system cannot be tested,if the “basic” IMP panel system meets NFPA 285, minor variations in items can be allowed without retesting or an analysis.

• Oil Canning in Metal Roof and Metal Wall Systems

Many uncontrollable factors contribute to oil-canning and no panel manufacturer, fabricator, or installer can assure the total prevention of oil canning on any given project. With careful attention to the production, material selection, panel design, and installation practice, the tendency for oil canning can be minimized.

• Metal Roof and Wall Panel Components in Contact with Preservative-Treated Lumber

The use of copper-containing preservative-treated lumber in direct contact with certain metal products could lead to accelerated corrosion and affect the long-term integrity and performance of a metal roof or wall system. The most effective way to avoid corrosion is to ensure that the treated lumber used is either manufactured using the newer metal-free preservatives, micronized copper treatment or that there is a separation between the metal roof or wall panel and the preservative treated wood with some type of barrier material.
