55% Al/Zn coated steel (Galvalume™) standing seam was introduced in the 70's and now has a 35-year track record in service. How is it performing? What about the sealants, fasteners and ancillaries? Based upon empirical data, what is the projected service life of such a system when installed by today's "best practices"? An industry effort involving field inspections of aged roofs answers these questions. The short answer is 50-70 years. The details are in the course.

Learning Objectives:

• Identify the real expected service life of this roof type
• Determine the type of capital repair that may be necessary and the expected cost
• Determine what punctuates "service life" and how that is determined
• Define what constitutes "best practice" with respect to various aspects of these roof systems and their ancillaries

Target Audience:

• Commercial Contractor
• Metal Contractor
• Superintendent-Foreman
• Architect/Designer/Consultant
• Manufacturer-Supplier
• Sales & Estimating
• Owner/CEO/General Manager
