STANDING SEAM METAL
Standing Seam Metal. The Best Lifecycle Cost in Commercial Roofing.
40 to 70 year service life with maintenance. Concealed fasteners eliminate the primary failure mode of exposed-fastener metal. AOD installs structural and architectural standing seam for federal installations and commercial applications.

Panel Systems
Structural: self-supporting for open-purlin applications. Architectural: over solid decking for retrofit. 12"-18" widths. Steel
(Galvalume or painted), aluminum, Cor-Ten. Snap-lock and mechanically-seamed options.
Lifecycle Cost
40-70yr service life = lowest lifecycle cost per year of any commercial system. AFCEC and Army IMCOM specify standing seam on new construction for this reason.
RAMP™ Notes
Standing seam maintenance focuses on panel sealant at penetrations, gutter function, and snow guard condition. These buildings typically score 1-2 on AOD's risk scale when properly installed.
Applications
Air Force, Army, Navy new construction. Institutional and high-visibility facilities. Municipal buildings, courthouses, commercial industrial.
