This specification covers the design, construction, and weatherability of structural standing seam aluminum roof panel systems. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers. Structural panels shall be designed in accordance with the required specifications for aluminum structures and in accordance with sound engineering methods and practices. The static load capacity and uplift index shall be tested to meet the requirements prescribed. Connections of panels to structural members shall be made with concealed panel clips compatible with the panel design. A fixing line is required to anchor roof panels in order to maintain end alignment and to resist in-plane gravity and thermal force components. Panel-to-panel sidelap connections and endlaps shall be weathertight. Panels of maximum practicable lengths shall be used to minimize endlaps.

1.1 This specification covers the design, construction, and weatherability of structural standing seam aluminum roof panel systems. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers.

Note 1—These systems are used on both low-slope and steep-slope roof applications. They also are used with or without an underlying deck or sheathing.

1.2 The objective of this specification is to provide for the overall performance of the structural standing seam aluminum roof panel system as defined in 3.2.6 during its service life in order to provide weather protection, carry the specified design loads, and allow proper access over the roof surface in order to provide for periodic maintenance of the equipment by the building owner.

1.3 In addition to structural characteristics, the specifier shall evaluate other characteristics beyond the scope of this specification that affect the final choice of roof construction. These include, but are not limited to, functional, legal, insurance, and economic considerations. See Appendix X1 for the specifier's checklist.

1.4 This specification is not intended to exclude products or systems not covered by the referenced documents.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.6 The text of this specification contains notes and footnotes that provide explanatory information and are not requirements of this specification.
