1.1 This specification covers the design, construction, and weatherability of structural standing seam steel roof panel systems that can resist all superimposed design loads without the benefit of a supporting deck or sheathing. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers. Many of these systems are used on low-sloped roofs when installed in accordance with the manufacturer's recommendations.
1.2 The objective is to provide for the performance of the standing seam steel roof panel system as defined in 1.1 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 periodic maintenance of equipment by the owner.
1.3 In addition to structural, 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 designer's checklist.
1.4 The specification is not intended to exclude products or systems not covered by the referenced documents.
