About this file

This is a technical specification document for steel standing seam roofing systems at Tinker Air Force Base, Oklahoma, dated April 2019.

The specification requires a complete standing seam metal roof system (SSMRS) from a single manufacturer with a minimum five-year history manufacturing similar systems and involvement in at least five comparable projects. Roofing panels must be continuous lengths with no joints except at specified locations, fabricated from zinc-coated steel (ASTM A653/A653M, G90) or aluminum-zinc alloy-coated steel (ASTM A792/A792M, AZ55) with minimum thickness of 0.023 inch (24 gage), or 0.030 inch (22 gage) if mid-field experiences wind uplift of 60 psf or greater. Steel roofing materials must contain minimum 30 percent recycled content and be Energy Star labeled with initial solar reflectance greater than or equal to 0.25. Panels require factory-applied thermally cured coatings with 70 percent resin polyvinylidene fluoride exterior finish at 0.2 mil dry film thickness minimum. The system must resist wind loads based on 120 mph basic wind speed with design uplift factors of 3.0 for single fasteners and 2.25 for multiple fasteners per connection, support 20 psf minimum live load, accommodate thermal movement across 10°F to 140°F temperature range, and limit deflection to L/180 of span. Installation requires manufacturer's technical representative field inspections during first 20 squares and substantial completion, with a manufacturer's 20-year no-dollar-limit materials and workmanship warranty plus contractor two-year installation warranty. All components including clips, closures, fasteners, sealants, and accessories must be from the same manufacturer system. Submittals require government approval for shop drawings, product data, design calculations, field inspection reports, and manufacturer certifications.
