Specifications include, but are not limited to: MECHANICALLY FASTENED MEMBRANE ROOFING INSTALLATION A. Mechanically fasten membrane roofing over area to receive roofing and install according to roofing system manufacturer's written instructions. 1. Install perimeter/half sheets across the entire roof surface. 2. Strap the roof vertically. 3. For in-splice attachment, install membranes roofing with long dimension perpendicular to steel roof deck flutes. B. Start installation of membrane roofing in presence of roofing system manufacturer's technical personnel. C. Accurately align membrane roofing and maintain uniform side and end laps of minimum dimensions required by manufacturer. Stagger end laps. D. Mechanically fasten or adhere membrane roofing securely at terminations, penetrations, and perimeter of roofing. E. Apply membrane roofing with side laps shingled with slope of roof deck where possible. F. In-Seam Attachment: Secure one edge of membrane sheet using fastening plates or metal battens centered within membrane seam and mechanically fasten membrane sheet to roof deck. G. Metal Stress Plate Installation: 1. Install fasteners every 6" along the seams. 2. Install plates in straight rows in the specified number and spacing to achieve the required wind uplift resistance in the main field, edges and corners of the roof. 3. Install plates and separation pads using fasteners that comply with the specified applicable building code wind uplift rating and the fastener and membrane manufacturer's requirements. Ensure that all fasteners are properly driven normal to the surface of the sub-structure. Do not over-drive fasteners; plates that are recessed into and/or not flush with the surface of the insulation are not acceptable.
