Examine metal roof panel installation substrate with Installer present. Inspect for erection tolerances and other conditions that would adversely affect installation of metal roof panels. B. Roof Substrate: Confirm that wall substrate is within tolerances acceptable to metal roof panel system manufacturer. 1. Maximum deviations acceptable: a. b. 1/4 inch in 20 feet (6 mm in 6.1 m) out of plane 1/2 inch (12.7 mm) over entire roof C. Framing: Inspect framing that will support metal roof panel system to determine if support components are installed as indicated on approved shop drawings. Confirm presence of acceptable framing members at recommended spacing to match installation requirements of metal roof panels. D. Advise G.C., in writing, of out-of-tolerance work and other deficient conditions prior to proceeding with metal wall panel system installation. E. Correct out of tolerance work and other deficient conditions prior to proceeding with panel installation. 3.2 INSTALLATION A. General: Install metal roof panel system in accordance with approved shop drawings and manufacturer's recommendations. Install metal roof panels in orientation, sizes, and locations indicated. Install metal roof panels in one piece lengths from the ridge to eave unless otherwise indicated on approved shop drawings. Anchor panels and other components securely in place. Provide for thermal and structural movement. B. Attach panels to metal framing using recommended screws, fasteners, sealants, and adhesives indicated on approved shop drawings. 1. 2. 3. CENTRIA Fasten metal roof panels to supports with exposed fasteners at location, spacing recommended by manufacturer, and with fasteners recommended by manufacturer. Anchor to supports with self-tapping fasteners approved by manufacturer. Provide weatherproof escutcheons for pipe and conduit penetrating roof. Dissimilar Materials: Where elements of metal roof panels installation will come into contact with dissimilar materials, treat faces and edges in contact with dissimilar materials as recommended by manufacturer. 07 41 13 Page 15 of 16 Metal Roof Panels 3.3 ACCESSORY INSTALLATION A. General: Install metal roof panel accessories with positive anchorage to building and weather tight mounting and provide for thermal expansion. Coordinate installation with flashings and other components. 1. 2. 3. 4. 3.4 Install related flashings and sheet metal trim per requirements of Division 07 Section "Sheet Metal Flashing and Trim."
