STORAGE AND HANDLING

Prior to installation, store painted, galvalume and galvanized Rib Panels only in a dry place. Do not store outdoors, nor in any indoor area subject to moisture. Stand panels on end and fanned out at the bottom to provide air circulation, or stack flat in piles on blocks or racks to protect bottom panels from ground moisture. In handling all Rib Panels, lift up and do not slide panels when unstacking or the finish coating may be damaged.

ROOFING INSTALLATION

Slope: Minimum roof slope for Rib Panel is 3 inches rise per foot. Apply sealant at side and end laps for less slope.

Start installing roofing vertically at edge away from prevailing wind. Rib Panel with side lap drain feature may be started from either right or left edge.

IMPORTANT: First roofing panel must be plumb to assure straight alignment of entire row of panels. Tip: stretch chalklines between nails driven into ridge and end of each edge rafter. These lines serve as guidelines to align panels. If roof requires more

 

than one horizontal row of panels, follow these procedures: Temporarily fasten (i.e., at two points – not at ends – along middle main ribs) panel No. 1 in lower corner. Install panel No. 2 above and end-lapping over No. 1. Align both panels with chalkline. Install panel No. 3 next to No. 1, side-lapping over drain feature. Install panel No. 4 above No. 3, side-lapping over No. 2 and end-lapping over No. 3 (see illustration). Check alignment at ridge and cave again. Temporarily fasten all panels; permanently fasten when all panels are in line.

IMPORTANT: Do not temporarily or permanently fasten drain feature rib of any panel until it is side-lapped by adjacent panel.
