Use a lifting plate that is 12”x12”x3/16” with a 4x5 grid of holes to attach screws through and into the OSB skin of the panels. (The plate should have a “U” welded to it to fasten the lifting device to.) A minimum of two plates should be used to lift each panel.
Determine the center of each panel. Depending on the pitch of the roof, drill your hole for the picking eye, or place the center of the two lifting plates, 3” from the center of the panel toward the ridge end for every pitch change after 4:12. For example: On a 7:12 roof, the lifting hole will be 9” from the panel center. This will allow the panel to arrive on the ridge at almost the proper pitch, which will help the panel installation. If you use the picking eye, be sure to fill the hole with expanding foam sealant prior to installing roofing felt. (If the roof panel has installed lumber, the placement of the lifting eye or plates may need to be adjusted.)
During the install, it is recommended that you alternate the placement of the panels on either side of the ridge beam. Start with two panels on one side of the ridge, then four on the other side. To help prevent the ridge beam from bowing, alternate this sequence for the balance of the roof. To make placement of adjacent panels easier, do not fasten the last screw tightly at the ridge or eave of the leading panel edge, as it It may become difficult to place the next panel due to compression from the last screw.
In some wall/roof connections, as shown on the previous page, the electrician can run the wires in the void created by the beveled block. Once the wires are in place, spray expanding foam in the void or use an EPS wedge infill.
