• Metal Frame Carport or Shed Not Incorporating Eave Overhang Or Soffit Box When a carport or shed does not incorporate a Soffit Box, the roof panels simply follow the contour of the structures frame and wrap around the eave location. This produces a unique panel installation which begins at the ridge location rather than the eave. All flashing and trim that fit over the rafters of the structure should be in place before installing the panels. Do not fasten these flashings through the top of the rafter due to interference with the panels. Limit 26 gauge GrandBeam panels to no greater than 27'6" for ease of handling. Limit 29 gauge embossed GrandBeam panels to 18'6" for ease of handling. NOTE: 29 gauge embossed GrandBeam is for siding purposes only, not roofing. 1. Begin panel placement approximately 3" to 3 1 /2" down slope from the center of the ridge. After the panel has been determined to be square, install #12- 14x1" HWH SDST screw with sealing washer through each flat of the panel and into every rafter location. The correct location for the fastener is in the flat part of the panel, directly before the rise of the panel rib (Detail A). Gable ends receive two fasteners in the flat (see fastener location detail). Do not place fasteners in the lower flat (at first rib) of the panel at this time. If more than one panel is needed per course, complete the course using the standard GrandBeam sidelap detail. Install panels so sidelaps are staggered from those of the previous course. 2. Install the next panel or course making sure that the correct GrandBeam panel endlap is being achieved. The lower portion of the GrandBeam panel will have to be lifted slightly, giving the panel being installed, the ability to fit under the lower rib of the previously installed panel. The bottom hem of the previously installed panel should fall over the anti - siphon channel of the panel being installed (Detail A). The 3
