Skyline Roofing Panel Installation. Place an alignment line along the gable end where the first panel will be installed, one quarter inch from the gable edge and square with the eve line. Align the female edge of the first panel with the alignment line. Allow the panel to overhang the eve one inch. Check the uphill alignment of the panel. Fasten the gable end to the roof using number 14 by one inch wood fasteners at specified spacing per installation guide. Fasten along the male edge fastening flange using number eight by one inch modified truss head wood screws at specified spacing per installation guide. Fasten the panels along the eve with three evenly spaced number 14 by one inch wood fasteners located along a straight line parallel to the eve and three inches up from the end of the panel. Align the second panel female edge with the first panel male edge. Make sure the panels are flush with each other at the eve edge. Snap the panels together at the seam with light foot pressure. Work the seam together from the eve end towards the ridge. Do not work the seam both ends towards the middle. After locking the panel seam, fasten the panel to the roof utilizing the fastening flange along the male edge with number eight by one inch modified truss head wood screws at specified spacing. Apply consecutive panels.

Speaker 1:
Ridge Flashing. Locate the panels down from the ridge per the installation guide. Apply butyl mastic tape and install the polyethylene closure. Apply butyl mastic tape over the top of the closure. Fasten Z closures along the ridge using number eight by one inch modified truss head wood screws at 12 inches on center. The installed panel length should allow space for Z closure and a minimum of three-eighths inch gap. After all gable trims are in place, fasten the ridge flashing to the Z using number 12 by three-quarter inch stitch screws adjacent to each rib. For vented ridges, the substrate should be held back two inches from each side. Locate the panels down from the ridge per the installation guide. Turn up the panel and caulk at the sides near the ribs. For increased weather tightness, add neoprene closures below the panel turn up. Attach perforated Z closures at the top edge of the plywood and parallel to the ridge using number eight by one inch modified truss head wood screws at 12 inches on center. The installed panel length should allow space for Z closure and a minimum of three-eighths inch gap. After gable trims are in place, fasten the vented ridge to the Z closure using number 12 by three-quarter inch stitch screws adjacent to the panel ribs. Caulk, lap, and rivet sequential flashings as previously demonstrated with the eve.

Speaker 1:
Gable Flashing. Snip and fold the gable at the eve, as shown, to close the end and secure with a rivet, as demonstrated in the installation guide. Place butyl mastic tape along the gable flashing's flange, as shown. Install the gable flashing by placing it firmly over the rib and pre-drilling holes 24 inches on center, and then fasten using wood screws. Lap gable flashing by applying sealant and hooking the hems, as previously demonstrated with the eve flashing hem. For the end gable flashing, trim the panel one half inch past the roof edge. Fold one inch of the panel up 90 degrees, leaving a half inch between the panel and the roof edge. Prepare the end gable flashing in the same manner as the start gable flashing. Place butyl mastic tape along the gable flashing's flange, as shown, and install the gable flashing by placing it firmly over the rib and pre-drilling holes 24 inches on center, and fastening using wood screws. 

Speaker 1:
Miter cut the flashing at the peak to join each side of the ridge. Remove a pie shaped piece from the outside facing edge, as demonstrated in the installation guide, and notch the down turned leg, as shown. Fold the tab behind the edge and secure it with two rivets. Remove a portion of the gable flashing to allow continuous Z closure. To close the end of the ridge flashing, remove the highlighted material, cut at the dotted lines, and fold the remaining sections. Rivet and trim to close the end of the ridge flashing. Fasten the ridge flashing to a Z closure using number 12 by three-quarter inch stitch screws adjacent to each rib. 

Speaker 1:
Valleys. Prior to installing panels into valleys, place a second layer of 36 inch roof felt in the valley center line starting at the low end. Remove the highlighted portion and place the valley flashing so that it overhangs the eves one inch. Bend the two protruding sections down to meet the eve and fill the open end with sealant. Caulk and overlap the subsequent valley flashings by a minimum of eight inches. Parallel to the valley, place two rows of butyl mastic tape spaced as shown. Field cut the panels holding a minimum of four inch back from the valley, as shown. Wider valley flashings and larger panel setbacks maybe required in certain climates. Fasten the panels to the roof using four number 14 by one inch wood screws evenly spaced eight inches up from the valley center line so they align with the second row of tape sealant. 

Speaker 1:
Peak Flashing. Apply butyl mastic tape and install the polyethylene closure. Apply butyl mastic tape over the top of the closure. Attach the solid Z closure at the top of the panel parallel to the peak. The installed panel length should allow space for Z closure and a minimum of three-eighths inch gap. Fasten the peak flashing to the Z using number 12 by three-quarter inch stitch screws adjacent to each panel rib. Caulk, lap and rivet sequential flashings.

Speaker 1:
Sidewall Flashings. The roof should be installed prior to the siding. Trim the panel adjacent to the wall and turn up one inch of the end. Locate the panel one half inch from the wall. Trim, bend and close the end of the Sidewall flashing per the installation guide. Place butyl mastic tape along the Sidewall flashing's flange, as shown. Install the sidewall flashing by placing it firmly on the roof and fasten using number 14 by one inch wood screws 24 inches on center into pre-drilled holes in the roofing panels. Fasten the end wall flashing to the wall with pancake head wood screws, or roofing nails, at 24 inches on center. 

Speaker 1:
End Wall Flashing. Apply butyl mastic tape and install the polyethylene closure. Apply butyl mastic tape over the top of the closure.
