Brief installation guide
Step 1
Make sure panel is free of dust and debris. If not precut, cut 2” slot at ridge. Measure and mark where the ridge cap will sit on the panel.
Step 2
Start from the end of the ridge, rolling out Flex-O-Vent along the length of the ridge (both sides), making sure the vent sits “up-slope” from the edge of the ridge cap.
Step 3
Apply ridge cap, compressing material between the ridge cap and major rip. Fasten at the major rib using a screw gun set to at least 2700 rpm.
