Procedures
• Plywood should be held back 2" from each side of the
ridge.
• Attach the screen at each panel rib sandwiching the top
closure in place. Ensure screen is pulled tight to avoid
sagging.
• Fasten the vented ridge using stitch screw at each rib
or 8" o.c. for corrugated.
• Caulk, lap and rivet sequential flashings.
(see page 44).
• Close the ends of the ridge cap by cutting and folding
material at each end. Fasten with rivets and caulking
joints. (see page 12).
• Slopes greater than 6:12 may require special
ridge dimensions.

Note: The gable flashing must be installed prior to
installation of the ridge (see page 18).
The screening shown creates a barrier for insects and
birds while allowing for ventilation.
For snow and heavy rain environments, please inquire
about optional Vented Ridge details.
