Hip/Ridge Flashing
Procedures
• Caulk the bottom and sides of the polyethylene
closure. Set the closure as shown above and caulk
the top. The closure is optional if the panel is turned
up and caulked at the sides near the rib.
• Fasten the ridge cap using stitch screw at each rib
or 8" o.c. for corrugated.
• Close the ends of the universal ridge cap by cutting
and folding material at each end. Fasten with rivets.
(see page 10)
• Caulk, lap and rivet sequential ridge flashings.
