Handling Hips
For hips, sheets from either side must meet to support hip
cover. To cover the hip, use an ONDURA® Ridge Cap.
Framing should be in place beneath and near enough to the
upper ends of the screws securing the hip cover.
Snap chalk lines on each side of the hip to mark the area of the
hip cover. See diagrams.
Closure Strips:
Cut one hip section or two corrugations from the ONDURA®
closure strip. Attach to the top side of the ONDURA® sheet with
rubberized elastomeric flashing cement/caulk. Install with 7-
inch end laps.
Ondulair Slim (right):
Seal top with Ondlair Slim flashing. Then install the hip cover with
7-inch end laps over the flashing.
Valley Flashings
For valleys, install a minimum 18-inch wide metal valley
flashing. Cut sheets at an angle to fit the valley; then turn over,
and on the undersides along the valley edge, caulk two
corrugations of the ONDURA® solid closure strip, and place into
the corrugation. Then put a ½-inch bead of caulking on the flat
side of the solid closure strips and along the corrugation of the
sheet between the solid closure strips. Turn sheets right side
up, carefully lay in place so caulked closures seat on flashing,
and fastener in place at least 12 inches up from the center of
valley without puncturing the metal flashing.
2 to 5 inches from valley
Slope Changes
Flashing width should increase as slope differences increase or
whenever water buildup on the lower slope can be substantial.
