Hip & Ridge Detail
Valley Detail
Hip and ridge applications are handled in
the same manner.
1. Install roof panels to meet at hip or
ridge. (Depending on roof geometry
and run of roof, the top panel may have
to be cut along the length of panel.)
2. Lay a 6” strip of closure tape across
panels at hip/ridge line.
3. Lay cap on roof and secure the cap
with clips and screws, (2) per piece.
Ridge caps can accommodate standard
ridge venting products. Refer to venting
manufacturer's instructions and local
building code requirements.
Note: For hip applications, fasten the caps
with clips at the high point on the shingle
in order to avoid dimpling, and make sure
the clip and screw penetrates the cap
through the closure into the solid
substrate.
1. Install self-adhered roofing underlayment
18” up both sides of the valley line.
2. Install the valley pan and clip fasten
through the substrate at 24” o.c.
3. Measure required panel to length to come
within 3” of center of valley.
4. Cut and fold panel on diagonal to create a
solid end and fasten with stainless steel color
matched pop rivet to hold in place.
5. Lay shingles onto the valley pan
maintaining at least 3” clearance from the
valley’s center and fasten with clips outside
the valley pan.
