Atlas Roofing
11. HIP AND RIDGE
To prevent cracking in cold climates when applying to hips and ridges, shingles must be sufficiently
warm and flexible. Apply Atlas Pro-Cut® Hip & Ridge shingles with a 5 5/8" exposure, beginning at
the bottom of the hip or from the end of the ridge in the direction opposite of prevailing winds. Use
two 1-1/2" long nails per shingle, with one nail on each side, 6 1/4" back from the exposed end and
1" up from the edge so succeeding shingles conceal nail heads. Trim final shingle to fit and set in
plastic cement. Hip and Ridge shingles may also be made from the GlassMaster® 30 3-tab shingle.
Cut the strip in thirds. Taper the top portion of each slightly so that it is narrower than the exposed
portion. See Diagram #8.
