Installation Instructions

10.) STEEP SLOPE AND MANSARD APPLICATIONS
Immediately upon application to slopes exceeding 60°(or 21:12), apply six (6) quarter size spots of asphalt
plastic cement under each shingle. All six spots are to be approximately 1" up from the bottom edge of the
shingle and spaced equally across the shingle with the two outer spots located 1" in from each outer edge. The
cement should not be exposed when shingles are pressed into position. Excessive
use of roofing cement can cause shingles to blister.
CAUTION: STEEP SLOPE AND MANSARD APPLICATIONS BOTH REQUIRE 6 NAILS EVENLY
SPACED ALONG THE LENGTH OF EACH SHINGLE.
11.) HIP AND RIDGE
(NOTE: Atlas Pro- Cut® Hip & Ridge featuring Scotchgard™ or Atlas Pro- Cut® High Profile Hip & Ridge
featuring Scotchgard™ must be used as hip and ridge for the roof to qualify for Scotchgard™ Limited Warranty
Coverage.) 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 nails per shingle,
as specified under Section 8– Fastening, with one nail on each side, 6" 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. See
Diagram #6. When installing ridge vents follow vent manufacturer’s instructions.
