Third Course: Repeat first course with a full shingle to start at the rake edge.
Fourth Course: Remove 1-1/2 tabs from the left end of a shingle and apply it over and above the
third course shingle, flush with the left edge of the rake leaving 8 1/2" exposure.
10.) STEEP SLOPE AND MANSARD APPLICATIONS
Immediately upon application to slopes exceeding 45 degrees (or 12” in 12” slope), 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. (See DIAGRAM #3 for proper fastening instructions.)
11.) 130 MPH HIGH WIND APPLICATION
To achieve the 130 MPH Wind Warranty provision the following products are REQUIRED in the 130
MPH roof covering assembly: PRO-CUT® STARTER STRIP, ATLAS PRO-CUT® HIP AND RIDGE
SHINGLES, and one or more of these ATLAS UNDERLAYMENTS - Min. ATLAS #30 ASTM D 4869,
GORILLA GUARD®, SUMMIT® SYNTHETIC, and/or WEATHERMASTER® Granular Underlayment, and
the 6 NAIL FASTENING METHOD. If the above described method is not followed, the shingle will be
covered by a 110 mph Wind Warranty. See ATLAS SIGNATURE SELECT® LIMITED WARRANTY FOR
HIGH WIND WARRANTY PROVISION. (See DIAGRAM #3 for proper fastening instructions.)
12.) HIP AND RIDGE
(NOTE: Atlas Pro-Cut® Hip & Ridge featuring Scotchgardf 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. Separate the Pro-Cut®
Hip & Ridge shingle into three equal pieces along the perforated lines provided. 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. (See special requirement section
