    1. INSTALLATION OF STARTER SHINGLES

      1. General:

        1. Install in accordance with GAF®'s instructions and local building codes. When local codes and application instructions are in conflict, the more stringent requirements shall take precedence.

        2. Refer to application instructions for the selected starter strip shingles.

      2. Placement and Nailing:

        1. For maximum wind resistance along rakes & eaves, install any GAF® starter strip containing sealant or cement shingles to underlayment and each other in a 4" (102mm) width of asphalt plastic roof cement.

        2. Place starter strip shingles 1/4" – 3/4" (6 – 19mm) over eave and rake edges to provide drip edge.

        3. Nail approximately 1-1/2" – 3" (38 – 76mm) above the butt edge of the shingle.

        4. Rake starter course should overlap eave edge starter strip at least 3" (76mm).

    2. INSTALLATION OF SHINGLES

      1. General:

        1. Install in accordance with GAF®'s instructions and local building codes. When local codes and application instructions are in conflict, the more stringent requirements shall take precedence.

        2. Minimize breakage of shingles by avoiding dropping bundles on edge, by separating shingles carefully (not by "breaking" over ridge or bundles), and by taking extra precautions in temperatures below 40 degrees F (4 degrees C).

        3. Handle carefully in hot weather to avoid scuffing the surfacing, or damaging the shingle edges.

      2. Placement and Nailing:

***Tear-Off or New Construction***

        1. Secure with 4, 5, or 6 nails per shingle per GAF®’s application instructions or local codes.

        2. Placement of nails varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.

        3. Nails must be driven flush with the shingle surface. Do not overdrive or under drive the nails.

        4. Shingle offset varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.

      1. Placement and Nailing:

***Recover***

        1. Beginning with the starter strip, trim shingles so that they “nest” within the shingle located beneath it. This procedure will yield a first course that is typically 3 inch (76mm) to 4 inch (102mm) rather than a fully exposed shingle.

        2. Laterally, offset the new shingles from the existing keyways, to avoid waves or depressions caused by excessive dips in the roofing materials.

        3. Using the bottom of the tab on existing shingles, align subsequent courses.

        4. *Note: DO NOT install standard sized shingles (5inch exposure) over metric (5 5/8 inch exposure) shingles, as it will overexpose the shingles and reveal the nails. Use standard alignment methods to assure proper shingle placement.

        5. Secure with 4, 5, or 6 nails per shingle per GAF®’s instructions or local codes.

        6. Placement of nails varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.

        7. Nails must be driven flush with the shingle surface. Do not overdrive or under drive the nails.

        8. Shingle offset varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.
