and seal with plastic cement or high quality urethane sealant; nail at the top of the
flange.
2. In the north, and on all roofs between 2/12 and 4/12 (low slopes) install GAF leak

the valley. Lap ends 6 inches (152mm) and seal.
***** FOR OPEN VALLEY ONLY******

barrier before GAF roof deck protection is installed; DO NOT nail through the flashing.
Secure the flashing by nailing at 18 inches (457 mm) on center just beyond edge of
flashing so that nail heads hold down the edge.
D. Hips and Ridges:
1. Install GAF leak barrier along entire lengths. If ridge vents are to be installed, position
the GAF leak barrier so that the ridge slots will not be covered.
E. Roof Deck:
1. Install one layer of GAF roof deck protection over the entire area not protected by
GAF leak barrier at the eaves or valley. Install sheets horizontally so water sheds and
nail in place.
2. On roofs sloped at 4:12 or greater, lap horizontal edges at least 2 inches (51mm) and
at least 2 inches (51mm) over eaves protection membrane.
3. On roofs sloped between 2:12 to less than 4:12, lap horizontal edges at least 19
inches (482 mm) and at least 19 inches (482mm) over eaves protection membrane.
4. Lap ends at least 4 inches (102 mm). Stagger end laps of each layer at least 36
inches (914 mm).
5. Lap GAF roof deck protection over GAF leak barrier in valley at least 6 inches
(152mm).
F. Deck-Armor™ Application
1. Deck-Armor shall be installed over a clean, dry deck.
2. Install Weather Watch® or StormGuard® Leak Barrier at eaves, valleys, rakes,
skylights, dormers and other vulnerable leak areas.
3. Lay Deck-Armor™ over deck and overlap 3” (76mm) at side laps and 6” (152mm) at
end laps.
4. For exposure to rain or snow, overlap 12” (305mm) at end laps.
5. For side and end laps: fasten Deck-Armor 12” (305mm) o.c. (6” (152mm)o.c. for high
wind areas).
6. For middle of the roll: fasten Deck-Armor 24” (610mm) o.c. (12” (305mm) o.c. for high
wind areas).
7. For exposure to rain or snow, completely cover all side laps, end laps and fasteners
with tape.
8. For long term exposure see complete Deck-Armor installation instructions for side lap
detail.
9. If roof may be exposed to high winds, apply tape over all fasteners at the center of the
roll to prevent rain or snow from entering at the fasteners.
10.For slopes between 2:12 to less than 4:12, a double application of Deck-Armor is
required. See complete Deck-Armor installation instructions for more information.
G. Penetrations:
1. Vent pipes: Install a 24 inch (610 mm) square piece of eaves protection membrane
lapping over roof deck underlayment; seal tightly to pipe.

07310-18
Rev 02/21
 GAF TIMBERLINE SERIES SHINGLES GUIDE SPECIFICATION

2. Vertical walls: Install eaves protection membrane extending at least 6 inches (152mm)
up the wall and 12 inches (305mm) on to the roof surface. Lap the membrane over
the roof deck underlayment.
3. Skylights and roof hatches: Install eaves protection membrane from under the built-in
counterflashing and 12 inches (305mm) on to the roof surface lapping over roof deck
underlayment.
4. Chimneys: Install eaves protection membrane around entire chimney extending at
least 6 inches (152mm) up the wall and 12 inches (305mm) on to the roof surface.
Lap the membrane over the roof deck underlayment.
5. Rake Edges: Install metal edge flashing over eaves protection membrane and roof
deck underlayment; set tight to rake boards; lap joints at least 2 inches (51mm) and
seal with plastic cement; secure with nails.
I.02 INSTALLATION OF SHINGLES
A. 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.
B. Placement and Nailing: ***Recover***
1.
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” (76mm)
to 4” (102mm) rather than a fully exposed shingle.
2. For maximum wind resistance along rakes, 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.
3. Laterally, offset the new shingles from the existing keyways, to avoid waves or
depressions caused by excessive dips in the roofing materials.
4. Using the bottom of the tab on existing shingles, align subsequent courses.
5. *Note: DO NOT install standard sized shingles (5” exposure) over metric (5 5/8”
exposure) shingles, as it will overexpose the shingles and reveal the nails. Use
standard alignment methods to assure proper shingle placement.
6. Secure with 4, 5, or 6 nails per shingle per GAF’s instructions or local codes.
7. Placement of nails varies based on the type of shingle specified. Consult the
application instructions for the specified shingle for details.
8. Nails must be driven flush with the shingle surface. Do not overdrive or under drive
the nails.
9. Shingle offset varies based on the type of shingle specified. Consult the application
instructions for the specified shingle for details.
B. Valleys ***Choose a Method***
