GENERAL INSTRUCTIONS
• ROOF DECKS: For use on new or reroofing work over well-seasoned, supported wood deck,
tightly-constructed with maximum 6” (152mm) wide lumber, having adequate nail-holding capaci-
ty and smooth surface. Plywood decking as recommended by The Engineered Wood Assn. is
acceptable. Where a Class A rating is required over decks less than 15/32” thick, an underlayment
is required. Do not fasten shingles directly to insulation or insulated deck unless authorized in writ-
ing by GAFMC. Roof decks and existing surfacing material must be dry prior to application of shin-
gles.
• UNDERLAYMENT: Underlayment beneath shingles has many benefits, including preventing
wind driven rain from reaching the interior of the building and preventing sap in some wood
decking from reacting with asphalt shingles. Underlayment is also required by many code bod-
ies. Consult your local building department for its requirements. Where an underlayment is to
be installed, a breather-type underlayment such as GAFMC's Shingle-Mate
®
underlayment is rec-
ommended. Underlayment must be installed flat, without wrinkles.
• FASTENERS: Use of nails (rather than staples) is recommended. Use only zinc coated steel or
aluminum, 10-12 gauge, barbed, deformed or smooth shank roofing nails with heads 3/8” (10mm)
to 7/16” (12mm) in diameter. Fasteners should be long enough to penetrate at least 3/4” (19mm)
into wood decks or just through the plywood decks. Fasteners must be driven flush with the sur-
face of the shingle. Over driving will damage the shingle. Raised fasteners will interfere with the
sealing of the shingles. If the temperature is below 40° F or in areas where airborne dust or sand
can be expected before sealing occurs shingles must be hand sealed (see WIND
RESISTANCE/HAND SEALING).
• WIND RESISTANCE/HAND SEALING: These shingles have a special thermal sealant that
firmly bonds the shingles together after application when exposed to sun and warm temperatures.
Shingles installed in Fall or Winter may not seal until the following Spring. If shingles are damaged
by winds before sealing or are not exposed to adequate surface temperatures, or if the
self-sealant gets dirty, the shingles may never seal. Failure to seal under these circumstances
results from the nature of self-sealing shingles and is not a manufacturing defect.To insure imme-
diate sealing, apply quarter-sized dabs of shingle tab adhesive on the back and at the corner of each
tab. The shingle must be pressed firmly into the adhesive. For maximum wind resistance along
rakes, cement shingles to underlayment and each other in a 4" (102mm) width of asphalt plastic
roof cement.
NOTE: Application of excess tab adhesive can cause blistering of the shingle. The film strips on the
back of each shingle are to prevent sticking together of the shingles while in the bundle. Their
removal is NOT required during application.
• CANADIAN COLD WEATHER APPLICATIONS: CSA A123.5-M90 mandates that
shingles applied between September 1 and April 30 shall be adhered with a compatible
field-applied adhesive. See Wind Resistance for GAF Materials Corporation’s recommendations for
the application of that adhesive.
• MANSARD AND STEEP SLOPE APPLICATIONS: For roof slopes greater than
21" (1750mm/m) per foot (do NOT use on vertical side walls), shingle sealing must be enhanced
by hand sealing. After fastening the shingle in place, apply 2 quarter-sized dabs of shingle tab adhe-
sive on the back of each tab as indicated in Wind Resistance above. The shingle must be pressed
firmly into the adhesive.
• EXPOSURE: 5" (127mm)
• THROUGH VENTILATION: All roof structures must be provided with through ventilation to
prevent entrapment of moisture laden air behind roof sheathing. Proper ventilation is also
necessary to help prevent mold growth. Ventilation provisions must at least meet or exceed
current F.H.A., H.U.D. or local code minimum requirements.
• NON-CORRODING METAL DRIP EDGES: Recommended along rake and eave edges on
all decks, especially plywood decks.
• ASPHALT PLASTIC CEMENT: For use as shingle tab adhesive. Must conform to ASTM
D4586 Type I or II .
