GENERAL INSTRUCTIONS
ROOF DECKS: Use minimum 3/8" (10mm) plywood or OSB decking as recommended by APA-The Engineered Wood Assn. Wood decks must
be well-seasoned and supported having a maximum 1/8" (3mm) spacing, using minimum nominal 1"(25mm) thick lumber, a maximum 6"
(152mm) width, having adequate nail-holding capacity and a smooth surface. Do NOT fasten shingles directly to insulation or insulated deck
unless authorized in writing by GAF. Roof decks and existing surfacing material must be dry prior to application of shingles.
UNDERLAYMENT (LEAK BARRIER): Install GAF leak barrier at the eaves in localities where leaks may be caused by water backing up behind
ice or debris dams.
UNDERLAYMENT (ROOF DECK PROTECTION): Underlayment beneath shingles has many benefits, including helping to prevent wind-driven
rain from reaching the interior of the building and to prevent sap in some wood decking from reacting with asphalt shingles. Underlayment
is also required by many code bodies and is required to maintain the shingles’ UL Class A fire rating. When an underlayment is installed, use
a breather-type underlayment, such as GAF Shingle-Mate
®
or Deck-Armor
underlayments. GAF Tiger Paw
underlayment, with its moisture
control design, can also be used. Always have a design professional review ventilation requirements when using a moisture control
design underlayment.
FASTENERS: 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 surface of the shingle. Overdriving will damage the shingle. Raised fasteners will interfere with
the sealing of the shingles and can back out.
• ASPHALT PLASTIC CEMENT: Use asphalt plastic cement conforming to ASTM D4586 Type I or II.
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. If shingles are
to be applied during PROLONGED COLD periods or in areas where airborne dust or sand can be expected before sealing occurs, the shingles
MUST be hand sealed. See Nailing Instructions / Hand Sealing.
MANSARD AND STEEP SLOPE APPLICATIONS: For roof slopes greater than 21" per foot (1750mm/m), shingle must be hand sealed. DO NOT
use on vertical side walls.
RELEASE FILM: Plastic film strips are present either on the back or face of each shingle. The film strips are to prevent shingles from sticking
together while in the bundle. Do not remove the film strip before or during the application.
THROUGH VENTILATION: For optimal shingle life and to help prevent mold growth, all roof structures must have through ventilation to prevent
entrapment of moisture-laden air behind roof sheathing. Ventilation must be designed to meet or exceed current F.H.A., H.U.D. or local code
minimum requirements. Note: Minimum net free ventilation area of 1 sq. foot per 150 sq. feet (1 sq. meter per 150 sq. meters) of ceiling area
is required. When vents are located at the eaves and near the roof’s peak (balanced) for maximum air flow, ventilation may be reduced to 1 sq.
foot per 300 sq. feet (1 sq. meter per 300 sq. meters).
EXPOSED METAL: Paint all exposed metal surfaces (flashing, vents, etc.) with matching GAF Shingle-Match
roof accessory paint for
best appearance.

INSTRUCCIONES GENERALES
• PLATAFORMAS BASE DE TECHOS: Use una plataforma base de 3/8" (10mm) de madera terciada u madera aglomerada orientada (OSB por
sus siglas en inglés) como mínimo según lo recomendado por la Asociación Americana de Madera Terciada (APA por sus siglas en inglés).
Las cubiertas de madera deben estar bien preparadas y apoyadas, con un espacio máximo de 1/8" (3mm), con un espesor mínimo nominal de
1"(25mm), con un ancho máximo de 6" (152mm), y una capacidad de retención de clavos adecuada y una superficie suave. NO asegure las
tejas directamente al aislante o a la plataforma base aislada a menos que sea autorizado por escrito por GAF. Las plataformas base de techo y
material de superficie existentes deben estar secas antes de la aplicación de las tejas.
• CAPA BASE (barrera contra goteras): Instale barrera de filtraciones de GAF en los aleros en lugares donde el estancamiento de agua detrás de
hielo o desechos podría causar filtraciones.
• CAPA BASE (PROTECCIÓN PARA CUBIERTAS DE TECHOS): La capa base debajo de las tejas tiene muchos beneficios, incluyendo el ayudar a
evitar que la lluvia arrastrada por el viento alcance el interior del edificio y evitar que la savia de algunas plataformas de madera reaccione con
las tejas asfálticas. La capa base también es requerida por muchos códigos de construcción para mantener la calificación Clase A de UL contra
incendios. Donde vaya a instalar una capa base, use una de tipo respirable como las capas base Shingle-Mate
®
o Deck-Armor
de GAF.
También se puede utilizar la capa base Tiger Paw
de GAF, con su diseño de control de la humedad. Siempre pida a un profesional en diseño
que revise los requisitos de ventilación cuando utilice una capa base con diseño de control de la humedad.
• SUJETADORES: Use únicamente clavos de techado de acero o aluminio galvanizados, de calibre 10-12, arponados, deformados o con espiga
suave con cabezas de 3/8" (10mm) a 7/16" (12mm) de diámetro. Los sujetadores deben ser suficientemente largos como para penetrar al
menos 3/4" (19mm) en las plataformas base de techos o apenas a través de las plataformas base de madera terciada. Los sujetadores deben
ser clavados a nivel con la superficie de la teja. Clavar en exceso puede dañar la teja. Los clavos sobresalientes interferirán con el sellado de las
tejas, y pueden doblarse hacia atrás.
