~@ 1iMBERtlNtUltrd' ii11iMBERLLlifiO 1iMBE/flJliOO APPLICATION INSTRUCTIONS 5-1W-"3i4'" (133-146'1lin) ~ I I 'To Fasten: Apply fasteners within shaded boxes. (Fastener must NOT be exposed) Require A Six Nail Fastening Pattern? Use the directions above with the following modification: Replace the inner two fastening locations with four fastening placements. Place two fasteners 8" (203mm) from either end +/- 1" (25mm), and place two additional fasteners 15" (381mm) from either end +/- 1" (25mm). 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 capac- ity and smooth surface. Plywood decking as recommended by The Engineered Wood Assn, is acceptable Where a Class A rating IS mquired over decks less than 15/32" thick, an underlayment is required. 00 not fasten shingles directly to insulation or insulated deck unless authorized in writ- ing by GAFMC. Roof decks and existing surtacing material must be dry prior to application of shin- gles. . UNDERLAYMENT: Underlayment beneatll stlingles lias many benefits, II1cluding preventing wind driven rain from reacl1ing tile interior of the buildll1g and preventing sap in some wood deck- ing from reacting with asptlalt sllingles. Underlayment is also requirelf by many code bodies. Consult your local building department for its requirements. Where an underlayment IS to be installed, a breather-type underlayment such as GAFMC's Silingle-Mate" underlayment is recom- mended. Underlayment must be installed flat, without wrinkles. . FASTENERS: Use of nails (rattler Ulan staples) is recommendelt. Use oniy Zinc coated steel or alurl1lnlJm, 10-12 gauge, barbed, aeforrnea or srnooth stlank roofing nails with heads 3/8" (10mm) to 7/16" (12mm) in diameter. Fasteners Sllouid be long enougn to penetrate at least 3/4" (19mm) into wood decks or Just through fhe plywood decks. Fasteners must be driven flush with the sur- face of the stlingle. Over driving willllamage the stlingle. Raised fasteners 1'1111 interfere with the sealing of the stlingles. If tire temperature IS below 40' F or In areas where alfburne dust or sand can be expected before sealing occurs sllingles must be hand sealed (see WIND RESISTANCE/HAND SEALING). .WIND RESISTANCE/HAND SEALING: Tlwse shingles have a special tlwrrnal sealant trlat firmly bonds the sllinCJles togethor atter application wilen exposed to sun and warm tempera- twes. Shingles instalied in Fail or Winter may not seal until the followlllg Spring. If shingles are dam- agert by Wifllls before sealrng or are not exposed to adequate surface temperatures, or if the self- seaiant gets dlrly, tile sl11ngle5 may never seal. Failure to seal unrJer these circumstances results from the nature of self-sealing shingles and is not a manufacturing defect. To insure immediate sealing, apply 4 quarter-sized dabs of shingle tab adhesive on the back of the shingle 1" (25mm) and 13" (330m'll) in from eacll side and 1" (25m'll) up from bottom of the shingle. The shingle must be pressed firmly into the adhesive. NOTE: Application of excess tab adheSive can cause blistering of the shingle. For maximum wind resistance along rakes, cement shingles to underlayment and each other in a 4" (102m'll) width of asphalt plastic roof cement. NOTE: The tilm strips on the back of each shingle are to prevent sticking together of tile shingles while 1f1 the bundle. Their removal is NOT required during application. . CANADIAN COLD WEATHER APPLICATIONS: CSA 123.5-M90 mandates tl1at sllin- gles 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 appli- cation of that adheSive. . MANSARD AND STEEP SLOPE APPLICATIONS: For root slopes greater than 21" (1750mm/m) per foot (do NOT use on vertical Side walls), shingle sealing must be enhanced by hand scaling. After fastening the shingle in place, apply 4 Quarter-sized dabs of shingle tab adhe- sive as indicated in Wlild Resistance above. The shingle must be pressed firmly into the adhe- sive. . EXPOSURE: 5" (127mm) . THROUGH VENTILATION: All roof structures must be provided with through ventilation to prevent entrapment of moisture laden air bel1ind roof sheathing. 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.
