For areas where the roof slope is 4" per foot or greater, cover the deck with one ply of <br /> underlayment laid parallel to the eaves,with 2"horizontal laps and 4"end laps. Apply metal drip edges on top <br /> of any underlay along rake edges and directly to the deck along eaves in accordance with building code <br /> requirements. <br /> NAILING: Use galvanized(zinc coated)roofing nails, 11 or 12 gauge,with at least 3/8"diameter heads,long <br /> enough to penetrate through plywood or 3/4"into boards. Use 4 nails per shingle placed 6-1/8"above the butt <br /> edge,approx. 1"and 13"from each end and 1/2"above each cutout. Drive nails straight so that nail head is <br /> flush with, but not cuffing into shingle surface. <br /> NAILING ON STEEP SLOPES: For steep slopes of 21"per foot(600)or more,use 6 nails per shingle placed <br /> as shown below. Ensure that no nail is within 2"of a joint/cutodt of the underlying shingle. Seal down each <br /> shingle at time of application with three 1"diameter(approx.size and thickness of a quarter)spots of asphalt <br /> plastic cement placed under the shingle 2"above the bottom edge and equally spaced along the shingle. <br /> Apply plastic cement in moderation since excessive amounts may cause blistering. CAUTION: Shingles <br /> should seal to the underlying course when the factory applied asphalt sealant is sufficiently warmed by the <br /> heat of direct sunlight. <br /> EXPOSURE: Installed shingles shall have a maximum average exposure of 5-5/8". <br /> STEEP SLOPES <br /> =t <br /> 1-irz, 1-ir, <br /> LSEAUNG SW <br /> rA <br /> NAILSNAILS <br /> DO NOT MAIL INTO OR ABOVE THE SEAUNG STRIP <br /> PR(Construction Materials Toonotogies,LLC.6412 Badger Drive Tampa,FL 33610 Tei:813-621-5777 Fax:813-621-5840 e-mail:Mateiialstesfing&demLeom WebS1te:httr.1/www.pdcmtccm <br />
