I KQ <br /> Installation Instructions for <br /> Asphalt Shingles <br /> Page 3 of 5 <br /> IKO Laminated Shingles Application Instructions <br /> (ASTM D3161, Class F—Cambridge, Cambridge HD, and CRC,Biltmore AR) <br /> NOTE: THESE INSTRUCTIONS SHALL BE USED IN CONJUCTION WITH IKO'S PUBLISHED <br /> APPLICATION INSTRUCTIONS AND THE APPLICABLE CODE. IN THE EVENT THE INSTRUCTION <br /> CONFLICT,THESE INSTRUCTIONS WILL GOVERN. <br /> ROOF DECK: Solidly sheathed and fastened deck conforming to 2017 FBC. <br /> UNDERLAYMENT:Applied in accordance with building code requirements. For areas where the roof slope is <br /> less than 4" per foot down to 2" per foot, use 2 layers of underlayment conforming to building code <br /> requirements,the first sheet overlapping the eave protection by 19",followed by full 36"widths overlapping <br /> each preceding course by 19"or other Approved underlayments in accordance with the qualified application <br /> instructions. 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 in the nail line 7-3/8" <br /> below the top edge, approx. 1"and 13" in from each end. Drive nails straight so that nail head is flush with, <br /> but not cutting into shingle surface. <br /> NAILING ON STEEP SLOPES: For steep slopes of 21"perfoot(60°)or more,use 6 nails per shingle placed <br /> as shown below. Ensure that no nail is within 2"of a joint/cutout 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 5-7/8". <br /> NAILING-STEEP SLOPES APPLICATION <br /> Use six nails as shown_ <br /> —► w t^ � .fir � ��� � �► r 1V —► � <br /> NAIL LINE - <br /> 6 378 t w. <br /> 01 11 f] <br /> NAILS CEMENT <br /> PROPER APPLICATION REQUIRES THAT THE NAILS PENETRATE BOTH THE OVERLAY.AND UNDERLAY PORTIONS OFTHE SHINGLE <br /> PRI Construction Materials Technologies,L-C.6412 Badger Drive Tampa,FL 33610 Tel:813-621-5777 Fax:813-621-5840 e-mail:materialstesting@p6cmtcom WebSite:httpJ/www.prlcmt.com <br />
