IKO <br /> Installation Instructions for <br /> Asphalt Shingles <br /> Page 2 of 5 <br /> IKO Shingle Application Instructions — 3-Tab Shingles <br /> (ASTM D3161, Class F—IKO Marathon 25 AR and CRC Superglass M25AR) <br /> NOTE: THESE INSTRUCTIONS SHALL BE USED IN CONDUCTION 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 underiayments 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 314"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 cutting into shingle surface. i <br /> NAILING ON STEEP SLOPES:For steep slopes of 21"per foot(60°)or more,use 6 nails per shingle placed i <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 /> i <br /> EXPOSURE: Installed shingles shall have a maximum average exposure of 5-5/8". <br /> i <br /> STEEP SLOPES <br /> o— SEALING STRIP o`—'— o o �`o o o j+I <br /> I 6.t�• 12 I � 6118' I 1 <br /> NAILS NAILS �� <br /> DO NOT NAIL INTO OR ABOVE THE SEALING STRIP j <br /> 4 <br /> I <br /> {I <br /> i <br /> i <br /> f <br /> I <br /> i <br /> PRI Construction Materials Technologies.LLC.6412 Badger Drive Tampa,Fl.33610 Tel:813-621-6777 Fax:813521-58411 e-mail:materialslestingwernLcom WebSile:hllp:/Mnvwprlcmtcom <br /> 1 <br /> I <br /> i <br /> I <br />
