This installation guide is written and provided for the use of professional roofing applicators and EcoStar™ Gold Star Authorized Applicators. Contact the technical department for information on warranty availability and the requirements and benefits of the Gold Star program. SPECIAL NOTE: Empire Slate™ has been tested and listed by Underwriters Laboratories as a Class A and as a Class C roofing material (UL 790). Empire Slate has been tested and listed by Underwriters Laboratories as a Class 4 impact resistance product (UL 2218). To maintain the requirements of these tests and their listings the roof system must be installed exactly as stated in this installation guide. WARRANTIES* EcoStar warrants this product to be free of manufactured defects at the time of shipment from EcoStar’s factory. EcoStar will at its option either supply new product or pay the reasonable cost of replacement products found to be defective hereunder. EcoStar’s limited warranties are the only warranties extended by EcoStar with respect to its materials. There are no other warranties, including the implied warranties of merchantability and fitness for a particular purpose. EcoStar specifically disclaims liability for any incidental, consequential, or other damages, including but not limited to, loss of profits or damages to a structure or its contents, arising under any theory of law whatsoever. The dollar value of EcoStar’s liability and buyer’s remedy under this limited warranty shall not exceed the purchase price of the EcoStar material in question. SHADE VARIATION All Empire Slate tiles come with shade variation. EcoStar tiles that have been ordered and supplied to the job site under one EcoStar sales order number are blended at the factory and do not need to be blended onsite before installa- tion. It is always the responsibility of the applicator to make frequent inspections from the ground or other vantage point to ensure that random shading occurs. EcoStar will not be held responsible for correcting the appearance of non-random installations. Roofers must inspect the roof frequently to prevent customer dissatisfaction. NOTE: If EcoStar tiles have been supplied to the job site under two or more EcoStar sales order numbers, all tiles must be blended together on-site before installation. Specific blending instructions can be found at www.ecostarllc.com on the “Resource Library” page. EcoStar will not be held responsible for correcting the appearance of unblended installations. Natural weathering will produce further shade variations, even in tiles appearing to be identical in color when new. TEMPERATURE Like all roofing materials, EcoStar tiles are subject to thermal contraction and expansion. To ensure that they are installed at their normal dimensions, materials should be installed at temps of 45˚F (7˚C) or greater. EcoStar considers any installation when ambient temperatures are below 45˚F (7˚C) to be a “low temperature installation”. If tiles have been stored in tempera- tures below 45˚F (7˚C), they must be restored to a temperature above 45˚F (7˚C) before installation. Ambient temperature should be at least 34˚F (1˚C) and rising. For assistance with low temperature installations, please contact the technical department. SUBSTRATE The tiles should only be installed on a minimum of 15/32” (12 mm) plywood decking, 7/16” (11 mm) OSB or minimum 3/4” (19 mm) tongue and groove decking with end gaps not exceeding 1/4” (6 mm). Contact the technical department for approved alternatives. Under all circumstances existing roof materials must be removed down to the deck, prior to instal- lation. SLOPE Empire Slate is not recommended for slopes less than 3/12 (14˚). On roofs less than 4/12 (18.4˚) and greater than 3/12 (14˚), Empire Slate must be installed with a maximum expo- sure of 6” (152 mm). On roofs 4/12 (18˚) or greater, Empire Slate Traditional tiles may be installed with either a 6” (152 mm) or 7” (178 mm) exposure, while Beveled Edge and Beaver Tail tiles must be installed with a 6” (152 mm) exposure. On slopes of 6/12 (27˚) or greater , Empire Slate Traditional tiles can be installed at an 8” (203 mm) exposure, while Beveled Edge and Beaver Tail tiles can be installed with either a 6” (152 mm) or 7” (178 mm) exposure. Empire Slate Chisel Point tiles must always be installed with a 6” (152 mm) exposure. UNDERLAYMENT Glacier Guard™ or equal must be applied to all eaves, rake edges, hips, valleys, ridges and protrusions. If a Class C roof system has been specified, cover the remaining exposed deck with Aqua Guard™ or equal. If a Class A roof has been specified, GP Gypsum Corporation DensDeck® roof board may be used, or GAF VersaShield underlayment, or EcoStar-approved alternate. If VersaShield is used, it must be applied over the entire roof deck, after the installation of the Glacier Guard. Gold Star Warranty* requires the use of the above mentioned EcoStar specified products. FASTENERS Stainless steel ring shank roofing nails are recommended for application of the tiles. Gold Star Warranty* application requires the use of EcoStar Ring Shank Fasteners. Hand drive and pneumatic coil nails are available. FLASHING MATERIAL EcoStar recommends that flashing be either copper or stainless steel. Flashing metal, however, is not covered by any EcoStar warranty. Like materials should be used when fastening metal flashings. SEALANTS If local codes require the use of a shingle sealant, the only material approved for use with EcoStar tiles is Dow Corning 790 silicone sealant. * See www.ecostarllc.com for available warranties.
