INSTALLATION STEPS Empire Slate tiles are designed and manufactured to duplicate the look of natural slate. 1. Install Glacier Guard in all valleys, eaves, rake edges, hips, ridges and protrusions. Gold Star Warranty* application requires the use of Glacier Guard. 2. Install a minimum of 30 lb (13.6 kg) (ASTM D226 Type II or ASTM D4869 Type IV) felt over the remaining area of the deck surface. If a Class C roof is required, the 30 lb (13.6 kg) felt or equal must be UL listed. Gold Star Warranty* application requires the use of EcoStar Aqua Guard underlayment for a Class C roof system. If a Class A roof is required, install GAF VersaShield® or equivalent over the entire deck including areas already covered by the Glacier Guard. Gold Star Warranty* application requires the use of GAF VersaShield, or EcoStar-approved alternate, for a Class A roof system. 3. Install metal edging at eaves and rake edges. Any corrosion resistant metal edging is acceptable. Copper and stainless steel are recommended. It should be noted that EcoStar Warranties do NOT cover metal flashing. Note: When using copper and stainless steel flashing material the appropriate corresponding nails should be used. 4. A critical step is BENDING. Every tile that is installed must be bent in a downward arch before applying it to the roof deck. Whatever position the tile is in when fastened to the roof deck, is the position it will maintain. It is recommended that each member of the installation crew be instructed on how to bend the tile to insure that it lies flat when fastened to the roof deck. While grabbing the top of the tile (textured side up) with the right hand and the bottom edge of the tile with the left hand, bend the tile in a downward motion until the tile maintains arch. The tiles must be curved under when installing. 5. Beginning at the eave edge, install a starter row of tiles with two nails per tile (in location shown on tiles). 11/2” (38 mm) long stainless steel ring shank roofing nails are recommended. Gold Star Warranty* application requires the use of EcoStar Ring Shank Fasteners. Maintain a minimum 3/8” (10 mm) gap between starter tiles. 6. When using pneumatic nailing equipment, frequently check both the depth and pressure setting, so nails are not over driven, causing tiles to lift. Lifted tiles will diminish the aesthetic appearance of the finished roof system. The nail should not dent the tile. 7. The initial layer of tiles becomes the starter row. This layer will be completely covered by the next row to be installed. The starter row may be installed either front side up or back side up. When the first course of tile is installed, tiles must be offset half a tile to cover the nails from the previous row. A minimum of 3/8” (10 mm) is required between tiles and between tiles and protrusions. 8. CAUTION: Do not install the tiles with an upward curl. Whatever position the tile is in when fastened to the roof deck, it will maintain that position. It is required that each member of the installation crew be instructed on how to bend the tile manually to insure that it lies flat when fastened to the roof deck. 9. As the tiles are installed up the roof, the tile must be cut at rake edges, valleys and projections. The tiles may be cut using a straight edge and a utility or roofing knife. Once the tile has been scored with a knife it can be snapped along the scored line. 10. As the tiles are installed up the roof slope, it is recommended that lines be snapped both horizontally and vertically. The horizon- tal lines will keep the tiles looking straight and uniform. The vertical lines will keep the space between the tiles in line from row to row. DO NOT USE RED CHALK. Red chalk will stain the tiles. 11. CAUTION: As the tiles are installed up the slope of the roof, the installation should be constantly checked from the ground to ensure there is no patterning developing and proper blending is occur- ring. The warranty does NOT cover the aesthetic appearance of the Niagara Shake roof installation. It is the responsibility of the applicator to ensure that color/shading and quality of workmanship meets the aestheticexpectations of the home/building owner. 12. Continue to install the tiles up the roof slope. Be sure to place the nails directly in the position noted on the tiles. Stainless steel ring shank nails are recommended. For 10” (254 mm) Empire Slate tiles, there are two ways to install: 1) the entire project is 10” (254 mm) tile and the installation is the same as the current 12” (305 mm) specification or 2) for a 10” (254 mm) and 12” (305 mm) blend, mix the two sizes together for desired random width look. Take caution when installing to ensure enough coverage past nail heads of previous course. Tiles can be slippery when wet, caution should be exhibited with early morning dew, frost and after rain. EcoStar suggests the use of toe boards, OSHA approved harnesses and safety equipment at all times. 13. When all tiles have been applied to the roof slopes, the pre- formed Empire Slate Hip & Ridge tiles are applied to all hips and ridges. Empire Slate Hip & Ridge tiles are always installed with a 6” (152 mm) exposure with two 2” (51 mm) or 21/2” (64 mm) nails per tile. The use of ridge venting systems is highly recom- mended. Mushroom cap style vents may be used, but ridge venting provides better venting and improves the aesthetic appearance of the roof system. Ridge venting must be installed before installing the Empire Slate Hip & Ridge. When installing over ridge vent, Hip & Ridge tiles are installed with 21/2” (64 mm) nails. 14. As work progresses up roof slopes, care should be taken to mini- mize traffic over completed areas of the roof. The tiles will show any mud or dirt tracked across them. This will cause aesthetic issues with the completed appearance of the roof. It is the responsibility of applicator or building owner to remove this mud or dirt. A mild detergent should be used in combination with a bucket of water to remove the mud or dirt. Clean water can then be used to finish the cleaning process. Do not use any chemicals or solvents without first checking with the EcoStar technical department. EcoStar is not responsible for the cleaning of any tiles. *See www.ecostarllc.com for available warranties. Empire Slate Installation Guide PLEASE REMEMBER TO BEND TILES
