USAGE AND SAFETY INSTRUCTIONS SLATE/SHINGLE SET-UP These are the layout recommendations for Snostop Plus installation on residential slate and shingle roof types – based on the average rafter length of 20 to 25 feet. Recommended adhesives are Surebond SB-190 or equivalent exterior grade construction adhesive for plastic and metal surfaces. 1. Find the ideal spacing for Snostop Plus based on your roof pitch. See Figures 1 & 2. 2. Start the first row 2 feet to the left of area you wish to cover (a doorway, garage, deck etc.) and finish the row 2 feet to the right. 3. Before installation, ensure the head and base of Snostop Plus are securely fastened together 4. Apply exterior grade sealant/caulking (according to manufacturer’s instructions) generously and evenly to the base of Snostop Plus 5. Face the “stop sign” toward the roof peak, perpendicular to the eave. 6. Fasten to roof structure with two #14 stainless steel screws (2” to 2.5” length) with neoprene washers 7. After fastening to roof, seal around entire base of the snow guard with additional sealant

WARNING All spacing and layout recommendations are based on standard snow loads, roof panel lengths and pitches.

USAGE AND SAFETY INSTRUCTIONS METAL ROOF INSTALLATION These are the layout recommendations for Snostop Plus installation on residential metal roof types – based on the average rafter length of 20 to 25 feet. Recommended adhesives are Surebond SB-190 or equivalent exterior grade construction adhesive for plastic and metal surfaces. 1. Find the ideal spacing for Snostop Plus based on the roof pitch. See Figures 3 &4. 2. Start the first row 2 feet to the left of area you wish to cover (a doorway, garage, deck etc.) and finish the row 2 feet to the right. 3. Clean the roof surface with soap and water. Ensure there is no leftover residue from the soap and the surface is dry before installing the snow guards. 4. Before installing Snostop Plus, ensure the head and base are securely fastened together 5. Apply clear adhesive (according to manufacturer’s instructions) generously and evenly to the Snostop Plus base. For galvanized or galvalume roofs use non-acetic acid adhesive 6. Press Snostop Plus for an air tight seal onto the roof with the “stop sign” facing the roof peak (some adhesive may extend out the sides) 7. Optional: Use two #14 stainless steel screws (2” to 2 ½“ length) with neoprene washers to secure the Snostop Plus into the roof structure 8. Seal around the entire base of the snow guard with additional adhesive
