bitumen roofing
Step One
Identify the structural joist system support for the roof decking system above. Typical joist spacing is 2 ft on center on wood 2x joists or truss joists (structural). Locate the wood rafter or joist below the roof deck. Location can be found either through a stud finder from above or from under deck access (attic in most cases of a 4:12 sloped roof). Blocking is not required if the center of the wood joist is located.
Step Two
Lift the shingle above, if this is an existing roof. Place the hook along the center of the joist below. Align the bottom hole closest to the “bent hook” at the asphalt self adhesive line, as shown. Drill holes with a 7 mm bit for M8x80 or 5/16”x3-1/8” screws. Remove hook.
Step Three
Fill holes with Silicone or other approved water proof sealant. Per Schletter recommended specifica- tions. This will seal the penetration holes. Place the roof hook back in place with the holes aligning.
Step Four
Place a screw by hand in each hole to assure the drilled and hook holes align. Beginning screwing each screw partially to prevent twisting and misalignment.
Step Five
After securing all screws, tightening to the torque as stated on the drawings. Next, cut a piece of self- adhesive asphalt water proof membrane about 6.5” long x 4” wide (enough to extend over all edges of hook that is under the above shingle.) Per Schletter recommended specifications.
Step Six
Press the membrane all around every edge to adhere securely with no gaps or bulges, or folds. Replace the shingle above. Note: adjacent photo on right shows the pre-assembled KlickTop component assembly mounted on the roof hook. This is the standard method of connecting the roof hook to the rails / purlins. It generally arrives slightly tightened on the Roof Hook. You will need to tighten it later for rail installation
