Pick a cool day and preferably start in the morning when the attic will be cooler. Prepare the work area with boards, lights, and ventilation.
Install adhesive with strips of wood imbedded in the glue along the last rafter or truss at any gable end. Joints made using quarter round strips were about 50% stronger than those formed using only a bead of adhesive.
Apply adhesive along the connection between the roof sheathing and rafters in a continuous bead, much like caulk around a bathtub or apply adhesive to two adjacent sides of 1 by 2 blocks 6 inches long and space them with a 6-inch gap between the blocks. Apply beads or blocks to both sides of the rafters or trusses.
