Install Roof Sheathing

What happens here

Once all rafters are installed and the fascia boards are in place, the roof structure is ready for sheathing. This typically involves using 4x8-foot sheets of plywood or OSB (Oriented Strand Board). The sheathing panels are laid perpendicular to the rafters, starting from the bottom edge of the roof and working upwards towards the ridge, ensuring that all joints are staggered for structural strength. The panels are securely nailed to each rafter using a nail gun, adhering to specific nailing patterns (e.g., nails every 6 inches along the edges and every 12 inches in the field) as required by local building codes. This creates a robust, continuous surface that adds structural rigidity to the roof and provides a smooth base for subsequent roofing layers like underlayment and shingles.

Goal: Plywood or OSB panels are fastened to the top of the rafters, creating a solid and rigid deck that serves as the base for the final roofing materials.
