Strategically Offset Strapping for Sheathing

What happens here

To ensure that the roof sheathing can still be securely attached despite the rafter-to-rafter strapping being installed beneath it, a specific and crucial technique is employed. The metal strapping is intentionally installed with a 'tiniest bit' of offset from the anticipated main nailing line along the top edge of the rafter. This slight offset creates a narrow, exposed strip of rafter wood, making it possible for the carpenters to 'toenail' the plywood sheathing directly into the solid wood of the rafter. This method effectively bypasses the strapping at the immediate point of fastening, ensuring a direct, strong, and code-compliant connection between the sheathing and the structural rafter. A Bostitch brand nail gun is visibly used for this process, demonstrating the efficiency and precision of fastening.

Goal: Metal strapping is installed on the rafters with a slight offset, allowing roof sheathing to be toenail-nailed directly into the rafter for secure attachment.
