What type of nail is recommended for attaching sheathing to roof rafters?

Attaching sheathing to roof rafters requires nails that can provide sufficient holding power and durability, particularly in outdoor environments where exposure to weather is a concern. The recommended choice, 16d galvanized nails, is ideal for this application because they are longer (3.5 inches) and thicker than other options, allowing them to penetrate deeply into the rafters and provide better structural integrity for the sheathing. The galvanized coating is crucial as it helps prevent rust and corrosion caused by moisture, ensuring that the connection remains strong over time.

While 8d common nails and 10d ring shank nails are also suitable for various framing applications, they may not provide the same level of fastening strength or protection needed in this specific instance. 6d finish nails, being shorter and less sturdy, are better suited for lighter, more aesthetic applications rather than for securing heavy sheathing materials to rafters, where greater strength and durability are paramount. Therefore, the use of 16d galvanized nails ensures both the integrity of the roof structure and the longevity of the materials used.
