When applying asphalt shingles, how far into the sheeting should you drive nails?

When applying asphalt shingles, it is recommended to drive nails 3/4" into the sheeting. This depth is significant because it ensures that the nails penetrate sufficiently to anchor the shingle securely while also allowing for proper sealing of the shingles against wind uplift and moisture infiltration. Driving the nails to this depth helps prevent issues such as blow-offs or leaks around the fasteners, which can occur if the nails are not adequately secured to the underlying structure. The 3/4" depth allows for an optimal balance between holding power and avoiding potential damage to the shingles. This practice is critical in roofing applications to maintain the integrity and longevity of the installation.
