How should you drive the nails that hold aluminum siding to the wall sheathing?

Driving the nails that hold aluminum siding to the wall sheathing should be done snugly. This means that the nails should be driven such that they secure the siding while allowing for some movement, which is important due to the thermal expansion and contraction of aluminum materials. If the nails are driven too tightly, it can cause the siding to buckle or warp, as it won't be able to expand and contract freely with temperature changes.

Using a snug fastening technique ensures the aluminum siding remains securely attached to the structure while accommodating the natural movements that occur with temperature fluctuations. Therefore, this method is critical for maintaining the integrity and aesthetics of aluminum siding installations.
