If mechanical fasteners are used, how many nails are typically used to secure a tile in place if the slope is 8:12?

  1. 1

  2. 2

  3. 3

  4. 4

The correct answer is: 2

In roofing applications, particularly with sloped installations like an 8:12 pitch, the number of mechanical fasteners, such as nails, used to secure tiles is important for ensuring stability and performance against various weather conditions. For a slope of 8:12, which is a relatively steep pitch, it's standard practice to use two nails per tile. This configuration provides sufficient holding power to secure the tiles while allowing for expansion and contraction due to temperature changes. Using two nails helps distribute the load and provides additional resistance to wind uplift, which is particularly crucial on steeper roofs where wind forces can be more pronounced. Using more than two nails could be overkill for this slope and might not be necessary unless specified by particular product guidelines or regional building codes. Therefore, securing a tile with two nails strikes a balance between adequate attachment and efficiencies in both labor and material usage.
