Estimating How Many Nails for a New Roof
When it comes to estimating materials for building construction it’s helpful to have basic rules of thumb to rely on. Fasteners are that elusive building material that often gets forgotten when doing estimates and accounting for miscellaneous costs.
Every manufacturer has different specifications for their shingles but generally speaking shingles fall into two categories. For standard installation most manufacturers recommend 4 nails per shingle. For high wind zones the general rule is 5 nails per singles.
Number of Nails Per Square of Roofing
This ends up with approximately 320 nails per square for standard installation and 480 nails per square for high wind installations. A typical box of 1-1/4″ coil roofing nails is 7,200 nails. Using this we can come up with an approximate number of boxes of coil nails for each roofing job.
- Standard Installation: 22.5 Square Per Box, if you assume 10% loss then it’s roughly 20 Square Per Box
- High Wind Installation: 25 Square Per Box, if you assume 10% loss then it’s roughly 13 Square Per Box
Also, nails will be used for the drip edges, starters and caps so the 10% loss will likely cover those fasteners as well.
