The Roofing Nail Calculator provides functions to compute the number of roofing nails needed to shingle a roof.  To do so, it computes the surface area being covered which is driven by the shape of the roof.  For this reason, the Roofing Nail Calculator includes the following functions:

• Roofing Nails for a Roof (normal gabled roof)
• Roofing Nails for a Gambrel Roof
• Roofing Nails for a Hip Roof
• Roofing Nails for a Double Hip Roof
• Roofing Nails for a Shed Roof
• Roofing Nails for a Dormer
• Roofing Nail Density in Normal Wind
• Roofing Nail Density in High Wind
• Weight of Roofing Nails

The Math / Science

Roofing nails are used to attach shingles to a sub-roof material such as plywood. There are two recognized patterns for nailing a shingle to a roof.  One is for normal wind conditions, and the second is for high wind environments.  This is shown in the image to the right above.  This effects the number of nails needed for a roofing job.
