The Roofing Nails for a Roof calculator computes the number of roofing nails needed for a roof based on roof dimensions and wind conditions.
INSTRUCTIONS: Choose units and enter the following:
Roofing Nails ( nails R ): The calculator returns the number of roofing nails needed for normal wind conditions and for high wind conditions.
The calculator computes the surface area of the roof. Then it determines the number of shingle squares required to cover the roof in shingles. It then uses the number of squares to compute the number of nails based on 348 nails per square in normal wind areas and 522 nails per square in high wind areas. The difference is in the number of nails used for each shingle. In the diagram of shingles, you can see extra nails below the sealant strip for high wind areas.
High winds are experienced in areas with little cover from wind breaks. Such areas include deserts, prairies, mountain tops and areas adjacent to large bodies of water. High winds are also associated with areas prone to hurricanes.
