How many nails or staples should hold each composition roof shingle in high-wind installations?

For high-wind installations of composition roof shingles, the correct number of nails or staples is six. This requirement is based on the need for enhanced durability and resistance to wind uplift. The additional fasteners provide greater holding power and reduce the risk of shingles being blown off during severe weather conditions.

Using six nails not only ensures that the shingles are adequately secured but also follows guidelines established by roofing manufacturers and building codes, which strive to enhance the performance of roofing systems in high-wind areas. This practice is especially important in regions where strong gusts of wind are common, thereby minimizing potential damage and ensuring the longevity and effectiveness of the roofing.

Other options fall short of providing the necessary support and fastening integrity recommended for safeguarding roofs in such environments.
