For securing shingles in high-wind areas, using more fasteners helps to achieve what?

Using more fasteners when securing shingles in high-wind areas enhances the wind resistance of the roofing system. This practice is crucial because high-wind conditions can exert significant forces on shingles, potentially causing them to lift or tear away from the roof. By increasing the number of fasteners, each shingle is held more securely in place, reducing the likelihood of wind-related damage. This technique ensures that the roofing is better equipped to withstand severe weather, which is especially important in regions prone to hurricanes and strong storms.

While better insulation and aesthetics may contribute to overall roofing performance or appearance, they do not directly relate to the functionality of shingles in high-wind situations. Additionally, using more fasteners could potentially lead to higher installation costs rather than lower them, in contrast to the notion of reduced expenses. Therefore, the focus on increased wind resistance through additional fasteners is the key focus in securing shingles effectively in challenging environments.
