In high wind areas, how can asphalt shingle wind uplift resistance be enhanced?

Increasing the number of fasteners when installing asphalt shingles is an effective way to enhance wind uplift resistance. This is because more fasteners provide greater anchorage for the shingles, securing them more firmly against the roof deck. In high wind areas, the risk of shingles being lifted or blown off by strong gusts is significantly elevated. By using additional fasteners, the shingles can better withstand the forces exerted by the wind, reducing the likelihood of damage.

Additional fasteners create a more robust connection, which is particularly important in regions prone to severe weather. The enhancements not only protect the integrity of the roof but also contribute to overall building safety. In contrast, reducing the number of fasteners or opting for lighter shingles would compromise the roof's stability and performance, especially in adverse weather conditions. Additionally, using a single-layer installation can limit the effectiveness of the roofing system in resisting wind uplift, as there would be less material to catch and hold the wind.
