In high-wind areas, how many fasteners are typically required for most shingles?

In high-wind areas, using six fasteners for most shingles is recommended to ensure they remain securely attached during extreme weather conditions. This practice provides additional holding power to help prevent the shingles from being lifted by strong winds. High-wind zones are often subject to harsh environmental conditions that can compromise roof integrity, which is why the increased number of fasteners is crucial.

Using six fasteners allows the shingles to be anchored more thoroughly, distributing the attached force over a larger area and reducing the likelihood of movement or blow-off. This is particularly important for the longevity and functionality of the roofing system in regions frequently affected by severe storms or high winds. Therefore, the requirement for six fasteners reflects installation best practices aimed at durability and safety in high-risk areas.
