What is the minimum number of fasteners required per shingle in a zone with winds of 140+ mph?

In regions where wind speeds exceed 140 miles per hour, building codes and roofing manufacturers typically require a heightened level of fastener integrity to ensure the roof's durability and resistance to wind uplift.

The requirement for a minimum of six fasteners per shingle in such high-wind zones is based on the principle of enhanced structural stability. This means that each shingle will be more securely attached to the roof deck, minimizing the risk of shingles being lifted or torn away during extreme weather events. The six fasteners distribute the load of the wind more effectively across the roof and prevent localized point failure that can occur when fewer fasteners are used.

In high-wind zones, following these specifications is crucial for maintaining the safety and longevity of the roof, and it reflects the importance of complying with local building codes and installation guidelines provided by the shingle manufacturer. Adhering to these standards not only protects the property but also ensures that the work meets insurance and warranty conditions.
