Wind uplift occurs when wind forces create negative pressure on roof systems, potentially causing pavers to become airborne. Even non-hurricane force winds can create sufficient uplift to dislodge pavers, making it a critical consideration for any elevated deck design.

Surprisingly, you don’t need hurricane-force winds to experience uplift issues. When wind blows over a corner of an elevated deck and penetrates the surface, it can create conical vortices (tight wind tornadoes) that generate enough force to dislodge pavers, even at relatively moderate wind speeds.

The most vulnerable areas are typically along the perimeter of the roof, with the highest risk zone located approximately 4 feet from the corners. This is where wind-induced vortices are strongest and most likely to cause initial failure.

Interestingly, parapets under 6 inches can actually increase uplift risks by creating stronger vortices. However, parapets taller than 6 inches generally provide increasing protection against wind uplift. Both solid and porous parapets can help mitigate uplift forces in different ways.

No, paver weight alone is often insufficient. An interconnected, contiguous lockdown system is the most effective solution. This is why Archatrak’s systems focus on creating a unified surface rather than relying solely on paver mass.

Gap width influences pressure equalization speed under the pavers. While larger gaps allow faster equalization, they must be balanced with other factors like pedestal height and overall system design for optimal performance.

Yes, our wind uplift solutions are designed to work seamlessly with non-combustible deck requirements, utilizing steel Incendio pedestals and appropriate materials throughout the system.

Our systems are tested according to ASTM E 330 standards, which determine structural performance under uniform static air pressure difference. The results are certified by Engineering Express and meet rigorous industry standards.

No, our wind uplift mitigation systems are designed to maintain the clean, modern aesthetic of your elevated deck while providing superior protection. The lockdown components are hidden from view and don’t compromise the visual appeal of your design.

Building height, shape, and orientation all significantly influence wind uplift forces. Taller buildings generally experience stronger winds, while building shape affects how wind flows around and over the structure. These factors are detailed in our guide’s building scale considerations section.
