What is Wind Uplift?
Roofing Glossary · Damage & Failure
Definition
The aerodynamic force that acts upward on a roof surface, particularly at corners, edges, and ridge areas, during high wind events. Wind uplift is the primary cause of shingle blow-off. Resistance to wind uplift is determined by the shingle's design wind rating, fastener pattern, sealant strip adhesion, and installation quality. Building codes specify minimum wind resistance requirements based on geographic wind zones.
