Wind Uplift

What Is Wind Uplift

Wind uplift is the upward aerodynamic force exerted on a roof surface when wind flows over the structure, creating lower air pressure above the roof than below it, and this pressure differential generates suction strong enough to lift, curl, crease, or tear shingles from the deck. The physics are the same as airplane wing lift: fast-moving air above, higher-pressure air below, and the resulting upward force acts on the shingle surface.

Where Uplift Damage Occurs

Wind uplift is not uniform across a roof. Aerodynamic studies show that roof perimeters (eaves and rakes), corners, and ridges experience two to three times the uplift force of the field area in the center of the roof. This is why wind damage often starts at the edges and works inward. The first shingles to fail are typically along the eave, at the rake, or at hip and ridge lines where turbulence is greatest.

Wind Uplift and Insurance Claims

When documenting wind uplift damage, photograph the pattern of shingle displacement. Lifted, curled, or missing shingles concentrated at edges and corners are consistent with aerodynamic uplift patterns. Note the wind direction from the weather event and correlate it with the damage location. If the wind direction was from the west and the damage is on the western eave and rake, the pattern is consistent. Adjusters evaluate whether the damage pattern matches known uplift behavior or whether it indicates a pre-existing condition like failed adhesive seals.
