Wind Uplift

Wind uplift is the aerodynamic force that tries to peel roofing off your house. As wind flows over the roof, it creates suction — negative pressure — strongest at edges, ridges, and corners. It is suction, not pushing, that rips shingles off.

Uplift attacks the weakest link first: unsealed shingle edges, poorly nailed courses, loose ridge caps, and inadequately fastened flashing. Once wind gets under one shingle, it peels the course like a zipper — which is why blow-offs so often run in neat rows.

Resistance comes from the system, not any single part: proper nailing (count, placement, depth), sealed starter strips, bonded shingle adhesive strips, and hip and ridge caps rated for the wind zone. This is what shingle wind ratings actually certify.

Why It Matters

Most wind damage is installation failure, not material failure. A correctly installed architectural shingle roof resists far more wind than its rating suggests — which is why the installer's nailing discipline matters as much as the shingle brand.

A Maryland Note

Maryland sits in a real wind zone: coastal storms, nor'easters, and severe thunderstorm microbursts. High-wind nailing patterns (six nails per shingle) are cheap insurance here.
