TL;DR
A wind uplift rating is the tested resistance of a roofing product or assembly to the suction forces wind generates as it accelerates over a roof, expressed through standards like ASTM D3161 and D7158 for shingles, with Class F and Class H covering 110 and 150 mph, and UL 580 or FM classifications for membrane assemblies. The forces concentrate at edges, eaves, and corners, which is why fastening schedules tighten there.

Coastal and high-wind jurisdictions, Florida most prominently, write specific classes into code approvals, and insurers in hail and wind states discount premiums for documented higher classes.
