wind damaged roof

Definitely wild. What I've witnessed is high winds running over a roof create lift as an airplane wing does. They start to lift, then "bounce flap" up and down, and then it's WHAM.

Wind force increases exponentially with velocity. The break point is around 50mph, or so it feels; it's really hard to stand in a 50mph wind. At 65mph, the curve goes steep. 70mph, you're getting blown off your feet, you can't stand up. Put that on 5000sf of anything and it's a lot of force.
