Pretty significant, I'd imagine even without flying debris. There's often an air gap in between the roof and panel which is going to make things really exciting in 100+mph wind. Maybe building codes could be updated so that there's an airfoil on the outside edge of rooftop installations, like on your car's sunroof, to reduce the likelihood of liftoff?
