not very often would you get hit by a tornado or hurricane where you live, but depends of the area your modelling. ?
South west and midwest USA are both susceptable to those weather forces.
Thinking about it, some corregated sheets pointing upwards as if all bent due to serious winds and a definite SERIOUS SWAY 35--45 degree tilt pushed into the structures poles , could bring about a whole new vision. Cannot say if i have ever seen it modelled.
