Our has been out in quite a blow with no damage. The shock system can take a pretty good beating but it is violent and scary to listen to.
If the wind is forecast to be over 15-20 MPH I would roll it up.
If the flapping bothers you, roll it up.
We always roll it up when we are away from camp, just in case a storm blows up and we are not there.
