I am still in the process of building mine. All it has so far is plastic on the top of the hoop and it has not blown over at all nor has the plastic ripped. It even has had a few inches of wet snow on it and still good. I think its heavy enough between the 2x4s and the metal cattle handles to wothstand the wind. I know one we attach the door its going to be even heavier.for those of you that have the hoop coops, do you have any problems with wind or rain damaging the coop? I keep wondering if a wind will be able to blow the thing over once we finish it.
I found a website that has heavy duty, wind/water/artic proof tarps that I am going to purchase for the coop. Clear for the winter months so they as much sun as they can & brown for the spring/summer. I will attach them both and just roll up the one I am not using like a shade. Found some great tarp clips I would like to try to hold the tarp on.
