we just use support poles to hold up the netting it works fine for us.We get alot of snow and freezing rain here. Most of the snow just falls right on thru the freezing rain is more of an issue but, we just shake it off in the morning. THe netting sags alittle but bounces right back. When we remodel the pen we're going to put support beams across the top so it won't sag at all and will hold up to the heaviest snows without any worries.Hope this helps
