ok so I built my coop around my grape arcobour this year and now that winter is coming im concerned about winter proofing it. Ok I will try to make this a simple to inderstand as I can. basically my grape arbor is made of 8 4x4 posts cemented into the ground and 2x4s around the top and latis going across the top for the grapes to grow on and 2x4's across the middle for support. Now I want to figure something easy to do for a roof for the winter. I thought about tarps but then I have to create an angle for water to run off so it doesnt get top heavy and collapse. Keep in mine Im a woman and I am good at everything except building so the easier the better. My husband works 12 hours a day so he wont have time to help me but I do have saws and all that and I can work them. any ideas would be awesome! also I dont want to spend alot.
