We are getting ready to add the lean-to roof and we don't know what type to put on it. Our budget was blown weeks ago, so something cost effective is key. We are in Kentucky, where summers reach over 100 (plus high humidity) and we get our fair share of snow in the winter-- it's a 4x8 coop, but will obviously need an overhang. What do my fellow BYCers use? And what materials are needed? Right now, it has nothing- no rafters, no plywood... So it really is a blank canvas. Post pictures of you have them! Thanks!
