The roof is also ideal for shade in the hot months! Our chickens love to be outside in the rain and hop around in the snow! They stay close to the coop though in deep snow (Buff Orp, Plymoth Rocks, and Rhode Island Reds).... I had to shovel snow drifts out of the run several time this winter even though it has a nice roof (drifting snow). The nice thing is that the coop is built well enough so that I don't get any snow drifting into the coop during a blizzard.
