The corrugated roof panels come in different colors and last quite a while. They are a poly-based plastic, and are installed over an OSB roof using corrugated roof screws. This coop was built using 4 pressure treated 4x4 posts for the corners and 7 2x6s for the floor structure. I used joist hangers and lag screws to put the floor together. It is covered with 3/4 plywood. The rest of the construction was done with 8 foot 2x4s. I think that we got 45 of them. I'd have to check my notes to be sure. The roof gable is what is called a "6 on 12." That refers to the angle of the roof. In simple terms, for every 12 inches of run, there are 6 inches of rise. The total width of the stucture, from one side to the other is the span. Half the span is the run. Once you know the rise and run, you can figure the length of the rafters using Pythagorean's theorem, "A-squared + B-squared = C-squared." To be honest, I never thought I'd use algebra after high school!
The wall skins are 1/2 inch OSB. It took 6 4x8 sheets for the walls and 3 for the roof. Two of the OSB sheets will have to be ripped lengthwise, making 4 2x8s for the top half of the walls.
Tips: Caulk every seam to make sure water doesn't get in and prime/seal the exterior with Kilz as soon as you can. OSB can soak up a lot of moisture if left exposed. Also, get a carpenter's square. It will come in handy in the beginning to keep the structure square. I had to use an "old school" method when I built gryeyes' coop. It would have been easier with a carpenter's square. Also, a post level is most handy to keep the corner posts plumb and level. I STRONGLY recommend using a frame nailer for the construction. Makes nailing much easier and shaves a lot of time off construction.
PM me if you have any other questions. We are movng, so I will answer as quickly as I can.
