Alright so I am building a silkie coop. I have the back wall done but now I'm stumped. I'm not sure how to do the roof. And I don't want to build the front wall until the roof is figured out so I need some help. The back wall is 28" high. I began the front wall with the same height. But now I'm not sure how to make a slant for the roof and attach the corrugated metal sheets. They only way I can figure is to nail a 2"x4" up on end on the front wall. Then put 2"x4" slates across then nail on the roof. But then that makes a big gap in the front. And also it wastes a lot of lumber. Here is a badly drawn picture of sort of what the plan looked like in my head. As you can see it's not a good design. I can rip off the front that I started with no trouble. And raise it 4". That takes care of the slant. But how do I put the cross slates on? Putting them on the top makes a big gap. I'm so confused. Please help me. I can get more pictures of what I got so far if needed.
