Need help once again. Lean to style coop and run

How far is spacing for the purlins?

Roofing manufacturer should give specifics for spacing of rafters and purlins.

I have metal roofs on both my coops here in CT & have never had any condensation, but I have good ventilation up high.

Thank you. I would have a 2'x 6' on one end then it would go down in a triangle on both sides. So lots of ventilation

I wouldn't cut the angle too sharp, you want as much space as possible where the rafter meets the wall for soffit ventilation..with a good 18" of overhand beyond wall, then add a fascia to help block the wind.

what I was going to do for the coop is the same design as the run with the 7' wall down to 5' over the 6' width. Then I was going to go up 5' around the whole coop with plywood. (I will try to draw it up. So then the other spots from the 5' and above on the 3 walls would be HWC for ventilation. The front would be all wood.

Looks good!
With leaving the last section separate someday you could close it off to grow grass or clover (if it gets enough sun) for the chickens.

Ya not sure there would be enough Sun. It is shaded with trees. Right now it only has a few dandelions in it. Lol

Got a bit more done.

2x4 skids plus plywood floor plus bedding will make it quite a bit less than five feet high inside the coop. The chickens won't mind and you might not either if you can walk under the high side of the roof. It may affect where you put roosts, nests, feeders, and such. It may also affect what kind of door you can use, especially if you raise the door so the bedding is behind a bit of wall so it doesn't fall out. You may have to build a narrow door and/or cut the end off a door. I like not bumping (or having to watch for) door jams or doing contortions to get in, especially with a shovel or armful of bedding or pails of feed. But a more physically fit/flexible person may not mind so much.

We would cut and make a door. My feed and water is in the run so no worries there. Think if I put nest boxes on the 5' wall then I should be able to walk up to those. I may make them outside of the coop like the ones on my other coop. But even if I need to bend over for a bit of that side that is ok. As I said I am under 5'. So door on tall side since I like my people door in the run too so I have no run away chickens when my dog is out.

But thank you for those points.

Oh one thing I forgot to ask.........

I am doing a metal roof. planning on 2x6's for the beams on the top (can't think of the official name for them) what size purlins would I need??? I think I saw someone doing 1x4's it looked like.......

 

[junior67]

Rafters. 2x6's on edge would be fine.


Yep, that's standard, rafter size doesn't affect purlin size.

Ok thank you. Thought when looking it up I saw some use 2x4's etc. So wanted to be sure I got the right thing. How far is spacing for the purlins? I am doing 24" on the rafters. And what size is best for rafters?
