need help building a flat roof

I want to build a sort of pole barn shed or whatever you want to call it.Its for keeping my wood dry .For the fireplace.
Its going to be 12' wide by 26' long.I put 6x6's in the ground allready.Its 4 in the back and 4 in the front.Its 8'6" in the front and 8'1" in the back.Thats what is sticking out of the ground.
I have sheets of corrigated metal for the roof.
This is where I'am stuck.If I used 2x6's .How do you put them on the poles to hold the roof?
If somebody can show me a picture and tell me what to do.

The 6x6s should have been placed differently but now that you have them where they are, hang the 2x6s between them with joist hangers, front to back. You'll have to cut them on an angle to get the slope that you want but that's ok. Just make them flush to the top of the posts. Then you can screw the metal to them.

First, I would avoid making it flat at all costs! You need some kind of slope.

As Tankerman posted, run your 2x6's the short dimension between the post and nail them on the side of the posts using 4"-6" spikes with your slope. NAil the end ones on the outside of the post. Cut off any post that is sticking above the 2x6 with a hand/power saw.

Run 2x4 perlins on edge, perpendicular to the 2x6's, and toe nail them to the 2x6's aprox 24" o.c. Since your 26' long you will have to overlap boards. IMO they should overlap enough so that ends land on a 2x6 which means that you will need some 16'+ long 2x4's. You may also want a slight overhang on the ends. Your tin will then run perpendicular to the perlins. Another option is to run the perlins between the 2x6's and use hangers to attach them.

For pictures, Google "pole barn framing" in images.

Ah. Go it. He wants a flat roof instead of one that is wavy.
I also misposted. I ment "As Pulpo posted" not Tankerman.
