Your roof line has me curious. Why have a flat section? It seems that one continuos slope would mean one piece of metal that you don't have to tie into another piece at a different pitch. If it was me, I'd add some lumber to the far side of the container roof to raise it to the same pitch as the lean to. 1:12 ?
Something else to consider. Even though the container is water tight, or should be depending on the level of abuse it received, allowing water between your metal roof and the container creates a situation down the road for rot to the wood, mold and bugs. Keeping the water out all the time is the only way to gurantee the life of any building and eliminate long term problems.

Eddie, I used screws for all Simpson ties and tie-ins to the posts. I also used screws on the the blocks that tie to the container. I only used nails on the flat purlins where I'll attach the metal. I shot three nails into each purlin over the lean-to and two on each one on top of the container.
I'll be putting materials shelves on the back side of the container (see attachment). Those shelves will also have a short roof, 6', and run the length of the container. The flat roof (shown in blue) will actually overlap both sides of the container by 6". There will hardly be any gap between the overhang and the sloped metal, 1/2" maximum.
I'm going to shoot sealing type fasteners in the flat roof, so any leakage should be minimum. At 9' wide, I don't think much water will collect. Even in the heaviest rains, the water will run off before it gets even 1/2" deep.
I failed to mention that this is a temporary structure. I've promised Kathy that I'll tear down the lean-to and move the container after I get my shop built. When I move the container, I'll reinstall the flat roof and give it a 4" pitch by blocking it on one side to allow better water drainage. The roof will stay with the container only to keep the internal heat down. I'll paint the sides white.
If I had run the purlins all the way up and across the container, I'd have to have lumber over 22' long. I hauled all this lumber in my pickup because the longest was 14'. The same will be true for the metal. There's something to be said for being able to haul all your material in a pickup and not even fool with a trailer. I have a trailer, but why bother when I can flag my load and carry it easily?
The nice thing is that most of this will just unscrew and come apart without complete teardown. I can move 10' x 14' sections as a unit or completely disassemble them without too much difficulty. That said, I'd bet this will be just like I build it for at least 3 years. Things have a way of filling up and becoming "needed" space. I may have to alter my roofline slightly if it leaks too much or we decide to make it more permanent.
BTW: The cost of wood for this project is $350 and my metal will be about $750 or less. I'll know more later this afternoon. I could get custom metal, but there is a place nearby that sells precut galvalume panels and I've heard they are very reasonable. I may be pleasantly surprised. All the poles, fastener brakets, screws, and nails for my nailgun I've had for years and finally found a use for them.
