16x24 shed with lean to roof?

[Husky79]

Hi I am going to build a 16x24 shed with lean to roof, I plan on doing it like this, 12 ft long ribs for half the length instead of a whole 24 ft long ribs as I can only transport up to 14 feet. Yes I am aware that the front and back of each ribs will be almost half inch short each side, but that's okay it will be covered up anyway.

So will this work or will the roof be too weak?

I don't want anything fancy just functional shed to keep all my stuff in there.
