"lean-to" and "flat roof" are different things in my book.

I think it might be a garage with a flat roof?



Correct.


Am I right that the lean to runs the length or width of the garage and
will jut out 3.5m from it?

Yes the length ~6m

In that case, you'll need a strong, heavy
structure to anchor the corrugated sheets to, to stop them blowing away
in a storm, rather than to take their weight.

Well quite sheltered here so snow load would be the daddy. (just
like the original structure I expect)

Can you risk departing from the details here, even though the roof
covering is obviously lighter than the council have in mind?


Mmm :-D
