Help with Modelling a Curved Roof to Sit on a Curved Wall

I am stuck! I'm very new to the Revit modelling world and am trying to model a roof on a project. The site is quite unique and features a large curved brick wall, but also a nightmare to try and model.

Progress so far and the curved wall behind -

What I want to achieve in section looks a bit like this (note: I'd like the roof to include the window bits)

My first idea was to try and model it in section and extrude the shape all the way through, but that won't work as the extrusion would be linear, when I need it to match the curve of the wall (if that makes sense).

Is there any way I can model it in section on the centre like of the curve and then model it around, to match the curve? (I found the Revolve tool but that looks pretty complicated!) Like this -

Any help would be super appreciated! My knowledge is pretty basic but am very keen to learn how to do this properly 🙂

Sounds like a job for Roof by [Mass] Face. Are you familiar with this method?

Spit balling here; you could do two void extrusions. One in the Y plane to have your section look correct, and then one in the X plane to have it follow your curved wall. I've done this in the past.

Either the Roof by Face method as mentioned above, or an in place roof family made with a revolve and a void (to make it flat across the inner radius.)

Using a revolve and a void to get the straight edge will give a "dip" at the middle of the straight, and the elevation of that edge will be curved, not flat.  From the screenshot I think OP wants it to be flat unless he comes back and says otherwise.
