If you choose not to move the roof to a different level revit notifies you later if the roof is too low.
Roof is flat revit.
We cover creating the flat roof adding slopes to roof by using.

Revit then makes the wall meet the underside of the roof correctly.
The revit interface is a bit unclear about constructing a flat roof but no roof is truly flat and creating a flat roof in revit allows the designer to annotate the roof without having to deal with the issues associated with the modeled hips and valleys of a low slope roof.
I ve recently bumped up against this problem and my solution for a flat curb was to use a bit of roof sketched to the required size raised 6 minimum above the main minimally slope.
2 activate slope to create a sloped roof.
On the properties palette set the underlay value to 01 store floor.
To turn a sloped roof into a flat roof select all roof boundaries purple lines and uncheck defines slope in the option bar.
Once again select the wall first 1.
Roof by footprint can be used for both flat and sloped pitched roofs.
In the option bar make sure defines slope is deactivated before drawing the boundary.
Draw a flat roof.
On the options bar set overhang to 0 and clear defines slope.

This video covers how to create a flat roof in revit that contains slopes for roof drainage.

On the draw panel select a sketch or pick tool.
Then choose attach top base 2 and finally select the roof 3.

We can use the same attach top base tool to tidy up this junction.
If you try to add a roof on the lowest level a dialog prompts you to move it to a higher level.
