Try this.
Set you roof to be "Projected with Overhead".
Set it to show on the current storey and however many storeys above that you need to see it.
The "Uncut" line is the one you will see from the storey above and in elevation (also in the current storey if your roof is below the floor cut plane).
The "Overhead" line is the one you will see in the current storey if the roof is above the floor cut plane.
The only problem with this is that the project preference option to show a solid line type for elements above the home storey no longer works.
That only works if you have the roof set to "Outlines only" but then you lose control of the pen colours.
