Once I have trimmed a wall to an object - such as a roof in this particular case, it is still cutting through any objects that it intersects above that operator. It does this with both the trim to roof tool, as well as the SEO tool.
I have a roof with dormers above, and the walls below are cutting through the dormer walls even though they have been trimmed. How can I stop the objects/walls etc. from cutting through other objects once I have trimmed it.

The walls still exist to their original height as you have discovered.
So reduce the height as low as possible - this sometimes helps.
I think there is an automatic setting when you 'crop' to roof.
Another option is to have the elements in different layers with different intersection group numbers.
If the numbers are different, the elements will not automatically trim.

The problem is that I need the wall to be as high as the top ridge of the main roof, which is higher then the dormers. That is the problem I am trying to sort out, I will look into the intersection group number option.. I have not used that before. Thank you!

Could you segment your wall?, so basically step it down along the pitch of the roof? It is not like your wall would actually run through your chimney.

Just to give an explanation of why I think this is happening:
Automatic Priority-based Connections are SEOs just like regular SEOs. However, they are executed before regular SEOs. This is why the Wall cuts itself out of the chimney (Priority-based Connection - automatic SEO) before being cut by the Roof (regular SEO).
So, when an element is the Target of a Regular SEO, Archicad should be smart enough to revisit its Priority-based SEO connections and update them based on the new geometry of the SEO Target element. I guess this functionality is currently not coded into Archicad, hence the above results.

Would it be possible to use a different Building Material for the chimney walls and set a higher Intersection Priority for it than that of the Walls? That would solve the intersection issue.

That would require increasing the IP of the chimney cladding to be higher than that of the wall, which would probably cause other issues where the walls actually intersect.
