I'm trying to create something like the attached sketch of a roof. The lines marked in pink would be raised. I've managed to do it, but generally my meshes are really complex, way more than I feel they should be. I think part of the issue is my loops after adding a Subsurf, which go all over the place.

Out of interest, what would be the right way to go about this? Appreciate the help

You say your problem is a very complex mesh, and yet you already solved the minimal topology for your problem, which you embedded in your question. Just model it - below on gifs:

  1. A default plane, Numpad 7 Top Ortographic Mode, E Extruding, holding ✲ Ctrl to snap to grid.
  2. ✲ CtrlR Add Loopcuts (right-click to cancel sliding it) to create an inner grid where needed (use mouse wheel to change number of cuts), and K Knife tool to make diagonal cuts.
  3. Select unnecessary edges and X Dissolve Edges.

What's left is selecting the horizontal edges that are supposed to be elevated, and GZ moving them up:

Those triangles on ends of the roofs probably should be vertical - can be fixed by just moving their top vertices, but for such case the workflow becomes even simpler:

This time I used an alternate method for diagonal edges - GG sliding vertices. Without Auto Merge enabled, I had to A Select all, and MB Merge By Distance.

    $\begingroup$ Markus — thank you for this — it's a massive help. I think I was over thinking it all and ended up with an obscene amount of vertices... I've just tried your method on a few other letters and it's all worked a lot smoother. Thanks so much for taking the time here. I'm still trying to figure out this stuff, for the most part I get something like I intend, but generally through bodging it badly. I really appreciate you helping me find the right ways! $\endgroup$
