Are these stud walls supporting my roof?

[TheInsulator]

So, let me preface this by saying I'm very much in the planning stage, and will be getting a structural engineer if I do need to remove walls.

All the internal walls upstairs in my mind terrace are stud partitions. They are nailed to the underside of the roof trusses and sat on top of the floorboards. Joists run left to right in the pic.

I'm reasonably confident they aren't load bearing as the span of the trusses is 5m and they are unsupported entirely across the main bedroom.

Any thoughts, or am I being overly cautious?

It's a 1960e build so I'm guessing the term is rafters, not trusses for the roof?

OP,
Why not go into the roof space/loft and find out what is supported?

I've been up but not sure how I could tell if the studs are load bearing or not?

I can see that the header for the wall in yellow below is mid way between rafters and is nailed to noggins, the rest are nailed directly to rafters running parallel or perpendicular.

If it makes any difference the ceilings upstairs have a slight pitch in the ceiling where they follow the eaves before levelling out, so the rafters aren't sitting directly on the top of the front or back walls.

OP,
I think that your best bet would be to bring in a carpenter or a builder for a heads up after you explain what you propose to do?
If you would or wouldn't need a SE I dont know?

What are you thinking about doing?

I always thought that load bearing stud walls had diagonall reinforcement. If it is a load bearing wall I would have expected the ceiling to finish at the wall and not run much into it past the finished surface.
