Recently moved into a newly built house.
The storage room is uninsulated and built on a cast foundation.
The roof is tar paper on tongue and groove boards.
See attached image.
The image is taken slightly askew from the side, I see, but the spot we see in the image is in one corner of the roof. (the white is the roof).
What conclusions can we draw about it?

I tried rubbing it a bit with my finger this evening.Hawkai said:
I've also tried washing it with a cloth.
And it disappears when I wash it just like dirt, feels a bit like soil actually.
I've never washed away mold so I don't know what to compare it with
As Hawkai writes, it looks like dirt.
A possible cause:
The storage roof is made of rafter panels or something similar.
There is a clear boundary between the different parts, and the "dirt" is only confined to a small area.
So the reason might be that the rafter panel (or whatever it is) was partially uncovered during transport/storage before the construction was completed and got dirty.
If it were mold, it would likely be more widespread, without such sharp boundaries.
You mention the house is newly built. Has it looked like this since it was constructed?
Who painted the ceiling? When? Why?
It's not common to paint the underside of a ceiling, and no other building parts seem to be painted.
In the right part of the image, there is a strange shadow from the roof down over the "hammer beam" adjacent to the dirty area. What is that?

Knockonwod:
I haven't seen any signs that it was built using tiles, it looks like a whole roof built on raw laths.
I'm actually unsure if it has looked like this for a long time or ever since it was built.
I just looked through old pictures and found an unclear image from a month ago where you can see the "dirty pane" in the roof.
This means it was there when the inspector checked the house, he didn't say anything about it.
I don't know when it was painted.
The strange shading you're writing about I believe is netting to prevent animals from flying in.
There is a gap around the entire storage where the roof meets the wall that is covered with this netting.

Råspontluckor are regular råspont pre-manufactured in large panels, which makes it faster to lay the roof. You won't see any joints on the råspont as you lay the panel joint on the truss. I also suspect that something "dirt" has gotten onto the material, now showing through the paint or causing growth combined with moist air. So if it's true that you have råspontluckor, check that, I agree with KnockOnWood.savio said:
