The question is, do you need something which is truly rough, or can you
settle for something which only *looks* rough?

If you only need a small amount of roughness, you can make an otherwise
smooth surface *appear* rough by adding a normal{} to it. This has the
advantage of keeping the modelling simple while still making an object that
looks detailed. It has the disadvantage that the object's shadow is still
smooth, and the fake bumps don't really protrude from the object. But
sometimes it's good enough, and it's definitely easier for a beginner.

If this will work for you, then you should look up "normal" in the
documentation, or look for it in the tutorial in the documentation's
contents.
