Morphology
The meaning is directly compositional: 'roughen' (make rough) applied to 'the edges' clearly yields making the edges less smooth, with 'up' functioning as an intensifying particle. This verb + particle + noun pattern is regular and cross-linguistically common, so a B1 learner who knows the constituents should readily infer the meaning.
Etymology
Roughen up the edges comes from a simple craft image. Imagine using sandpaper to roughen up the edges of wood or paper so they become rough and not smooth, giving a handmade or older look. So, the phrase means 'to make something feel less smooth or perfect'.
