To the north-northwest of Roche is the crater Eötvös, and just to the west-northwest lies Rosseland.

The rim as a whole is worn and eroded, with multiple tiny craterlets marking the surface.

The interior floor of Roche is relatively level, but is also marked by several small and tiny craterlets.

Sections of the floor along the north-northwestern side have a lower albedo than elsewhere, usually an indication of basaltic-lava flows similar to what fills the lunar maria.

By convention, these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Roche.
