In my experience with roll pins, I have learned that you do not want to use a "regular" punch. You want to get an actual roll pin punch that is designed for this task that is of the appropriate size. They have a center protrusion that goes inside the roll pin, and an outside shoulder that rides on the roll pin edge and drives it out. Years ago I learned the hard way and mangled up some roll pins (and their receiving holes)trying to drive them out with the wrong tool.

Technically, those pins you have trouble with are Spring pins (they are spring steel, hollow in the middle, formed to shape, slot down the length to allow for springiness) - true roll pins are different in that they are just a piece of steel sheet stock rolled into a barrel and they are typically fairly solid all the way through - Sometimes using a "roll pin punch" can actually mushroom the inner rolls of the steel and wedge it in even tighter - So it is usually advisable to be sure of what type of pin you are working with, and select appropriate punch for the job... (there are also some pins made of solid tool steel, very hard, and will actually deform the ball tip of a roll pin punch.. DAMHIK...)
