Playing good rolls is part natural talent and part practice. I am quite lucky in that I found from an early age, my brain just seemed to “get” how to do a roll.
Some tips that help me include staying calm, staying loose, using plenty of pressure between thumb and pointer finger (where I am grasping the stick), and I also use fairly high tension on my drum heads. In fact sometimes the heads are so tight that are like playing on concrete! I picked that up from the marching band days back in high school when we had the drum heads tuned extremely tight.
