Can you tell me if tree roots continue to grow once a tree has matured?

Can you tell me if tree roots continue to grow once a tree has matured? Based on some research I can find where mature trees still grow in girth and maybe height, but it does not talk about the root system. Is there a point where the root system matures and no longer grows?

Roots are as fascinating and they grow as long as the tree grows, they also repair damage. Roots supply water and store nutrients. To keep up with increased demand as the tree gets larger the roots must increase also. The answer to the question if trees grow after they reach mature height is addressed in the 3rd link. The answer is yes and no. Trees continue to increase in girth and add rings each year. They do not exceed their mature
height.
