That's why it is best to use pavers rather than concrete under flagstone for
example. You can reset the pavers in the future if required.
Removing a lot of roots not only will hurt the tree but leave it weakened in
such a way as it may topple in a high wind or heavy snow. Not advised to
cut larger roots. If you had a few 2" roots maybe but not a big one.
Fortunately in a mature tree, these largest roots will probably not move
much. If the tree were younger and had more to grow I would be more
worried. Do you have a sense if it is already full size?
You can raise the level of the patio by an inch or two by using more sand
and base rock, this will help by buffering the roots deeper, the sand will
be easier to redistribute in the future if you need to reset the pavers.
