the roots of the trees are exposed
Will it hurt the trees to add 1-2 feet of soil around them so I
can mow around them?

Don't know what part of the country you are in, but I'd guess maybe
the trees
are Arizona Ash which are famous for putting roots out at grpund
level.

If they are Ash trees, they are pretty much worthless and you may
want to consider taking them out and putting in a better tree.

At any rate, if the tree is worth saving, put no more than a couple
inches of dirt around it. Any more will eventually kill the tree.
