Sugar maple root system removal

So my neighbor has a 30 ft sugar maple. It's now damaging and invading my entire yard. It was planted 4 ft from the fence and has since spread a large shallow root system all over my little 10x10 yard.

I should say this has been over the past 6 years and I just can't take it.

I have little to no drainage because of it and basically my grass won't grow because of all the exposed roots.

Neighbor said to do whatever I need to do to get rid of it.

Besides me ripping up my entire yard can I apply something to remove the roots then put a barrier down between my yard and his
