Need a small tree like Amur maple but not strong uplifting root system. How is Amur maple?
Answers:
Amur Maple is an excellent low growing tree for small yards. They grow 20 to30 feet tall and create dense shade. Some pruning early is necessary to discourage excessive branchiness. They are popular for Bonsai containers, so I think the root problem shouldn't be a problem to you. Good luck and happy gardening.

Red japenese maple or any kind of japenese maple would be a good small tree plus the roots stay underground
I would do more research on this if I were you, as for there are several different varities of maples, and each has its own characteristics. Some grow more tall than wide, and vice-versa. I have an acer palmatatum (bloodgood) that is about 7 years old, and stands about 12-13' tall with a width of about 15' respectively. This of course is the japanese red maple, and there are other varities that are similiar. Then there is the subject of leaf color, and location of yard to put tree in. Most of the trees that I have don't like direct sunlight, and prefer semi-shaded areas, and enjoy the evening sun versus any other time of day. As for the root system, I know that most maples I have dealt with (especially jap maples) prefer sandy well-drained soils. Of course you can always prune the tree to grow in the direction that you would want it to grow, and might be warranted if putting close to the house. I do also recommend that you fertilize them regularly for better growth. Check out the site below for an idea of what varieties you can choose from, and what to expect with each one.
I personally prefer the dissectum (lacy leaf) varieties of the japanese maples. Crimson queen is the variety that I currenthy have now, and it is absolutely beautiful.
