Roots Of Trees Growing Toward Slab Of Foundation

Q: I have a solid slab foundation under my home. The roots of a tree near the house are growing toward my slab. What should I do? 

A: I think the tree roots are not growing toward your slab, they are simply growing away from the tree. Tree roots grow towards places that offer moisture or nutrients or oxygen. Your slab has none of these. If the tree were growing extremely close to the slab, its roots might crack it due to the normal swaying of the tree lifting the roots. But if your tree is several feet away, the roots won’t harm the slab because they won’t grow underneath it.
