I have a huge Oak tree growing on the east side of my home in Houston Texas. The tree is about 5 feet from the house and the limbs hang over the roof. The roots are under the foundation and are causing problems. If I remove the tree and the roots are left under the house, will the roots continue to grow from the moisture they suck up?If I have the tree and the roots removed will this cause a gap that may cause the foundation to collapes? Who in Houston is qualified to do the job. Any suggestion will be appreciated.
