I apologize for this delayed reply to your gardening question and hope it is still helpful to you.
Live oak should be planted a minimum of 25 feet from a single story home and even further is better. You can prune the lower branches to prevent rubbing on the roof and the larger roots that lift the soil near the surface are not going to be a problem at a distance of 25 feet. However other factors such as where moisture is dependably present will have an effect on where tree roots develop the most growth over time.
Thanks for the question. Best wishes for a wonderful gardening year in 2007. Please stop in again soon!
