Just like your house, the roots of the tree are its foundation.
The roots bring large amounts of water and nutrients stored in the soil from the ground to the trees canopy. Often in Texas, the clay soil gets compacted or built up around the root collar from construction or landscaping. This causes the phloem to suffocate by reducing the availability of water and nutrients vital to the tree.
To resolve this issue, Leatherface Tree Service uses an Air-Spade to loosen the soil and move it away from the root collar without causing the damage to the small roots a shovel would.
