Q Will the roots of my tree cause damage to my building?
A Damage to structures as a result of tree roots is not inevitable and is far less common than many people believe. If it does occur the consequences can be very serious.
Subsidence is a possibility only if the local soil is shrinkable (some clay soils shrink as they dry out).
Damage to buildings by the growth and expansion of roots is rare and only occurs if the tree is very close to the building (within one to two metres). Damage to lightly loaded structures such as paths, driveways and garden walls is more common.
The Tree Advice Trust has published a range of research and practice notes giving information and guidance on tree roots and their interaction with built structures. (see publications)
