TREES & THEIR AFFECT ON BUILDINGS

Trees are one of the most attractive features of our urban and rural environment and many properties are complimented by the presence of nearby trees, hedges and shrubbery.

For most of the time, trees and buildings exist and adapt together in reasonable harmony - but not always!

Problems can arise in a number of ways as trees develop and mature and it is important for a house owner to be aware of any present or future risks likely to affect his/her property investment (and the cost of insuring it)

Some risks are obvious - trees collapse in high winds, particularly older or unhealthy trees; a fully grown plane tree may weigh up to 15 tons and can get up to about 40mph before it strikes the ground, or a building!

Other problems are less obvious and often have "hidden agendas" As a tree grows upwards, its roots grow downwards and sideways, in search of water and support. Tree roots can directly affect a building (eg by damaging foundations) or indirectly (by damaging drains or affecting the water table) resulting in shrinkage, subsidence, settlement or ground heave to nearby property. In many instances, these subterranean problems go unnoticed until tell-tale signs or cracks indicate that all is not well.

It is possible to list our most commonly encountered trees in the order in which they are most likely to affect and influence nearby property by root growth. Willow, Poplar and Oak for example are more likely to cause damage than Beech, Plane or Birch.

Qualified and experienced surveyors can advise property owners of all obvious and potential risks and suggest ways of dealing with problems - whether it is too late or not! This area of property surveying is certainly one where prevention is better than cure and property owners, as well as property buyers, should consider obtaining advice if they have any concerns about the presence of trees.
