In short – yes, tree roots can affect development.

How do tree roots affect development?

Tree roots affect development by causing disturbance in the soil, which can cause the soil to become structurally unsound. Any building work or development which takes place within the influence of a tree’s roots can cause damage to the tree or can lead to the development being structurally unsound.

How can I check for tree roots prior to development?

The influence of the tree’s roots can be calculated as part of a tree survey. This is done by examining the height of the tree and the crown spread which can then be used to calculate a Root Protection Area. The examination will show where the roots are most prevalent, and most likely to cause damage to buildings.

Veteran or ancient trees may have a larger than expected Root Protection Area, given their increased age and the increased complexity of their root systems.

What’s a tree survey?

Tree Surveys are a specialised survey that assess the size, age, health and life expectancy of a tree that has a diameter of over 75mm. They then provide recommendations on the further treatment of the tree and whether it should be retained or removed from a site. As part of our tree surveys, ProHort will map the Root Protection Area of any tree, as well as providing a recommendation for protective fencing. Do you have ancient trees, on your property? We can also identify them in your survey report. If we are surveying a group of trees, we will show the root protection zone and fencing in the clearest possible way, to ensure that you have the best plans possible in order to go ahead.

When looking to proceed with any development work, it is crucial that you ensure no roots lie under the proposed site. The safety of the site, and safety of your team depend on it.
