Can Tree Roots Damage My Property?
Yes, tree roots can sometimes contribute to damage around a property, but the risk is often misunderstood. Most trees growing near buildings cause no structural damage. Problems are more likely where there are shrinkable clay soils, older or shallow foundations, leaking drains, or hard surfaces and lightweight structures close to expanding roots.
Quick Answer!
Yes, but usually indirectly. On shrinkable clay soil, a large plant can draw moisture from the ground during dry periods, contributing to soil shrinkage and possible foundation movement. Roots can also exploit defects in drains and lift paving or lightweight structures. According to the RHS, however, most trees near buildings cause no damage.
Understanding How Roots Damage
There are three main ways roots may be associated with property problems: movement in shrinkable soil, interaction with damaged drainage systems, and direct pressure on lightweight surfaces or structures.
When Tree Roots Contribute to Subsidence
They can be one contributing factor in certain ground conditions. Subsidence occurs when the ground beneath a building sinks and the foundations move with it. The Association of British Insurers says clay soils are particularly vulnerable because their volume changes as their moisture content changes. Trees and large shrubs can increase moisture loss from clay soil, especially during prolonged dry weather.
Tree-related subsidence is not simply a question of how close a trunk is to a wall. Risk depends on:
-
Soil type and how shrinkable it is.
-
Species, size, age and water demand.
-
Distance between the plant and the building.
-
Foundation depth and construction.
-
Weather conditions, particularly prolonged dry periods.
-
Drainage defects or other ground conditions around the property.
Older buildings with relatively shallow foundations can be more vulnerable in some circumstances. The RHS notes that modern buildings are less commonly affected and that structural damage linked to trees is generally associated with shrinkable clay soils.
Direct Effects of Trees Damaging Foundations
Direct penetration of sound, substantial foundations is much less common than many homeowners assume. Roots tend to grow through soil and along paths where air, moisture and space are available. The RHS states that roots are unlikely to directly penetrate sound footings.
A more realistic concern is ground movement around foundations in shrinkable clay, or roots affecting lighter structures nearby. Visible roots beside a property should not be treated as proof of foundation damage.
If you are worried about movement, arboricultural assessment may form part of the investigation, alongside appropriate building advice and, where relevant, your insurer.
Drains and Drainage Problems
Yes, they can enter drainage systems where there is already a defect, such as a leaking joint, cracked pipe or damaged seal. Moisture escaping from a drain can encourage root growth towards the problem area.
The RHS advises that watertight drains are generally not troubled by roots, while older drains with poor seals and rigid joints are more susceptible.
Finding roots inside a drain does not necessarily mean the root created the original defect. A CCTV drain survey can help identify cracks, failed joints or other faults when blockages recur.
Root Damage to Patios, Paths and Garden Structures
Yes. Surface roots and expanding woody roots can lift paving, edging, small retaining features and other lightweight structures. This is one of the more visible forms of root problems.
Cutting major roots without assessment can destabilise or seriously harm a tree, so do not simply sever roots because paving has moved.
Signs of Root Damage Around a Property
Some signs deserve investigation, but none of them proves that a tree is the cause.
Potential warning signs include:
-
New diagonal cracks around doors or windows.
-
Cracks that appear both internally and externally.
-
Doors or windows that suddenly begin to stick.
-
Paving, kerbs or lightweight garden structures lifting near visible roots.
-
Repeated drain blockages where roots are found during inspection.
-
Noticeable ground movement during or after prolonged dry periods.
The ABI says subsidence cracks often appear suddenly and may be diagonal, while cracks wider than 3 mm can justify further investigation. It also stresses that many cracks have causes other than subsidence.
For context, the ABI reported £72 million in UK domestic subsidence payouts in the second quarter of 2026, with the average claim reaching £20,000.
Diagnosis matters. Pruning or removing without establishing the cause may fail to solve the problem.
Tree Removal and Suspected Root Damage
Not automatically.
Removal can be appropriate in some cases, but it should be based on evidence rather than suspicion. A healthy tree may not be responsible, and removing a mature tree can change soil moisture conditions.
On shrinkable clay, the RHS notes that sudden removal can, in rare cases, be associated with heave, where clay rehydrates and expands.
A better process is to:
-
Record the damage and when it appeared.
-
Check whether drains are leaking or damaged.
-
Establish the soil type and building foundation information where possible.
-
Obtain structural or insurance advice if movement is suspected.
-
Have the plant inspected by an experienced professional.
-
Check whether the tree is protected before carrying out work.
-
Choose pruning, monitoring, root management or removal only when the evidence supports it.
If you need an arboricultural view of a plant’s condition, location and management options, M.A.C Tree Care can help through our surveys and consultancy service.
The Role of Pruning in Managing Root-Related Problems
Pruning may form part of a wider management plan, but it should not be presented as a guaranteed cure for subsidence.
Repeatedly cutting a tree hard simply because it stands near a building can damage its health, encourage unsuitable regrowth and still fail to resolve the underlying cause. Where management is appropriate, work should be specified for the individual and site, with options such as selective pruning, crown reduction or monitoring.
You can learn more about professional pruning options on our pruning service page.
What to Do When Roots Grow Close to Foundations
Visible roots are not, by themselves, evidence that the foundations are being damaged.
For suspected structural movement, contact your buildings insurer before arranging major remedial work. The ABI advises homeowners who suspect subsidence to notify their insurer, who may arrange specialist investigation where appropriate.
An experienced professional can assess the tree and practical management options. Complex cases may require arboricultural, structural, drainage and soil evidence to be considered together.
Why Cutting Roots Can Create Bigger Problems
Root cutting should never be treated as a routine DIY fix.
Removing significant roots can weaken or destabilise a tree.
The impact depends on the size and position of the roots, species, and condition. The RHS advises seeking professional help before anything beyond minor root cutting.
There can also be legal restrictions. If a tree is protected by a Preservation Order, GOV.UK guidance states that cutting roots is treated as a prohibited activity requiring the local planning authority’s consent, unless an exception applies.
Before cutting roots, check whether the tree is protected and get professional advice. Our guide to Tree Preservation Order rules explains the basics for property owners.
For official guidance, see GOV.UK guidance on Preservation Orders and trees in conservation areas.
Practical Ways to Reduce Future Root Damage
Prevention starts with matching the right tree to the right place and maintaining both the tree and the property around it.
Practical steps include:
-
Choose suitable species and planting positions for the available space.
-
Keep drains, gutters and underground pipework in good condition.
-
Repair leaking drains rather than relying on repeated root cutting.
-
Avoid damaging major roots during landscaping or construction.
-
Use professional pruning where a plant genuinely needs size or structural management.
-
Monitor significant cracks or ground movement instead of assuming the cause.
-
Get advice before planting large trees close to buildings on shrinkable clay soils.
The RHS also recommends considering tree size, soil and foundations when planting near buildings. Its guidance on trees near buildings is a useful UK reference.
If you are planning new planting, M.A.C Tree Care can advise on species selection and positioning through our care services.
When Professional Advice Is Worthwhile
Call a professional when you need to understand the condition of the tree, whether tree work is justified, and which management option is proportionate.
Professional input is particularly useful when:
-
A mature tree stands close to a building showing new movement.
-
Major roots are exposed or have been damaged.
-
Roots are lifting paths or other surfaces.
-
A drain survey has identified root ingress.
-
You are considering significant pruning or removal.
-
It may be protected by a TPO or conservation area rules.
-
You are planning building work near established plants.

Making the Right Decision About Root Damage
The most useful rule is simple. Do not diagnose the problem from the presence alone.
Most trees near buildings do not cause structural damage. Where problems do occur, the cause may involve soil type, foundations, drainage, weather, size, and root activity together.
Act on evidence. Investigate drainage faults, take structural movement seriously, check legal protections and seek the right professional advice before cutting roots or removing a mature tree.
That approach protects the property while avoiding unnecessary work to healthy trees.
