Tree roots do more than anchor trees in the ground. They absorb water, store nutrients and help trees remain stable. However, they can also affect buildings, driveways and drainage systems if not managed correctly. Knowing how tree roots grow and interact with their surroundings is key to preventing damage and keeping your trees healthy.
In this guide, we’ll cover the basics of tree root systems, common problems they cause and how a tree surgeon in Leicester can help protect your property.

How Tree Root Systems Work
Tree roots extend far beyond what most people expect. While the trunk and branches are visible, the root system spreads underground, often reaching two to three times the width of the tree canopy. There are two main types of tree roots:
- Structural Roots – Thick, woody roots that provide stability and anchor the tree in place.
- Feeder Roots – Thin, fibrous roots responsible for absorbing water and nutrients from the soil.
Most tree roots grow within the top 60cm of soil, making them more likely to interfere with hard surfaces and underground utilities. While they generally spread outward rather than downward, certain conditions—such as compacted soil or poor drainage—can influence root growth patterns.
How Tree Roots Affect Your Property
1. Damage to Foundations and Driveways
Tree roots naturally seek moisture, which can lead them toward building foundations and paved surfaces. While they don’t break through solid concrete, they can grow into existing cracks and widen them over time. This often causes:
- Uneven driveways and footpaths.
- Cracks in walls and foundations.
- Structural shifts due to soil displacement.
If you notice cracks forming near a tree, it’s important to have the roots assessed by a tree surgeon in Leicester before the problem worsens.
2. Blocked Drains and Pipes
Underground pipes can attract tree roots, especially if they have small leaks. Roots enter through gaps in pipes and expand, leading to blockages or even pipe damage. Signs of root intrusion in drains include:
- Slow-draining sinks and toilets.
- Frequent blockages in your drainage system.
- Unpleasant odours coming from outdoor drains.
Regular maintenance and early detection can prevent costly repairs. A professional tree surgeon can advise on whether root pruning or tree removal is necessary.
3. Soil Drying and Subsidence
Trees absorb large amounts of water, which can lead to soil shrinkage—especially in clay-heavy areas. As the soil dries out, it contracts, potentially causing subsidence, where the ground beneath buildings or pavements sinks unevenly.
Common signs of subsidence include:
- Cracks appearing in walls or floors.
- Doors and windows become misaligned.
- Sudden dips in outdoor surfaces.
If a tree is causing subsidence, a tree surgeon in Leicester can assess whether reducing the tree’s water intake or removing it altogether is the best course of action.
4. Root Spread into Gardens and Lawns
Tree roots can compete with other plants for water and nutrients, leading to patchy grass, stunted growth or bare areas in the garden. Some species are more aggressive than others, with fast-growing trees such as willows, poplars and oaks known for spreading wide root networks.
Solutions for managing root spread include:
- Installing root barriers to direct growth away from sensitive areas.
- Regular root pruning to control expansion.
- Choosing trees with non-invasive root systems if planting near structures.
How to Prevent Root-Related Issues
1. Plant Trees at a Safe Distance
When planting new trees, consider their mature size and root spread. A tree surgeon in Leicester can recommend suitable species for urban and residential settings. General guidelines include:
- Small trees: At least 3 metres from structures.
- Medium trees: At least 6 metres from structures.
- Large trees: At least 10 metres from structures.
2. Install Root Barriers
Root barriers are underground barriers designed to redirect roots away from buildings and drainage systems. They are particularly useful when planting trees close to structures.
3. Regular Tree Maintenance
Routine inspections by a professional tree surgeon in Leicester help detect root problems early. Pruning and managing root growth prevent long-term damage to property and nearby structures.
When to Call a Tree Surgeon
Some root-related issues require professional intervention. If you notice any of the following, it’s best to contact a tree specialist:
- Trees leaning or showing signs of instability.
- Cracks in walls, driveways or pavements near tree roots.
- Slow-draining pipes with suspected root intrusion.
- Uneven ground or soil movement around trees.
- Concerns about tree placement and future growth.
A tree surgeon in Leicester can assess the situation, recommend solutions and carry out necessary work such as root pruning, tree removal or installing barriers.
Managing Tree Roots Effectively
Tree roots are essential for tree health but they can also cause unexpected problems if not monitored properly. Understanding how roots grow and interact with their surroundings helps prevent damage to buildings, drainage systems and garden landscapes.
