Introduction
Trees bring a great deal of beauty, shade, and environmental benefit to our homes and gardens — especially in the leafy surroundings of Haslemere. However, when trees are left unmanaged, they can slowly begin to cause structural damage that goes unnoticed until costly repairs are needed.
At LM Tree Surgery Haslemere, we often help property owners identify and resolve problems caused by trees. Many of these issues could be avoided with proactive care and early intervention. Here are seven structural concerns every homeowner should watch out for.
1. Root Damage to Foundations
Tree roots are stronger and more persistent than many people realise. They can spread several metres in search of water, and if your home’s foundations are nearby, they may exploit even the smallest cracks or weaknesses.
Possible consequences include:
- Cracked foundations or footings
- Uneven floors and walls indoors
- Long-term instability in older buildings
2. Uplift of Paving and Driveways
As tree roots expand, they often push upwards against paths, patios, and driveways. This creates tripping hazards and unsightly gaps or tilting — particularly with tarmac or block paving installations.
Look out for:
- Raised slabs or edges
- Visible cracks or lifting around the base of trees
- Water pooling in distorted areas
3. Damage to Roofing and Gutters
Branches that overhang roofs can scrape tiles, clog gutters with leaves, and drop heavy limbs during storms. Over time, this leads to broken tiles, damp ingress, and guttering that no longer drains properly.
Regular pruning helps to:
- Prevent roof tile damage
- Reduce blocked gutters and downpipes
- Lower the risk of storm-related accidents
4. Subsidence Issues in Clay Soil
In areas with clay-rich soil — common across parts of Surrey — large trees can contribute to soil shrinkage, especially in dry periods. This may cause subsidence, cracking external walls, or doors and windows that no longer close properly.
Key signs:
- Cracks around windows or doors
- Uneven flooring or internal gaps
- Worsening during dry weather spells
5. Interference With Boundary Walls and Fences
As trees grow, their roots and trunks can press against garden walls or fences, pushing them out of line or even causing collapse. This is particularly problematic when planting trees too close to boundaries.
Prevention includes:
- Careful positioning of young trees
- Professional pruning to control growth
- Early root management when trees are immature
6. Encroachment on Underground Utilities
Tree roots don’t just cause surface problems — they can grow into underground pipes, especially if there are existing cracks or moisture. Blocked or damaged drains can lead to major disruption.
Risk areas include:
- Sewer pipes
- Water mains
- Irrigation systems
7. Excess Shade and Moisture Retention
Large, dense tree canopies can block sunlight and airflow, creating damp conditions near buildings. This encourages moss and algae growth, particularly on north-facing walls, and may contribute to faster wear of exterior surfaces.
Solutions include:
- Crown thinning to improve light access
- Pruning to reduce overhang
- Regular checks near shaded walls or roofs
