Introduction
It’s no secret that trees enhance the look and value of a property. In areas like Great Shelford and across Cambridge, mature trees bring character and natural beauty to homes and gardens. But while their presence is welcome, overhanging branches can quietly pose a serious threat to your roof if left unchecked.
Many homeowners only notice the issue when damage has already occurred. At Great Shelford Tree Surgeons, we believe prevention is far more cost-effective than repair. So let’s explore how branches impact roofs—and why professional tree care makes a real difference.
How Tree Branches Can Damage Roofs
Physical Contact and Abrasion
Even gentle brushing from branches during wind or storms can wear away roofing materials over time. Shingles, tiles, and flashing are all vulnerable to repeated friction, eventually leading to leaks or structural weaknesses.
Impact Damage from Falling Limbs
Dead or weak branches can fall unexpectedly, especially during bad weather. A single heavy limb can puncture the roof, damage gutters, or dislodge tiles—posing a risk not just to the building, but also to the people living inside it.
Moisture and Moss Build-Up
Overhanging branches provide excessive shade and restrict airflow, keeping the roof damp. This creates ideal conditions for moss, mould, and mildew, which can degrade materials and clog gutters—leading to water ingress and interior damage.
Pest Pathways
Branches too close to the roof act like bridges for squirrels, rats, and insects. These pests can gnaw through roofing material or nest in loft spaces, causing additional and often hidden damage.
Gutter Blockage and Overflow
Leaves and twigs from overhanging branches can quickly clog gutters, especially in autumn. Blocked gutters overflow, sending water down walls or backing it up under the roofline, which leads to rot and water stains inside the home.
Signs That Branches Are a Risk
- Scratches or visible wear on roof tiles
- Accumulation of leaves or debris in gutters
- Damp patches on ceilings after rain
- Moss growth on shaded roof areas
- Sounds of rubbing or scraping during wind
What You Can Do
- Trim Overhanging Branches: Regular pruning keeps branches well away from the roof. Aim for a minimum clearance of 1–2 metres.
- Schedule Tree Inspections: A professional can assess tree health, stability, and growth patterns.
- Remove Dead Wood: Prompt removal of weak or dead limbs reduces the risk of unexpected falls.
- Keep Gutters Clean: Especially during autumn, regular clearing of debris prevents overflow and roof deterioration.
