High winds and storms are one of the most common causes of tree-related damage in the UK. While healthy, well-maintained trees can usually withstand severe weather, weakened or neglected trees can quickly become a serious safety risk. Falling branches, uprooted trees, and structural failures can cause damage to property, vehicles, and even put lives at risk.
Understanding how to spot the warning signs of a dangerous tree, especially before or after storms, can help you take action early and avoid costly or hazardous situations.
Why storms make trees dangerous
Strong winds place enormous pressure on a tree’s structure. When combined with heavy rain that softens the ground, this pressure can lead to trees leaning, splitting, or uprooting altogether. Trees that already have hidden weaknesses are particularly vulnerable during storms.
Problems such as decay, poor root anchorage, previous pruning damage, or disease may not always be obvious in calm conditions, but high winds often expose these weaknesses suddenly and dramatically.
Visible signs of a dangerous tree
There are several warning signs that may indicate a tree is unsafe during high winds:
Dead or hanging branches – Often referred to as “deadwood,” these can snap off easily and fall without warning.
Cracks or splits in the trunk – Vertical cracks, especially those that deepen after a storm, suggest structural weakness.
Leaning trees – A slight lean isn’t always a problem, but a sudden change in angle or exposed roots is a serious concern.
Fungal growth at the base – Mushrooms or fungal brackets can indicate internal decay, reducing the tree’s strength.
Sparse or dying canopy – Trees that fail to leaf properly or show extensive dieback may already be under stress.
If you notice any of these signs, particularly after a storm, it’s important to seek professional advice as soon as possible.
Root problems and soil conditions
A tree’s stability depends heavily on its root system. During prolonged wet weather, saturated soil can lose its ability to hold roots firmly in place. This is especially common in clay-heavy soils.
Warning signs of root failure include lifted turf around the base, visible roots, or cracks forming in the ground. These symptoms suggest the tree may be at risk of uprooting during the next strong gust of wind.
Trees close to buildings and roads
Trees growing near houses, sheds, fences, or roads require particular attention. Even healthy trees can pose a risk if large branches overhang roofs or public areas.
Regular inspections and preventative pruning can reduce wind resistance by thinning dense canopies and removing weak limbs. This proactive approach significantly lowers the chance of storm damage while preserving the tree’s health and appearance.
After a storm: what to check
Once severe weather has passed, it’s wise to inspect your trees carefully. Look for broken branches caught in the canopy, fresh cracks, or sudden changes in posture. Avoid attempting to remove damaged branches yourself — storm-damaged trees are unpredictable, and working at height with unstable limbs is extremely dangerous without the proper training and equipment.
When to call a professional tree surgeon
If you’re unsure about the condition of a tree, it’s always safer to consult a qualified tree surgeon. Professionals can assess structural integrity, identify hidden decay, and recommend appropriate action, whether that’s pruning, cable bracing, or, in some cases, removal.
Emergency tree surgery may be required if a tree poses an immediate risk to people or property. Acting quickly can prevent further damage and reduce long-term costs.
Prevention is better than emergency call-outs
The best way to manage storm-related tree risks is through regular maintenance. Routine inspections, pruning, and early intervention help ensure trees remain strong and resilient throughout the year.
By addressing potential issues before storms arrive, you protect not only your property but also the long-term health of your trees.
High winds and storms can turn unnoticed tree weaknesses into serious hazards. Knowing what to look for, and when to seek professional help, is essential for keeping your outdoor spaces safe.
