Storms can turn a healthy looking tree into a serious hazard in minutes, especially when high winds, saturated ground, or flying debris damage the crown, trunk, or root plate. This checklist explains what to look for, what to do first, and the clear warning signs that mean it is time to stop inspecting and call an emergency tree surgeon.
Why post storm checks matter
Some storm damage is obvious, like a fallen tree or a snapped limb in the driveway. Other damage is hidden, such as cracks in the trunk, loosened roots, or branches hanging up in the canopy that can drop later without warning. Even if everything looks calm after the weather passes, delayed failure is possible, so a careful, safety first check is worthwhile.
First priority: keep people safe
Before looking closely at any tree, treat the area like a hazard zone. Wind damaged trees can be unstable, and attempting cutting or pulling can make the situation worse.
Do this first
- Keep children and pets indoors and away from the garden area where trees or large branches could fall.
- Stay well clear of any tree that is leaning, cracked, or has hanging branches lodged in the crown.
- If a tree or branch is touching power lines, do not approach it and contact the appropriate emergency service or network operator.
- If a tree is blocking a road or public right of way, avoid moving it yourself and report it to the relevant authority.
If there is any doubt about safety, the correct step is to stop and call a professional rather than taking risks with ladders or chainsaws.
Quick storm damage checklist
Walk the site from a safe distance first and scan for the common signs of a compromised tree. The points below are the same issues professional arborists prioritise because they indicate structural weakness and potential failure.
1) Fallen trees or major limbs on the ground
If a tree has already failed, there may be further hazards such as hung up branches, torn fibres, or partially attached limbs still in the canopy. A fallen tree can also be under tension where branches are pinned, creating unpredictable movement if disturbed.
2) Hanging branches and debris trapped in the crown
Branches that are broken but still attached or lodged are especially dangerous because they can fall at any moment. This is one of the most common reasons to call emergency tree services after storms.
3) New lean or unusual tilt
A tree that suddenly leans, even slightly, may have suffered root plate movement or trunk cracking. Leaning and uprooting are repeatedly highlighted as key indicators of storm related stress and risk.
4) Soil heave or root plate movement
Look at the ground around the base from a safe distance, especially on the windward side. Soil movement around the base in strong winds is listed as a warning sign of an unsafe tree.
5) Cracks, splits, and fresh wounds
Cracks that extend into the wood can indicate that a trunk or major limb has separated and lost strength. Splits or cracks in the trunk or branches are also listed as key signs to look out for in an unsafe tree.
6) Co dominant stems and weak unions under stress
Storms often exploit weak attachment points, especially where multiple stems or large branches meet. Post storm checks commonly focus on these unions because failure can involve heavy sections falling from height.
7) Damage near buildings, fences, and access routes
If branches have struck roofs, sheds, garages, fences, or are overhanging driveways and footpaths, treat it as urgent. These situations combine structural risk with public safety and property damage.
8) Signs of decay and fungal indicators
Cavities, decay, and fungi on bark or around the base can indicate weakening that increases storm failure risk. Councils also list rotting sections and fungi growth on bark, wood, or around the base as signs to look for in an unsafe tree.
When to call emergency tree surgeons immediately
If any of the following applies, it is time to stop assessing and request urgent help. These are high risk scenarios where failure can be sudden and consequences are severe.
Call immediately if
- A tree has fallen or is leaning dangerously after a storm.
- A large branch is hanging loose or lodged in the canopy and could fall.
- The tree has damaged, or is likely to damage, a roof, fence, shed, garage, or vehicle.
- The tree is blocking access such as a driveway, a road, or a public route.
- The tree is in contact with power lines or close enough that movement could bring it into contact.
- There are visible trunk splits, major cracks, or obvious root plate movement.
If any of these are present, keep clear and do not attempt to cut branches down from ladders, pull them with vehicles, or use a chainsaw without training.
What to do while waiting for help
Safety and preventing further damage come first. The goal is to reduce exposure, not to fix the tree without the right equipment.
Practical steps that help
- Keep everyone out of the danger zone and cordon off the area if possible.
- Photograph damage from a safe distance for insurance and records.
- Move vehicles away from trees if it can be done safely.
- Avoid parking or standing under damaged crowns, even if nothing is falling at that moment.
Common mistakes to avoid after storms
Many injuries occur after the storm has passed, not during the worst wind. The most common errors involve underestimating tension, instability, and the risk of delayed branch drop.
Avoid these actions
- Do not cut hung up branches that are lodged in the canopy without professional rigging and control.
- Do not climb ladders to “tidy up” broken limbs.
- Do not pull fallen trees or limbs with ropes, winches, or vehicles unless trained to manage tension and compression forces.
- Do not assume a tree is safe because it is still standing, especially if it now leans or the soil has lifted.
What a professional emergency response typically involves
An emergency arborist visit usually focuses on making the site safe first, then planning any further work needed to restore the tree or remove it if it cannot be retained. That can include removing hanging branches, reducing weight in the canopy, or emergency removal where stability is compromised.
A professional assessment also considers whether damage is likely to worsen, and whether nearby targets like buildings, footpaths, and neighbouring gardens increase the urgency. This helps homeowners choose the right level of work rather than guessing.
Aftercare and monitoring in the days that follow
Even after urgent hazards are removed, monitoring is important because some problems show up later as the tree responds. Guidance commonly recommends watching for delayed symptoms such as leaf discolouration, dieback, or changes in stability in the weeks following storm damage.
If the tree was stressed, avoid rushing into heavy feeding and focus on appropriate aftercare and professional advice. Where significant structural damage is present, a follow up inspection can help decide whether pruning, bracing, or removal is the safest long term route.
If storm damage has left a tree leaning, cracked, or shedding large branches, treat it as urgent and get professional help to make the site safe. East Hants Arborists can provide clear advice and a detailed written quote so you can review the agreed work and cost before proceeding.
Storm Tree Safety – Frequently Asked Questions
When should a storm damaged tree be treated as an emergency?
If the tree is leaning more than usual, uprooted, split, or has large hanging branches, it should be treated as urgent because failure can be sudden. These are common indicators of a storm compromised tree that may need immediate professional action.
What are the most common hidden dangers after a storm?
Hanging branches lodged in the canopy and cracks in the trunk or unions can be easy to miss from the ground but can fail later without warning. Post storm guidance highlights that windblown trees can be unstable and dangerous to work around.
Is it safe to use a chainsaw or ladder to clear storm damage?
Post storm advice warns that working with fallen or damaged trees can be high risk because trees may be unstable and can crush or trap people. If there is significant damage or instability, professional help is the safer option.
What should I do if a tree or branch is touching overhead power lines?
Keep well away and treat lines as live, because electricity can be dangerous even without obvious signs. Many UK network operators advise calling 105 for faults and emergencies involving power lines and vegetation.
How can I tell if a tree’s roots have moved?
Warning signs include soil heave, lifted turf, exposed roots, or cracks in the soil around the base, especially after high winds or heavy rain. These are indicators that the tree’s anchorage may be compromised.
What does a “hung up” branch mean, and why is it dangerous?
A hung up branch is a broken limb that is still caught in the canopy or tangled in other branches. It is dangerous because it can drop unpredictably, sometimes days after the storm when conditions change.
Should I remove all broken branches straight away?
Not always, because over pruning can add stress and inexperienced cutting around storm damaged wood can be dangerous. A staged approach that prioritises immediate hazards first is often recommended.
Who is responsible for a dangerous tree on private property?
Local authority guidance typically states that tree owners are responsible for maintaining trees on their land and managing safety risks. If the tree threatens a public area or highway, reporting routes may differ depending on location.
Can a tree look fine but still be unsafe after a storm?
Yes, because internal cracking, weakened unions, and partially failed roots are not always obvious without a proper inspection. Post storm checks are important because some risks only become apparent after the weather clears.
What information should I provide when calling an emergency tree surgeon?
Share what has happened, what the tree is affecting (house, road, driveway, footpath), and whether there are hanging branches, a new lean, or root plate movement. Taking photos from a safe distance can help communicate severity without approaching the hazard zone.
