Storm damage can have wide-ranging and often unexpected effects. A tree can take a hit in high winds, look stable the next morning, then fail days or weeks later when the ground softens, the canopy dries, or a hidden crack spreads. If that tree sits near a footpath, car park, access road or building, the risk is not just to property. It is to people, operations and your ability to show you acted responsibly.
The good news is that most incidents are preventable with early, proportionate action. Below, we’ll break down what to look for, what to do in the first 24 to 72 hours, and how to move from urgent make-safe work to planned inspections and remedial tree management across Preston, Lancashire and the wider North West.
After a storm, the most dangerous defects are often the ones you cannot see from a quick glance. Wind loading can weaken unions, shift root plates and leave branches “hung up” in the canopy, ready to drop with the next gust or heavy rain. That’s why bringing in competent tree surgeons early can be the difference between a controlled solution and an unplanned emergency.
Some warning signs are obvious. Others are subtle but high-risk:
If you spot any of these, treat the area as a potential failure zone. A tree that has partially failed can be more unpredictable than one that has fully come down.
Even minor defects become major problems if the tree is in the wrong place. Prioritise checks around:
A useful rule of thumb is simple: the more people pass through, and the more valuable the nearby assets, the faster you should act.
After a storm, the expectation is not perfection. It is reasonable, risk-based management that shows you took practical steps to keep people safe. The HSE endorses a sensible, proportionate approach to managing the risk from falling trees and branches, and points tree owners and managers towards National Tree Safety Group (NTSG) guidance as a benchmark for “reasonable and balanced” practice.
That matters because tree failures can be catastrophic. The NTSG’s national fatality record shows 139 public fatalities from falling or fallen trees between 1997 and mid-October 2025, averaging around 4.7 per year. Even though the overall risk is low in day-to-day terms, a storm can raise it sharply in specific locations, especially where access and occupancy are high.
A good post-storm response usually includes:
If you already know there are overdue issues on site, storms tend to turn “manageable defects” into urgent hazards. That’s why neglecting a tree on a commercial property can quickly become expensive, disruptive, and far harder to defend after the fact.
When the weather clears, the pressure is often to “get things back to normal” quickly. But storm-damaged trees can fail without warning, especially where branches are hung up, trunks are cracked, or roots have shifted. The priority in the first 24 to 72 hours is simple: reduce exposure, then get competent eyes on the problem.
Start with practical controls that protect people while assessments and works are arranged.
If a tree is near a boundary, make sure the controls extend far enough. A large limb can travel and bounce, and root plates can shift further after heavy rain.
Storm response is one of the easiest times for well-meaning people to get hurt. A few hard rules help keep everyone safe:
If teams need to keep operating on site, keep the approach strict. Temporary disruption is better than a preventable incident.
Some situations can be managed with short-term controls and a scheduled visit. Others should be treated as urgent because the consequences are high or failure risk is immediate.
Treat it as emergency work if you have:
In these cases, the safest course is rapid safety works by a competent contractor with the right equipment and method statements. Great Oaks provides emergency tree response and remedial works across Preston, Lancashire and the wider North West, with the capacity to secure the area, remove immediate hazards, and leave the site stable for follow-on works.
A short record protects you as much as it informs the next step. Keep it simple:
This also helps speed up response. The more clearly you can describe what’s happened, the easier it is to prioritise resources and arrive with the right kit.
Emergency work is about removing immediate danger. The smarter long-term win is what happens next: a clear, prioritised plan that reduces repeat call-outs, limits disruption, and keeps budgets predictable.
Once urgent hazards are dealt with, the next step is a clear, prioritised plan that reduces repeat call-outs, limits disruption, and keeps budgets predictable.
In practice, that usually means:
This is also where risk-based thinking helps you avoid unnecessary intervention. NTSG guidance highlights that the overall risk from trees is generally very low, so actions should be proportionate to site use and the consequences of failure.
Storm damage often creates defects that worsen over time. Acting early can mean a smaller, safer job rather than a complex emergency later. Depending on what we find, remedial works can include:
These are exactly the kinds of responsive and planned solutions we deliver through our commercial tree services across Preston, Lancashire and the North West.
Storms expose weak points, but routine upkeep reduces how often those weak points become incidents. Folding tree inspections and cyclic works into grounds maintenance programmes helps you stay ahead of seasonal risk, especially on busy sites where access and presentation matter year-round.
Storm response can feel urgent, but speed is only useful when it is matched with control. Damaged trees create complex hazards: timber under tension, unstable root plates, unpredictable hangers, and work that often happens close to buildings, public routes, parked vehicles and live infrastructure. That is exactly when competence and auditability matter most.
If you are arranging works on a managed site, you need more than a quote. You need confidence that the contractor’s systems, people and on-site practices stand up to scrutiny.
The ARB Approved Contractor scheme is run by the Arboricultural Association and is widely recognised as a benchmark for professional tree work, with contractors assessed and expected to continue meeting defined standards for quality, safety and professional conduct. Choosing an ARB Approved Contractor like Great Oaks helps demonstrate that the people on your site are working to a verified standard.
For many sites, the practical challenge is not only getting the work done, but doing it in a way that aligns with wider compliance requirements. That might include contractor onboarding, permit controls, RAMS, and the level of evidence expected after an incident or near miss.
Great Oaks sets out our approach clearly through our accreditations, including ARB Approved Contractor status, Constructionline Gold, ROSPA membership, Once For All (SSIP) accreditation. This gives you a stronger foundation when you need to show due diligence, especially after storm damage when decisions are rightly examined more closely.
Accreditations are only part of the picture. The on-site difference usually comes down to:
Most storm incidents are not caused by “one bad night of weather” alone. They’re usually the result of wind loading plus existing weaknesses, made worse by saturated ground, previous pruning history, pests or disease, and repeated exposure in open sites. Forest Research notes that wind damage can be severe at scale, with major storms damaging over 1 million m³ of timber at least five times in the last 50 years, which is a useful reminder of how much force storms can generate even before you factor in local site conditions.
A storm-readiness plan helps you respond faster, reduce emergency work, and keep access open more reliably across the year.
A practical approach is to focus effort where failure would have consequences, rather than treating the entire site the same way.
Prioritise trees near:
Then plan cyclic work around:
This is where planned programmes support day-to-day presentation while also reducing avoidable safety issues.
Instead of relying on ad-hoc checks, set triggers that prompt faster inspection.
Use a short post-storm inspection when any of these occur:
This keeps decisions consistent, especially when multiple teams are involved.
Documentation does not need to be complicated. It needs to be repeatable and easy to file.
A one-page log is often enough:
If you need support moving from reactive call-outs to a steadier plan, Great Oaks can carry out inspections and deliver programmed remedial works through our commercial tree services, with emergency response available when storms create urgent hazards.
How can you tell if a tree is dangerous after a storm?
Start by looking for changes. Storm damage often shows up as new movement, fresh cracking, or debris that wasn’t there before.
Act quickly if you see:
If anything looks uncertain, it’s safer to restrict access and arrange a professional inspection rather than waiting for the next windy day.
Should the area be closed straight away?
If there’s any realistic chance of failure where people or vehicles pass through, yes. Temporary barriers and reroutes are usually the fastest way to reduce risk while you arrange attendance. The Health and Safety Executive promotes a sensible, proportionate approach to tree risk management, which supports practical controls that match the level of risk.
Can you deal with a storm-damaged tree if it has a TPO or is in a conservation area?
Often, yes, but the route depends on the urgency and the local planning controls. Where there’s an immediate danger, there are typically options to carry out necessary work, with the right evidence and notifications. The key is to document the defect clearly (photos help) and use a competent contractor who can advise on the correct process and keep records in order.
How quickly should storm-damaged trees be inspected?
As a rule, sooner is better for trees near access routes, entrances, car parks and buildings. A tree can be destabilised by wind and then worsen after rainfall, freeze-thaw cycles, or follow-on gusts. If you have multiple areas to check, prioritise higher-occupancy zones first and work outwards.
Do you clear everything and leave the area usable again?
That is usually the aim. For emergency and remedial works, it’s normal to:
What records should be kept for compliance and insurance purposes?
Keep it light but consistent. A simple record usually covers:
If a tree has failed, is leaning, or has damaged limbs over public routes, vehicles or buildings, treat it as urgent. Storm-damaged trees can deteriorate quickly, especially as the ground softens and follow-on winds arrive.
