Quick answer: After a storm, check from ground level for missing tiles, debris in the garden, sagging guttering, and lifted flashing, and check inside for new damp patches or musty smells in the loft. Avoid climbing onto the roof yourself. A drone survey or professional inspection can safely confirm the damage and provide evidence for an insurance claim.
High winds, heavy rain, and sudden temperature swings all take a toll on UK roofs, and the damage is not always obvious straight after a storm passes. A tile can shift just enough to let water in without falling off completely, and flashing can lift at the edge without being visible from the ground. Knowing what to look for, and how to check safely, can be the difference between a small repair and a much larger internal water damage problem weeks later.
This guide walks through what to check after severe weather, the warning signs that point to hidden damage, and when it is time to call a professional rather than get up on the roof yourself.
Why UK Weather Is Particularly Hard on Roofs
The UK does not experience the extreme heat or seismic activity that drives roof design in some other countries, but its weather pattern creates its own unique stresses. Roofs are regularly exposed to strong, gusting winds, especially in coastal and elevated areas, combined with persistent rainfall that gives water every opportunity to find a way in through even a small gap.
Freeze thaw cycles, where moisture trapped in small cracks freezes and expands during cold snaps, then thaws again, gradually widen existing weaknesses over successive winters. This means storm damage is rarely an isolated event. It is often the final failure point of wear that has been building for years, triggered by one particularly strong gust or heavy downpour.
What to Check From the Ground After a Storm
Before considering any closer inspection, a careful look from ground level, or from an upstairs window with a clear view of the roof, can reveal several common issues.
Missing or Displaced Tiles
Look for gaps in the tile pattern, or tiles that appear to be sitting at a different angle to those around them. A single displaced tile is often the first visible sign that wind has lifted the roof covering.
Debris in the Garden or Guttering
Fragments of tile, slate, or ridge cement found in the garden or blocking guttering are a clear indicator that something has come loose from the roof, even if you cannot immediately see where from.
Sagging or Detached Guttering
Guttering pulled away from the fascia, hanging at an odd angle, or overflowing during rain despite not being blocked with leaves usually points to storm related stress on the fixings.
Visible Damage to Chimneys or Aerials
Chimney stacks and aerials act as tall, exposed points that catch more wind load than the surrounding roof. Cracked pointing, leaning stacks, or a dislodged aerial bracket are worth noting for a closer inspection.
Flashing Lifted at Roof Junctions
Flashing around chimneys, dormer windows, and roof valleys is designed to sit tight against the surface below it. Any visible gap, curling edge, or flashing that appears to be flapping in wind is a sign it may no longer be sealing properly.
Signs of Hidden Storm Damage Inside the Property
Not all storm damage is visible from outside, and some of the clearest evidence shows up inside the home in the days following bad weather.
New Damp Patches on Ceilings
A patch that was not there before a storm, particularly one that grows or darkens after subsequent rain, strongly suggests water is entering through a new gap in the roof covering. Our guide to tracing a roof leak back to its source explains why the stain rarely sits directly beneath the actual entry point.
Musty Smells in the Loft
Even before visible staining appears, a sudden musty or damp smell when opening the loft hatch can indicate moisture has started collecting in the roof space.
Water Stains Around Chimney Breasts
Because chimneys are common failure points for flashing, water stains appearing on walls or ceilings near a chimney breast after a storm are a common and specific warning sign worth acting on quickly.
Drips or Active Leaks During Heavy Rain
An active drip during rainfall is the clearest possible sign of a breach, and should be addressed as an emergency rather than left until the next dry spell, since ongoing water ingress accelerates timber and insulation damage significantly.
Why You Should Not Inspect Storm Damage From the Roof Yourself
It is tempting to grab a ladder and take a closer look immediately after noticing a problem, but roof surfaces are significantly more dangerous after storms than they appear. Wet tiles are slippery even when dry weather has returned, loose debris can shift underfoot without warning, and any damage already present may not be able to bear normal foot traffic safely.
A drone roof survey offers a far safer alternative, capturing detailed images of the entire roof surface without anyone needing to climb up. This is particularly useful immediately after a storm, since it creates a clear, dated record of the damage that can support an insurance claim, something we cover in detail in our guide to drone roof surveys.
Making an Insurance Claim for Storm Roof Damage
Most UK home insurance policies cover storm damage as standard, though the exact definition of a qualifying storm varies between insurers, typically requiring wind speeds above a certain threshold recorded for the area at the relevant time.
To support a claim effectively, gather dated photographs of the damage as soon as safely possible, note the date and approximate time the damage occurred if known, and avoid making permanent repairs before the insurer has had a chance to assess the damage, beyond temporary measures needed to prevent further water ingress such as a tarpaulin over an exposed section.
A written report from a qualified roofer, ideally supported by drone survey imagery, gives insurers clear, professional evidence of both the extent of the damage and that it resulted from the storm event rather than gradual wear, which can otherwise complicate a claim.
Emergency Steps If Water Is Actively Entering Your Home
If you notice active water ingress during or immediately after a storm, moving quickly can limit the extent of the damage considerably. Place a container beneath any drip to protect flooring and furnishings, and if a ceiling shows signs of bulging from trapped water, carefully puncturing a small hole to release the water in a controlled way can prevent a larger, uncontrolled ceiling collapse, though this should only be done if it can be done safely and the area beneath is protected.
Moving furniture and valuable items away from the affected area reduces the risk of further damage while you arrange for an emergency inspection. A temporary tarpaulin, fitted by a professional wherever possible rather than attempted without the right equipment, can prevent further water entry until permanent repairs are scheduled.
Preventing Future Storm Damage
While no roof can be made entirely storm proof, regular maintenance significantly reduces vulnerability. Keeping guttering clear allows water to drain properly during heavy rain rather than backing up under the roof edge. Checking and maintaining fascias and soffits, which we cover in our dedicated fascia and soffit guide, ensures the roofline itself is not already weakened before the next storm arrives.
Periodic roof inspections, whether a physical check or a drone survey, catch loose tiles and deteriorating flashing before they become the point of failure during the next spell of severe weather. Trees overhanging the roof should also be kept trimmed, since falling branches during high winds are a common and entirely preventable cause of significant roof damage.
Flat Roofs and Storm Damage
Flat roofs face a different set of storm risks compared with pitched roofs, covered in full in our flat roof maintenance guide. Rather than shedding water quickly down a slope, flat roof surfaces rely on a membrane and a slight fall towards drainage outlets to clear rainwater. High winds can lift the edge of a membrane if it has started to come loose, and heavy rainfall combined with a blocked outlet can lead to ponding, where standing water sits on the roof for extended periods, placing additional weight and pressure on the surface.
After a storm, flat roofs should be checked specifically for lifted edges or seams, visible ponding that has not drained within a day or two of rain stopping, and any blistering or cracking in the membrane surface, which often becomes more visible once wet.
Seasonal Patterns in Storm Roof Damage
Storm damage in the UK tends to cluster around specific periods each year, which is useful context when planning maintenance. Late autumn through winter brings the most frequent and severe named storms, often combining high winds with heavy, sustained rainfall. Spring can bring its own risks in the form of sudden hail, which can crack older or already weakened tiles even without high winds involved.
Scheduling a roof inspection in early autumn, before the most active storm season begins, gives time to address any developing weaknesses while conditions are still favourable for repair work, rather than discovering a problem mid storm when access and materials are harder to arrange quickly.
When to Call a Professional
Any of the following situations warrant a professional inspection rather than a wait and see approach: an active leak during or after rain, visible tile or slate damage from the ground, sagging or significantly displaced guttering, cracked or leaning chimney stacks, or any new damp patch appearing on an internal ceiling or wall.
Acting promptly after storm damage is identified, even if the damage looks minor, prevents small issues from developing into structural repairs. A roof that has let in water for a few days during one storm is a repair. The same roof left unaddressed through several subsequent storms can become a much larger and more expensive structural problem.
Working With Neighbours and Shared Roofs
On semi detached or terraced properties, storm damage does not always respect boundary lines. A dislodged tile from a neighbouring roof can land on yours, and shared guttering runs may need coordinated repair even if only one household reports a visible problem. Where damage appears to originate from or affect a shared structure, it is worth having a conversation with neighbours early, since insurers on both sides may need to be involved and a single contractor addressing the full affected area is often more efficient and cost effective than two separate repairs carried out independently.
Frequently Asked Questions
How soon after a storm should I get my roof checked?
Ideally within a few days, and sooner if you notice any signs of active leaking, visible damage, or debris on the ground. Prompt inspection also strengthens any insurance claim by clearly linking the damage to the specific storm event.
Will my insurance cover storm damage to my roof?
Most standard UK home insurance policies cover storm damage, though the definition of a qualifying storm and any excess payable varies by insurer. Checking your specific policy wording is worth doing as part of the claims process.
Can a few missing tiles really cause serious damage?
Yes. Even a small gap allows sustained water ingress during rain, which can saturate roof timbers and insulation over time, leading to rot, mould, and internal damage that costs significantly more to fix than the original tile replacement would have.
Is it safe to inspect my own roof after a storm?
Climbing onto a roof after storm damage carries higher risk than normal, due to loose debris, weakened areas, and slippery surfaces. A ground level check combined with a professional inspection, or a drone survey, is the safer approach.
How do I know if damage was caused by a specific storm or general wear?
A professional inspection can often distinguish between sudden storm damage, such as a cleanly displaced tile, and gradual wear, such as worn out flashing that finally failed under storm conditions. This distinction can matter for insurance purposes.
Documenting Damage the Right Way
If you do need to make an insurance claim, the quality of your documentation directly affects how smoothly the process goes. Photograph the damage from multiple angles, including a wider shot that shows the location on the roof and closer shots of the specific defect. Where possible, include something in the frame for scale, such as a ruler or a common object, so the size of the damage is clear from the image alone.
Keep a simple written record alongside the photographs, noting the date the damage was noticed, the date and nature of the storm believed to have caused it, and any temporary measures taken to prevent further water ingress. This record, combined with a professional assessment report, gives insurers everything needed to process a claim without unnecessary back and forth.
Storm Response Across London, Surrey and the South East
Exposed rural and elevated parts of Surrey and the South East tend to see the highest wind speeds during named storms, while dense London terraces more often report debris damage from shared chimney stacks and nearby scaffolding on neighbouring works. Nationwide Roof Professionals provides emergency storm damage inspections across London, Surrey, and the wider South East, with drone survey options available where fast, safe assessment is needed.
Acting Quickly Protects Your Home
Storm damage rarely announces itself clearly. A gap the width of a finger is enough to let significant water into a roof space over a period of sustained rain, and the resulting damage is almost always more expensive than the original repair would have been.
If you have experienced recent severe weather and want a clear, safe assessment of your roof’s condition, our team at Nationwide Roof Professionals can carry out a full inspection as part of our roofing services, including drone survey options where appropriate. Contact us today for a fast response and a clear plan to protect your home before the next storm arrives.
