Why is my VELUX window rattling when it's windy?
A VELUX roof window that rattles during windy weather can be unsettling, particularly if the noise has only recently started. The cause could be something relatively simple, but it is important to establish which part is moving.
Roof windows are exposed to the weather more directly than many vertical windows. During strong winds, they can experience pressure changes and vibration, particularly on exposed roofs.
However, a VELUX window that has suddenly started rattling should not automatically be dismissed as normal. The important question is whether the noise comes from the window itself, one of its operating components or something associated with the surrounding roof.
What causes a VELUX window to rattle?
Rattling usually involves a component moving or vibrating. Wind may make that movement noticeable, even if the underlying issue has developed gradually over time.
Possible causes include:
- A loose or worn operating component
- A sash that is not closing or securing correctly
- Wear within hinges or other moving parts
- A loose blind or accessory
- Movement around external covers or fittings
- Age-related deterioration
- Vibration from a nearby part of the roof
Not every rattling noise indicates a serious problem. Equally, some faults are worth addressing promptly, especially if the window no longer closes securely.
Has the noise only recently started?
A change in how your roof window sounds can be useful information. If it was previously quiet during similar weather and now rattles regularly, something may have changed in the window or surrounding installation.
Could the window sash be moving in the wind?
The sash is the opening part of the roof window. When closed correctly, it should sit in its intended position within the frame.
If the sash is not securing as it should, wind pressure may make movement or vibration more noticeable.
This can sometimes be accompanied by a draught, a change in the way the window closes or an unusual sound when the locking mechanism is operated.
Look out for:
- The window no longer closing as smoothly as before
- The handle or control bar feeling different
- Visible movement when the window should be closed
- A new gap around part of the sash
- Rattling accompanied by whistling or cold air
If the window cannot be closed securely, arrange an inspection rather than continuing to force the mechanism.
Can worn hinges cause a rattling noise?
Hinges and other moving components play an important role in the operation of a roof window.
Over time, components can wear or develop problems that affect how the sash moves or sits within the frame.
A rattling sound does not prove the hinges are faulty, but if the window has also become difficult to operate or feels unusually loose, the operating system deserves attention.
AR Windows provides specialist VELUX window repairs and can assess whether an operating fault is suitable for repair.
What if the control bar or handle is rattling?
Depending on the VELUX model, the window may use a top control bar, bottom handle or powered operating mechanism.
A loose component can sometimes make a noise when the wind causes vibration through the window.
If the handle or control bar has become loose, feels different or no longer operates correctly, the mechanism should be checked.
We have covered this in more detail in our guide to VELUX window handle replacement.
Could it actually be the VELUX blind?
Before assuming the roof window itself is faulty, consider whether the sound could be coming from a blind or accessory.
A blind, guide rail or other internal fitting may vibrate or make contact with another surface.
If it is safe and easy to do so, observe whether the noise changes when the blind is in a different position. Do not dismantle anything or interfere with the window mechanism.
Noise from inside
A blind, handle, control bar or another accessible internal component may be responsible.
Noise from outside
External covers, roof components or parts of the installation may need professional inspection.
Can external VELUX covers or flashings rattle?
Roof windows include external components designed to protect the installation from the weather.
If a fitting becomes loose or damaged, wind may cause movement or vibration. However, the noise could also come from nearby roof tiles, roofing materials or another part of the surrounding construction.
It is important not to assume that the window itself is responsible simply because the sound appears to come from that area.
External inspection should be left to somebody with the appropriate equipment and experience. Do not climb onto the roof or lean outside the window to investigate.
Is some movement or noise normal in strong winds?
Very strong winds can create pressure changes and noise around a roof. The surrounding roof covering, ventilation features and other fittings may all contribute.
A little noise during extreme weather is not necessarily evidence of a defect.
However, repeated metallic rattling, visible movement, a change in closing behaviour or a noise that is becoming progressively worse should not simply be ignored.
What is the difference between rattling and whistling?
The type of noise can help narrow down the possibilities.
Rattling
Usually suggests that something is vibrating, moving or making repeated contact with another component.
Whistling
More commonly relates to air passing through a narrow opening, ventilation feature or gap.
These are general distinctions rather than definitive diagnoses. A roof window can also produce more than one type of noise.
For airflow-related sounds, see our article Why Is My VELUX Window Making a Whistling Noise?
Why does my VELUX window only rattle during certain winds?
Wind direction and strength can change how pressure is applied to a roof window and the surrounding roof.
A component may remain quiet in calm weather but begin vibrating when wind reaches it from a particular direction.
This does not necessarily mean the problem is minor. It simply means the conditions needed to produce the noise are not present all the time.
Can a rattling VELUX window let in rain?
Rattling does not automatically mean the window is leaking.
However, if the noise is associated with a sash that does not close correctly, damaged external components or another installation fault, the condition of the window should be investigated.
If you have also noticed water around the window, do not assume the cause is the same as the rattling.
Our article on VELUX window condensation or leaks explains why moisture problems need to be assessed separately.
Can I fix a rattling VELUX window myself?
The safest first step is observation rather than attempting a repair.
You may be able to identify whether an accessible blind or another internal accessory is making the sound. Beyond that, avoid tightening unknown fixings, removing covers or forcing operating components.
Some parts are involved in keeping the sash secure and the installation weatherproof. Incorrect adjustments can create additional problems.
Do not wedge the window to stop the noise
Packing gaps with paper, foam, timber or other materials may temporarily reduce rattling, but it can interfere with proper closing and hide the underlying fault.
What should I check before contacting AR Windows?
There are several useful observations you can make without dismantling the window or accessing the roof.
Try to establish:
- Whether the sound comes from inside or outside
- Whether it happens only during strong winds
- Whether wind direction makes a difference
- Whether the window opens and closes normally
- Whether the handle or control bar feels loose
- Whether the sound changes with the blind position
- Whether there is a draught or visible movement
- Whether any water ingress has also occurred
If possible, record a short video or audio clip from a safe position inside the room. This may help explain the problem.
Can a rattling VELUX window be repaired?
In many cases, a repair may be possible, but the solution depends on identifying the source of the movement.
If the issue involves a serviceable operating component and the window remains in good condition, maintenance or repair may be appropriate.
If the sound comes from damaged external components or the surrounding roof, the required work may be different.
AR Windows provides VELUX repair services and can advise on the most suitable next step after assessing the fault.
Should I repair or replace an older rattling VELUX window?
A rattling noise on its own is not necessarily a reason to replace an entire roof window.
The overall condition of the window is much more important.
Repair may be appropriate
The window is otherwise in good condition and the noise comes from a component that can be repaired or replaced.
Replacement may be appropriate
The window is older and also has failed glazing, deteriorating timber, worn mechanisms or several recurring problems.
If several age-related faults are developing together, a modern replacement VELUX window may offer better long-term value than repeated individual repairs.
Can regular servicing prevent rattling?
Servicing cannot prevent every component from wearing out, but it provides an opportunity to inspect the operation and condition of a roof window.
Developing problems such as unusual stiffness, wear or changes in the way a window closes may be identified before they become more disruptive.
AR Windows provides VELUX maintenance and planned servicing through our Annual Service Contract.
When should I arrange an inspection?
If the rattling is new, persistent or getting worse, it is sensible to arrange an assessment.
More urgent attention is appropriate if the window cannot be secured, there is visible movement of external components, water is entering or the window appears damaged.
During severe weather, avoid attempting repairs yourself. If the window cannot be secured or there is an immediate safety concern, keep clear of the affected area and seek appropriate professional assistance.
What information should I send AR Windows?
To help us understand the problem, please provide as much of the following information as you safely can:
- A photograph of the complete roof window
- A photograph of the VELUX product code
- The approximate age of the window, if known
- A description of where the rattling seems to originate
- Whether the noise only occurs during windy weather
- Whether the window opens and closes normally
- Details of any draughts, leaks or other problems
- A short audio or video recording, if safely possible
The VELUX product code is particularly useful when identifying the model and determining whether suitable replacement components may be available.
Is your VELUX window rattling?
Send AR Windows the window code, photographs and a description of the noise. We can help assess whether maintenance, repair or replacement is likely to be the most appropriate solution.
Final thoughts
A rattling VELUX window is not always a sign of a major problem, but it is worth understanding what is causing the noise.
The source may be a loose internal accessory, an operating component, movement within the sash or something associated with the external installation.
If the rattling is new, recurring or accompanied by difficulty closing the window, arranging a professional inspection is generally more sensible than trying to silence the noise with temporary fixes.
AR Windows can assess your roof window and advise whether maintenance, repair or replacement is the most suitable next step.
