Free Roof Window and Skylight Repair Quotes in Perth, Perth and Kinross
A leaking or damaged roof window can affect the comfort and condition of the room below. Problems can involve double-glazed unit.
Water around a roof window does not always mean the complete unit needs replacing. Rainwater can enter where flashing has lifted or failed and then damage plasterboard or timber beneath the window.

- Discoloured or brittle plastic rooflights
- Failed seals on older plastic skylights
- Leaks around sun tunnels
- Incorrect flashing for the roof material
- Repeated water ingress around the same unit
- Storm or impact damage
Condensation and external water ingress can sometimes create similar symptoms. A roofer may need to check surrounding roof materials before recommending a repair.
Signs a Roof Window Needs Repair
The first sign of failure may be a draught, misted pane or small damp mark. You may want to contact a roof window specialist if you notice:
- Water dripping around the frame
- Water staining or damaged plaster
- Gaps around the opening section
- Condensation between panes
- Visible damage to the glazing
- The sash sticking in the frame
- A roof window that will not close fully
- Movement within the frame
- Dark staining in the corners of the frame
- Broken tiles or slates nearby
- Blocked drainage channels
- Open joints around the kerb
- An electric window no longer operating
- Sealant lifting from the frame
Rooflights can be difficult to reach safely without suitable equipment. Photographs taken from inside may help explain the problem, but a complete diagnosis often requires an external inspection.
Common Causes of Rooflight Water Ingress
The window, flashing and surrounding roof materials need to work together. Leaks commonly develop because of:
- Flashing that has lifted, cracked or corroded
- An incorrect flashing kit for the roof covering
- Gaps, bad positioning or insufficient weatherproofing
- Broken or displaced tiles and slates
- Moss, leaves or debris preventing water from escaping
- Failed frame seals
- Poorly formed underlay details around the opening
- Condensation caused by high humidity
- Missing or poorly fitted insulation around the frame
- A failed double-glazed unit
- Membrane failure at rooflight corners
- Standing water around a low kerb
- Expansion, contraction or settlement
- Temporary repairs using incompatible sealants
Both external water ingress and humidity may affect the same window. A contractor should consider the condition of the seals and flashing.
How Roof Windows Are Repaired in Perth
A complete new window is not always required. Common work includes:
Replacing or Repairing Flashing Kits
The flashing directs rainwater around the frame and onto the roof covering. Repairs may involve correcting poorly fitted pieces.
The replacement flashing should be compatible with the roof window model. Nearby roof coverings and underlay may also need realigning.
Tile and Slate Repairs Around Roof Windows
Broken or badly cut tiles can leave gaps around a roof window. Work may include refixing displaced coverings.
Renewing Gaskets and Frame Seals
Rubber seals can harden, split or flatten as they age. Suitable replacement seals may be fitted where the frame is otherwise in good condition.
Roof Window Glass Replacement
A misted or cracked glass unit can often be replaced without changing the complete roof window. The replacement should match the required safety glass specification.
Depending on the unit, options may include solar-control glass. The contractor should confirm what glass is being supplied.
Roof Window Mechanism Repairs
A window that does not close properly can create draughts and leaks. Repairs may include fitting a new handle.
Timber Frame Repairs
Minor timber deterioration may be repairable if addressed early. Work can include drying and preparing the frame.
If the frame is unable to hold replacement parts, full window replacement may be more practical.
Flat Roof Skylight Repairs
Flat roof skylights depend on a watertight kerb and correctly dressed membrane. Repairs may involve improving drainage around the unit.
Motorised Window Faults
Electric roof windows may develop faults with motors, switches, remotes or rain sensors. Repair work can include renewing sensors.
Sun Tunnel and Tubular Skylight Repairs
Sun tunnels can leak around the roof fitting or develop condensation inside the tube. Repairs may involve renewing flashing.
When Is Roof Window Repair Worthwhile?
Many roof window faults can be repaired without replacing the whole unit. Repair may be suitable where the problem involves hinges or handles.
Replacement may be more practical if earlier repairs repeatedly leak. A new unit may also provide better insulation.
Request a clear comparison between repair and renewal. For a complete replacement, confirm whether the quotation includes VAT.

Rooflight Repair Price Factors
- The make, model and age of the window

- The type of roof covering
- Whether nearby tiles, felt or battens also need repair
- Building height and roof pitch
- Site setup and working-at-height costs

- The number of windows or skylights requiring attention
- Whether temporary protection is needed before the full repair
Condensation or a Leaking Roof Window?
Not every wet roof window is leaking from outside. Condensation is more likely where washing, cooking or bathing creates moisture.
An external leak is more likely if moisture follows the direction of the wind. Misting trapped between panes normally indicates a failed sealed glazing unit rather than room condensation or a roof leak.
A roofer or roof window specialist should consider ventilation and insulation before deciding what work is required.
Emergency Roof Window and Skylight Repairs in Perth
Storm or impact damage can leave the unit unsafe. A contractor may initially apply temporary waterproof protection.
Emergency work may not be the final repair. Ask the contractor to confirm whether the window can still be used.

How much does a roof window repair cost in Perth?
Roof window repair costs in Perth depend on the fault, unit type, replacement parts and access. Minor handle, hinge or seal work may cost around £100–£450, while flashing replacement, glazing renewal or more extensive roof repairs can cost £400–£1,500 or more.
Why is my roof window leaking?
Common causes include failed flashing, broken tiles or slates, blocked drainage channels, damaged underlay, worn frame seals and poor installation. Water can travel around the frame before appearing inside, so the surrounding roof should also be inspected.
Can a roof window be repaired rather than replaced?
Yes, many roof window faults can be repaired. Flashing kits, seals, glass units, hinges, handles and locks may all be replaceable. Full replacement may be more practical if the frame is badly damaged, several components have failed or suitable parts are no longer available.
Can misted roof window glass be replaced?
Yes. Misting between the panes normally means the sealed double-glazed unit has failed. In many cases, the glazing can be replaced while the existing sash and frame remain in place, provided they are still in good condition.
Why is there condensation on my roof window?
Condensation on the room-facing glass is often caused by high indoor humidity, limited ventilation or cold bridging around the reveal. Misting between the panes points to a failed glazing unit, while moisture appearing during rainfall may indicate an external leak.
Can flashing around a roof window be replaced?
Yes. Damaged or unsuitable flashing can often be removed and replaced with a compatible kit. The roofer may also need to lift nearby tiles or slates, repair underlay and check drainage channels around the frame.
Can hinges and handles on roof windows be repaired?
Many hinges, handles, locks and operating mechanisms can be serviced or replaced. Availability depends on the make, model and age of the unit. The window should also be checked for alignment and frame damage.
Will scaffolding be needed for a roof window repair?
Scaffolding may be required depending on the building height, roof pitch, unit position and scope of the work. Some repairs can be completed from inside or with another safe access method. Any access costs should be shown in the quotation.
Do roof window repairs need planning permission in Perth?
Most minor repairs and like-for-like component replacements do not normally require planning permission. You should check with Perth and Kinross Council if the property is listed, located in a conservation area or if the work will enlarge, reposition or noticeably alter the roof window.
How can I find a roof window repair specialist in Perth?
Compare detailed quotations from independent roofers and ask about their experience with roof windows, skylights, flashing kits and replacement glazing. Check insurance, references, access costs, parts, payment terms and any workmanship guarantee before appointing a contractor.
