Correctly repairing a rooflight requires the glazing, seals, frame, upstand and surrounding roof covering to be assessed together. A proper inspection can help distinguish between condensation, glazing failure and external water ingress.
Skylight, Rooflight and Roof Lantern Work Throughout East Sussex
Local specialists throughout East Sussex can repair and replace fixed, opening and powered rooflights. A specialist can inspect the unit and explain whether a targeted repair or complete new skylight offers better value.
Leaking Skylight Repairs
Leaks around skylights and rooflights can appear during heavy rain or only when rain is driven across the roof by strong winds. The contractor should inspect the complete installation before deciding what needs repairing.
Simply applying sealant around the frame may not provide a lasting solution. The specialist may need to repair the upstand, flashing or roof covering as well as the visible unit.
Repairing Skylights in Felt, EPDM and GRP Roofs
Flat roof skylights can leak through the glazing, frame, kerb or surrounding waterproof membrane. A repair may require resealing the unit, rebuilding the upstand or renewing the roof covering around its perimeter.
Repairing Skylights in Tiled or Slated Roofs
Pitched roof skylights may use flashing systems similar to standard roof windows. The flashing should be checked at the head, sides and lower apron of the skylight.
Cracked or Broken Skylight Glass Repairs
Skylight glass can crack because of impact, thermal stress, storm damage or movement within the frame. The contractor will need accurate dimensions and the correct safety, thermal and solar-control specification.
Cloudy or Condensation-Filled Skylight Units
Misting between the panes normally indicates that the sealed glazing unit has failed. A complete skylight replacement may offer better value when the frame, controls or waterproofing have also deteriorated.
Draught and Weather Seal Repairs
Rubber seals and gaskets can flatten, split or become brittle as they age. General-purpose sealant or unsuitable draught strips may interfere with normal operation.
Repairs to Timber, Aluminium and PVC Skylight Frames
Skylight frames can suffer from rot, corrosion, distortion and accidental damage. The source of moisture should be corrected before damaged finishes or frame sections are repaired.
Stiff or Broken Skylight Mechanisms
Opening skylights may develop stiff hinges, damaged handles or faulty winding mechanisms. Obsolete operating components can sometimes make full replacement more practical.
Electric Opening Rooflight Faults
Electric skylights can develop faults with motors, switches, transformers, wiring and control units. Some older motors and controls may no longer have compatible replacement parts.
Faulty Solar Skylight Systems
Solar-powered skylights may stop operating because of battery, panel, motor or control faults. Where the original system is obsolete, upgrading the complete powered unit may be considered.
Skylight Weather Sensor Repairs
Many powered skylights include a sensor designed to close the unit when rain is detected. The contractor should also check whether the motor and control unit respond normally.
Powered Skylight Accessory Repairs
Internal blinds can jam, tear or come away from their guide rails. In some cases, a new blind can be fitted without carrying out work to the skylight itself.
Cracked or Discoloured Rooflight Dome Replacement
Acrylic and polycarbonate roof domes can crack, become brittle or discolour after long exposure to sunlight and weather. The contractor should check the dimensions, number of skins and fixing arrangement before ordering.
Roof Lantern Glazing and Seal Repairs
Roof lanterns can leak around glazing bars, end caps, seals and perimeter joints. Repairs may involve glazing, seals, cappings, drainage channels or perimeter waterproofing.
Repairs to Sun Tunnels and Light Pipes
Sun tunnels can suffer from damaged external domes, leaking flashing, disconnected tubes and condensation. Repairs may involve reconnecting tube sections, replacing the dome or renewing the flashing.
Skylight Replacement Services in East Sussex
Not every skylight fault requires a complete replacement. An older skylight may no longer provide the insulation, weather resistance or operation expected from a modern product.
Homeowners may choose a new rooflight where the existing unit has:
- Repeated leaks despite previous repairs
- A broken acrylic dome or glass panel
- Cloudy glazing combined with frame or seal deterioration
- Rotten, warped or corroded frames
- Replacement parts that are unavailable or uneconomical
- Cold draughts around an older rooflight
- Overheating or excessive solar gain
- A unit installed on an inadequate kerb or upstand
- A renovation involving a larger or more modern rooflight
- A wider flat roof renewal or extension refurbishment
Direct Rooflight Replacement
Some rooflights can be replaced using the original opening after the supporting structure has been checked. The surrounding waterproofing should normally be renewed or properly reconnected rather than relying on old seals.
Increasing the Size of a Rooflight
A larger roof opening can improve the view and make the space beneath feel more open. The work may require new structural supports, a larger kerb and extensive changes to the roof covering.
Replacement Fixed Rooflights
Modern fixed units are available with flat glass, domed and specialist glazing designs. The new product must suit the roof pitch, kerb and waterproofing system.
Replacement Ventilating Rooflights
Ventilating rooflights can be useful in kitchens, bathrooms and warm extensions. The selected opening method should be practical for the height and position of the unit.
Powered Rooflight Replacement
Electric controls can make regular ventilation easier in kitchens, extensions and stairwells. The project may include actuators, switches, remote controls, rain sensors and electrical work.
Replacement Structural Glass Rooflights
Rooflights fitted into terraces, balconies and floors need specialist structural assessment. Replacement may involve heavy structural glazing, lifting equipment and changes to the supporting frame.
Replacement Access Rooflights
Older access units can become difficult to operate, poorly insulated or insecure. The size, opening direction, safety features and internal access arrangement should be considered before replacement.
Replacement Smoke Vent Rooflights
A faulty smoke vent should not be treated as an ordinary domestic opening skylight. Inspection, replacement and commissioning may need to follow specific fire-safety requirements.
Replacement Acrylic and Polycarbonate Domes
A new dome may improve daylight and weather protection without requiring a completely new roof opening. The contractor should measure the existing unit carefully and inspect the fixings and seals.
Replacement Frameless-Style Rooflights
A flat-glass replacement may provide improved clarity and resistance to discolouration. The kerb dimensions, roof pitch and drainage details must suit the selected unit.
Replacement Lantern Roof Systems
Replacement may form part of a wider extension or flat roof refurbishment. The supporting kerb must be level, correctly sized and structurally suitable.
Problems Skylight Contractors Can Investigate
Specialists across East Sussex can investigate issues such as:
- Water dripping from the skylight frame
- Damp patches on the ceiling below
- Water ingress after storms
- Cracked, chipped or shattered glass
- Condensation trapped between panes
- High humidity and cold-surface problems
- Mould around the skylight reveal
- Air leakage through failed seals
- A failed manual winding mechanism
- A skylight that will not close securely
- Electric rooflights that no longer respond
- Remote pairing and control problems
- Rotten wooden frames
- Damaged glazing bars
- Discoloured plastic skylight panels
- Ponding water around a flat roof skylight
- Splits in the surrounding waterproof membrane
- Movement in the supporting structure
- Leaks around roof lantern glazing bars
- Disconnected reflective tube sections
- Weather-related glazing and frame faults
- Poor original installation
How Skylight Problems Are Diagnosed
A full inspection can help determine whether the fault lies with the glazing, frame, kerb or roof covering.
Depending on the problem, the contractor may:
- Check labels, product codes and dimensions
- Assess the condition of the transparent or translucent covering
- Test hinges, handles and opening mechanisms
- Inspect rain sensors, switches and wiring
- Look for gaps between the opening section and frame
- Examine flashing and external cappings
- Check whether the base is level, sound and correctly sized
- Assess whether the roof covering has detached from the kerb
- Check tiles, slates, underlay and battens
- Check for cold gaps around the frame
- Carefully dismantle affected parts
- Fit compatible glazing, seals or mechanisms
- Reconnect the roof membrane to the upstand
- Confirm that powered controls and sensors operate
- Make good internal finishes where included
- Dispose of redundant materials safely
Rooflight Installation Details Across East Sussex
Felt Roof Skylights
Cracked, lifted or poorly bonded felt can allow water beneath the roof covering. The finished detail should allow water to drain away without ponding against the skylight.
EPDM Skylight Repairs
Leaks can develop where the rubber has lifted, stretched or been poorly joined around the skylight. Corners and changes in level require careful detailing.
GRP Skylight Repairs
The joint between a fibreglass roof and the skylight upstand must remain fully waterproof. Movement in the kerb should be corrected before repairing the laminate.
Liquid Roof Skylight Repairs
Failure may occur where the substrate was damp, poorly prepared or moved after installation. Simply applying a different coating over the top may not provide a reliable bond.
Tile and Slate Skylight Repairs
Tiles and slates should direct water into the flashing channels rather than beneath them. The underlay beneath the covering should also be checked for deterioration.
Common Rooflight Makes and Product Types
Contractors may encounter current products, discontinued models and unbranded units. The installer should confirm compatibility before ordering components or a replacement unit.
VELUX Skylights and Flat Roof Windows
VELUX products can include fixed, electric and solar-powered designs together with flat-glass and curved-glass covers. Older products may need to be compared with a current equivalent before work is priced.
FAKRO Skylights and Flat Roof Windows
FAKRO flat-roof ranges include glazed and domed product designs for bringing daylight into rooms below flat roofs. A replacement may require a new base, kerb connection or surrounding waterproofing.
Brett Martin Rooflights
Homes and extensions may contain Brett Martin domes, flat-glass rooflights or polycarbonate daylight products. Complete replacement may be considered where the kerb, frame or opening system is also defective.
Whitesales Rooflights
Whitesales products can include polycarbonate domes, flat-glass rooflights and specialist opening units. Replacement parts and dimensions should be confirmed before the existing rooflight is dismantled.
Coxdome and Mardome Rooflights
Polycarbonate domes may be fixed, opening or linked to ventilation systems. A complete rooflight may offer better performance where the original base is damaged or poorly insulated.
Glazing Vision Rooflights
These rooflights may be heavier and more complex than standard domestic skylights. The supporting structure should also be checked where movement or leaks have occurred.
Korniche and Atlas Roof Lanterns
Roof lantern work can involve glazing, bars, end caps, seals and perimeter weathering. Internal making good may be needed after the old lantern is removed.
Other Skylight and Rooflight Manufacturers
Many older properties contain discontinued or unbranded rooflight products. Compatibility with the opening, kerb and roof covering should be established before removal.
How Much Do Skylight Repairs Cost in East Sussex?
There is no single standard price because skylights range from small roof domes to large glazed lanterns. The condition of the surrounding roof covering can also have a major effect on the total.
Factors that may affect the price include:
- The product design and dimensions
- The type of hinges, actuators and controls
- Glass, acrylic or polycarbonate construction
- Double, triple, laminated or solar-control glass
- Manufacturer-specific seals, motors and fixings
- The height, roof pitch and access
- The number of installers needed
- Whether the supporting base needs rebuilding
- The type of surrounding roof covering
- Whether roof falls need correcting
- Whether internal finishing is included
- Electrical testing and connection work
- Safe disposal of damaged glazing
- Possible access savings on a larger project
Comparing detailed quotations is the best way to establish a realistic price for the work. Our free matching service makes it easier to compare skylight prices across East Sussex.
Is Skylight Repair Worthwhile?
Repair may be the most economical choice where the frame and main glazing remain in good condition. An older skylight with several faults can become expensive to keep repairing.
Comparing the total installed cost and guarantee can help identify the better long-term option.
Do Skylight Repairs or Replacements Need Approval?
Replacing damaged glazing, seals or operating parts usually does not alter the external appearance of the property. Planning permission may also be relevant where a new rooflight projects substantially or affects a protected elevation.
Building regulations may apply where the structural opening changes or the work affects insulation, safety glazing, ventilation or fire safety.

Frequently Asked Questions About Skylight Repairs and Replacement in East Sussex
How much do skylight repairs cost in East Sussex?
Skylight repair costs in East Sussex depend on the type and size of the unit, the fault, access and the surrounding roof covering. Replacing a seal or small mechanism normally costs less than fitting new glazing or replacing the complete rooflight. Scaffolding, waterproofing and internal repairs can also affect the total.
Can a leaking skylight be repaired?
Many leaking skylights can be repaired if the frame and glazing remain in reasonable condition. The work may involve replacing seals, repairing flashing, renewing the roof membrane or correcting faults around the kerb. A proper inspection is needed to locate the actual entry point.
Why is my skylight leaking during heavy rain?
A skylight that leaks during heavy or wind-driven rain may have damaged flashing, failed seals, blocked drainage or defective waterproofing around the upstand. Water may also enter through the surrounding roof and travel before appearing beside the skylight.
Can misted skylight glass be replaced separately?
In many cases, a failed sealed glazing unit can be replaced without changing the complete skylight. Glass-only replacement is most suitable where the frame, seals, kerb and opening mechanism remain in good condition.
Should I repair or replace an old skylight?
A repair may be worthwhile where the problem is limited to a seal, flashing detail, glazing unit or operating component. Complete replacement may offer better value where the frame is damaged, several components have failed or compatible parts are no longer available.
How long does a skylight repair or replacement take?
A minor repair may sometimes be completed during one visit. A straightforward replacement may take a day, while large rooflights, lanterns, structural alterations, difficult access and extensive waterproofing work can take longer.
Do skylight repairs require scaffolding?
Scaffolding requirements depend on the height, roof pitch, unit position and work involved. Some skylights can be reached safely from a flat roof or inside the property, while others require a scaffold, access tower or specialist lifting equipment.
Can a skylight be replaced with a different brand?
A skylight can sometimes be replaced with a product from another manufacturer, provided that the dimensions, kerb, roof pitch and waterproofing details are compatible. Alterations to the opening or surrounding roof may be required.
Do I need planning permission to replace a skylight in East Sussex?
A similar replacement in the same opening will not normally require a separate planning application. Enlarging or repositioning the skylight, changing the external appearance, or working on a listed building or conservation area property may require consent.
What should be included in a skylight quotation?
A detailed quotation should identify the proposed repair or replacement product, glazing, seals, labour, access equipment, roof waterproofing, internal making good, waste removal, VAT where applicable and available guarantees.
Are skylight contractors insured?
Contractors introduced through the service may be asked to provide business, insurance and reference information. Homeowners should still request evidence of suitable and current public liability insurance before appointing a specialist.
