Skylight work can involve more than applying fresh sealant around the visible frame. Rainwater can enter elsewhere in the roof and travel before becoming visible inside the property.
What Skylight Work Can Local Specialists Carry Out?
Skylight contractors serving Porthmadog work on many types of pitched and flat roof glazing. Some faults can be repaired using replacement components, while more extensive damage may make complete replacement more practical.
Repairs for Water Entering Around a Skylight
Water ingress is one of the most common skylight problems reported by homeowners in Porthmadog. The water may come through the skylight itself or enter through the surrounding roof covering.
Repeated patching may make the true leak more difficult to trace later. A lasting solution may require roofing materials to be lifted, waterproofing renewed or damaged skylight parts replaced.
Flat Roof Rooflight Leak Repairs
Rainwater can remain around a flat roof skylight where the roof fall is poor or nearby outlets are blocked. The contractor should inspect the skylight together with the surrounding felt, EPDM, GRP or liquid waterproofing.
Pitched Rooflight and Roof Window Repairs
Broken tiles, damaged slates and torn roofing underlay around the opening can also allow water inside. A specialist may need to lift and reinstate the surrounding roof covering to complete the repair properly.
Replacement Glazing for Skylights and Rooflights
Broken skylight glass can allow water into the property and should be made safe promptly. Where the frame remains in good condition, the glazing may be replaced without changing the complete skylight.
Failed Double-Glazed Rooflight Repairs
Condensation trapped inside a double- or triple-glazed unit cannot usually be removed through cleaning. The glazing may be replaceable where the frame and seals remain sound.
Replacement Rooflight Seals
Perished gaskets can prevent the sash or glazed lid from closing evenly. The repair may involve fitting compatible replacement seals and adjusting the closing mechanism.
Damaged Rooflight Frame Repairs
Metal frames and fixings can corrode where water has remained trapped around the skylight. Minor deterioration may be repairable, while extensive structural damage can make full replacement more practical.
Opening Rooflight Repairs
Regular use, corrosion and limited maintenance can eventually wear the moving parts. Repair work may include cleaning, adjustment, lubrication or replacement components.
Powered Rooflight Motor Repairs
Electrical problems can affect the actuator or controls rather than the skylight frame itself. A suitably experienced contractor can test the system and identify the failed component.
Solar Rooflight Control Repairs
Remote pairing problems can also make a functioning skylight appear faulty. A specialist may inspect the solar panel, battery, motor and controls before recommending replacement parts.
Automatic Skylight Closing Faults
The skylight may remain open during rain or close unexpectedly if the sensor or controls are faulty. The system may need cleaning, resetting, testing or replacement components.
Rooflight Blind Replacement
Skylight blinds are often produced for a particular model and size. A contractor may repair or replace the accessory where compatible parts are available.
Polycarbonate Roof Dome Repairs
The outer dome, inner layer, fixings or weather seals may eventually need attention. A replacement dome can sometimes be fitted where the existing base and kerb remain serviceable.
Leaking Roof Lantern Repairs
Water can also enter where the surrounding roof membrane meets the lantern kerb. The contractor should establish whether the fault lies within the lantern or the flat roof around it.
Tubular Skylight Repairs
Moisture can enter where the external unit, tube or ceiling diffuser has not been sealed correctly. The specialist should inspect the complete system from the roof covering to the internal diffuser.
Should a Skylight Be Repaired or Replaced?
A targeted repair may be suitable where the main frame and supporting structure remain sound. Replacement may offer better value where the unit has several faults, extensive damage or obsolete components.
A complete replacement may be considered where the unit has:
- A long-running leak that has not been corrected by resealing
- Cracked, shattered or badly damaged glazing
- Failed double glazing in an ageing skylight
- A frame that no longer supports or seals the glazing correctly
- Obsolete hinges, motors or controls
- Outdated glazing and excessive heat loss
- An older clear unit that makes the room too hot
- An unsuitable product for the roof pitch
- A wish to bring more daylight into the room
- An opportunity to upgrade the unit while the surrounding roof is renewed
Types of Skylight That Can Be Replaced
Direct Rooflight Replacement
Some rooflights can be replaced using the existing structural opening after it has been checked. The waterproofing should normally be renewed or correctly reconnected rather than relying on old seals.
Increasing the Size of a Rooflight
A larger opening can improve the view and make the space below 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 products are available in flat-glass, domed and specialist glazing designs. The replacement must suit the roof pitch, supporting kerb and waterproofing system.
Replacement Ventilating Rooflights
Ventilating rooflights can be particularly useful in kitchens, bathrooms and warm extensions. The selected opening method should remain practical for the height and position of the unit.
Powered Rooflight Replacement
Electric controls can make regular ventilation easier in extensions, kitchens 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 require specialist structural consideration. Replacement may involve heavy structural glass, lifting equipment and changes to the supporting frame.
Replacement Access Rooflights
Older access units may become difficult to operate, poorly insulated or insecure. The opening direction, dimensions, safety features and internal access arrangements should be considered.
Replacement Smoke Vent Rooflights
A faulty smoke vent should not be treated as an ordinary domestic skylight. Replacement and commissioning may need to follow specific fire-safety requirements.
Replacement Acrylic and Polycarbonate Domes
A new dome may improve daylight and weather resistance without requiring a new structural opening. The contractor should measure the existing product and inspect the fixings and seals.
Replacement Modern Glass Rooflights
A flat-glass unit may provide improved clarity and avoid the discolouration associated with ageing plastic domes. The kerb dimensions, drainage details and roof pitch must suit the selected replacement.
Replacement Lantern Roof Systems
Replacement may form part of a wider flat roof or extension refurbishment. The supporting kerb must be level, structurally suitable and correctly sized.
Replacement Tubular Skylights
Replacing a damaged sun tunnel can restore daylight to a hallway, bathroom or internal room. The contractor should inspect the complete route between the roof and ceiling.
Common Skylight Problems in Porthmadog
Local contractors can investigate faults such as:
- Water dripping from the skylight frame
- Damp patches on the ceiling below
- Water ingress following storms
- Cracked, chipped or shattered glass
- Condensation trapped between panes
- High humidity and cold-surface problems
- Mould around the skylight reveal
- Air leakage through worn 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 waterproof membrane

- Weather-related glazing and frame faults
- Poor original installation
What Does a Skylight Specialist Do?
A full inspection can help establish whether the fault lies in the glazing, frame, kerb or roof covering.
Depending on the fault, the contractor may:
- Check product labels, codes and dimensions
- Assess the condition of the transparent 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 controls and sensors operate
- Make good internal finishes where included
- Dispose of redundant materials safely
Repairing Skylights in Different Roofing Materials
Felt Roof Skylights
Cracked, lifted or poorly bonded felt can allow water beneath the roof covering. The finished roof should drain without water collecting against the unit.
EPDM Skylight Repairs
Leaks may develop where the rubber has lifted, stretched or been poorly joined around the skylight. Corners and changes in level require particularly careful detailing.
GRP Skylight Repairs
The connection between the fibreglass roof and upstand must remain fully waterproof. Movement in the kerb should be corrected before repairing the laminate.
Liquid Roof Skylight Repairs
Failure can occur where the base was damp, contaminated or poorly prepared. Applying an unrelated coating over the existing surface 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 roofing underlay should also be checked while the covering is lifted.
Replacement Skylights from Leading Manufacturers
Local contractors may encounter current products, discontinued models and unbranded rooflights. Compatibility should always be confirmed before replacement parts or a complete unit are ordered.
VELUX Skylights and Flat Roof Windows
VELUX ranges include fixed, electric and solar-powered flat roof windows with several cover and glazing choices. Older units may need to be compared with a current equivalent before the project is priced.
FAKRO Skylights and Flat Roof Windows
FAKRO flat-roof ranges include domed and flat-glazed products for bringing daylight into rooms below flat roofs. Replacement may require a new base, membrane connection or surrounding waterproofing.
Brett Martin Rooflights
Homes and extensions may contain Brett Martin domes, polycarbonate systems or flat-glass rooflights. Complete replacement may be more practical where the kerb, frame or opening mechanism is also defective.
Whitesales Rooflights
Whitesales products include flat-glass rooflights, polycarbonate domes and specialist opening units. Replacement dimensions and components should be confirmed before dismantling the existing rooflight.
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 a standard domestic skylight. The supporting structure should also be checked where movement or water ingress has occurred.
Korniche and Atlas Roof Lanterns
Roof lantern work can involve glass, glazing bars, seals, end caps and perimeter weathering. Internal making good may be required once the old lantern has been removed.
Other Skylight and Rooflight Manufacturers
Many older properties contain discontinued or unbranded rooflight products. Compatibility with the opening, kerb and surrounding roof should be established before removal.
Prices for Skylight and Rooflight Work Around Porthmadog
There is no single standard cost because skylights range from small domes to large glazed lanterns. The condition of the surrounding roof covering can also have a major effect on the total.

Pwllheli, Barmouth, Blaenau Ffestiniog, Conwy, Dolgellau, Menai Bridge, BeaumarisFrequently Asked Questions About Skylight Repairs and Replacement in Porthmadog
How much do skylight repairs cost in Porthmadog?
Skylight repair prices in Porthmadog depend on the size and type of the unit, the fault, access and the surrounding roof covering. Replacing a seal or small mechanism normally costs less than new glazing or a complete replacement. Scaffolding, waterproofing and internal repairs can also affect the total.
Can a leaking skylight be repaired?
Many leaking skylights can be repaired if the main frame and glazing remain in reasonable condition. Work may involve replacing seals, repairing flashing, renewing the roof membrane or correcting faults around the kerb or upstand.
Why does my skylight leak during heavy rain?
A skylight that leaks during heavy or wind-driven rain may have damaged flashing, failed seals, blocked drainage or defective waterproofing. Water can also enter through the roof above and travel before appearing beside the skylight.
Can misted skylight glass be replaced separately?
A failed sealed glazing unit can often be replaced without changing the complete skylight, provided the frame, seals, kerb and opening mechanism are still in suitable condition.
Should I repair or replace an old skylight?
A repair may be worthwhile where the fault is limited to a seal, flashing detail, glazing unit or operating mechanism. Replacement may provide better value where the frame is damaged, several components have failed or suitable parts are unavailable.
How long do skylight repairs take in Porthmadog?
A minor repair may be completed during one visit. A straightforward replacement may take around a day, while large rooflights, roof lanterns, structural alterations and extensive waterproofing work can take longer.
Do skylight repairs require scaffolding?
Scaffolding requirements depend on the property height, roof pitch, skylight position and type of work. Some units can be reached from a flat roof or inside the property, while others require scaffolding, a tower or lifting equipment.
Can a skylight be replaced with a different brand?
A skylight can sometimes be replaced with a product from another manufacturer where 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 Porthmadog?
A similar replacement in the same opening will not normally require a separate planning application. Enlarging or moving the skylight, changing the external appearance, or working on a listed building or conservation area property may require consent from Cyngor Gwynedd.
Can a roof dome be replaced without changing the base?
A damaged acrylic or polycarbonate dome can sometimes be replaced while the existing base remains in place. The base, kerb, fixings and seals must be inspected to confirm that they are still sound and compatible.
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.
