Short answer
Checking the flashing around your roof window is essential when leaks occur, as flashing issues are often the primary cause. Regular maintenance of seals and drainage channels helps prevent water ingress and expensive repairs. Address minor wear signs early to ensure the long-term performance and durability of roof windows and skylights.
Address leaks promptly to prevent further damage and costly repairs.

How to recognise it
- A visible drip at the lining can indicate a failure in the surrounding flashing, allowing moisture to penetrate.
- Misted or fogged panes suggest moisture has entered between double glazing, diminishing insulation effectiveness.
- A rotten timber kerb often signifies prolonged water exposure from unseen leaks or inadequate drainage.
- A stuck sash, caused by rust or debris, shows poor maintenance or failing weather seals.
- Water stains on the interior walls or ceilings below indicate ongoing leaks that need immediate investigation.
- Excessive condensation inside the window usually points to poor ventilation or inadequate sealing.
- Cracked or peeling paint around the frame often results from moisture seepage due to incorrect installation.
Common causes
- A failed flashing kit diverts water improperly, leading to leakage around the window frame.
- Blocked drainage channels prevent water from escaping, causing seepage into the roof's structure.
- An end-of-life unit with degraded seals allows water ingress and lowers insulation efficiency.
- Improperly sized or fitted windows cause gaps, letting water and air penetrate the housing.
- Accumulated debris in the window track blocks closure mechanisms, resulting in weather exposure.
What you can do yourself
- 01Clear outer drainage channels regularly to prevent blockages, ensuring water flows away and avoids seepage.
- 02Check the window seals twice a year to identify wear early, protecting against drafts and leaks efficiently.
What the roofer does
- Reflashing the window corrects leakage by redirecting water away, necessary when existing flashing is faulty.
- Replacing a window at the end of its lifespan resolves persistent leaks and insulation failure effectively.
- Renewing linings and seals fixes minor leaks and drafts, suitable when flashing remains intact.
- Cleaning and clearing drainage channels prevents blockages, ensuring proper water flow if addressed early.
- Adjusting or replacing catches and hinges remedies stuck sashes, restoring smooth operation and weather protection.
How the job usually runs
- 01Assess and document the current installation to identify problems and decide between repair or replacement.
- 02Carefully remove the old unit while preventing damage to surrounding roof materials or interior finishes.
- 03Install and properly flash the new window to ensure all seals and insulation are correctly placed and prevent future leaks.
- 04Inspect and test the new installation by simulating rain to check for leaks and confirm effective water redirection.
- 05Repair any interior plaster or painting affected by the replacement, ensuring a neat finish inside.
What the price depends on
CentralRoofers does not publish a fixed price. That is agreed with the firm you appoint. Differences usually come from:
- The complexity of the installation site can raise costs due to the need for customised work and solutions.
- The choice of materials affects pricing as higher quality options generally provide better durability and insulation.
- Labour costs rise if skilled work requires more time, especially in complex or high installations.
- Access difficulties, such as height or restricted space, can increase costs due to additional safety measures required.
- Urgency of repair or replacement may affect price as emergency services can incur premium rates.

Questions
How do I determine the severity of a leak in my roof window?
Check for visible drips, water stains on walls, or signs of dampness around the window. If you notice significant water ingress or structural damage like a rotten timber kerb, it's urgent. Minor condensation usually indicates less severe issues, such as poor ventilation. Monitor symptoms over time and consult a professional for persistent or worsening conditions to prevent further damage.
What regulations should I be aware of when replacing a roof window?
In the UK, installing or replacing roof windows may require compliance with building regulations, especially concerning thermal performance and structural safety. Planning permission is usually not needed unless your property is listed or in a conservation area. Always check local council requirements and ensure all work adheres to safety standards. Using a certified installer can help meet these obligations efficiently.
What should a quote for replacing my skylight include?
A detailed quote should outline labour costs, the price of materials, and any additional charges for access equipment or safety precautions. Include timelines for work completion and any warranties on materials and workmanship. Also, ensure it covers removal of the old unit and any necessary interior repairs. Clear inclusion of all expected work helps prevent unexpected costs later.
How can I minimise the risk of leaks in my skylight?
Regularly inspect the flashing, seals, and drainage channels to ensure they are intact and unblocked. Schedule routine maintenance to identify wear early, before issues escalate. Ensure proper ventilation to reduce condensation and check for any signs of water ingress promptly. Professional inspections every few years can also catch potential problems before they develop into major concerns.
