What do skylight repairs & leak fixes in Lancaster involve?
Thinking about skylight repairs & leak fixes in Lancaster? The short answer: leak tracing, resealing, actuator repairs and glass replacement. The longer answer depends on your roof, which is why we survey before we price.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. In Lancaster, as anywhere, skylight repairs & leak fixes are the usual choice for rooflights that have stopped opening or started dripping.
From Lancaster to Morecambe, Fleetwood and Thornton-Cleveleys, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Upstand and membrane repairs
- Glass unit replacement
- Actuator, motor and control repairs
- Resealing and re-flashing
- Planned maintenance visits
- Honest repair-or-replace advice
- Leak tracing, not guesswork
Things we check at survey
- Water tracking can show up far from the source
- Parts availability varies with the age of the unit
Do you need permission in Lancaster?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Common questions
Is it condensation or a leak?
Condensation forms on the inside face on cold days and comes back in the same pattern. A leak appears when it rains and often tracks down the reveal.
Why is my skylight leaking?
Common causes are a failed seal, a membrane that has split or lifted at the upstand, a low upstand, blocked drainage or condensation mistaken for a leak.
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
Can you work alongside my builder in Lancaster?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Lancaster?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
