What do flat rooflights in Neath involve?
Thinking about flat rooflights in Neath? The short answer: fixed double or triple glazed rooflights for flat roofs and extensions. The longer answer depends on your roof, which is why we survey before we price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
Neath is around 11 km from Swansea, and we survey and fit throughout that part of West Glamorgan, including the SA11 district.
Specification options
- Plastered or lined internal reveal
- Double or triple glazing
- Frame colours: anthracite, black, white or RAL
- Integral or fitted blinds
- Solar-control or self-cleaning outer pane
- Double or triple glazed with a warm-edge spacer
- Slim sightlines from inside — mostly glass, little frame
What to check first
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- New openings in an existing roof need a structural check on joists
Planning, building control and Neath
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
Read the planning permission guide before you commit to a design.

Common questions
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Do you fit flat rooflights in Neath?
Yes. We survey and fit flat rooflights in Neath and across West Glamorgan. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Neath?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
