What do flat rooflights in Ammanford involve?
Thinking about flat rooflights in Ammanford? 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.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
We work across Dyfed, including Ammanford, and in neighbouring towns such as Pontardawe and Gorseinon. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Integral or fitted blinds
- Rain sensor if paired with an opening unit
- Insulated kerb or timber upstand built to suit
- Double or triple glazing
- Square, rectangular or long-format sizes
- Inner pane laminated for safety overhead
- Even, top-down daylight across the whole room
Before you order: points to check
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Planning and building rules for Ammanford
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Common questions
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 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.
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.

Yes for new installations. Repair visits are charged, and we tell you the price before we book.
