Roof lanterns for Pontardawe: the essentials
Thinking about roof lanterns in Pontardawe? The short answer: hipped glass lanterns that lift the ceiling of orangeries 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. In Pontardawe, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
Jobs in Pontardawe are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your Pontardawe project
- Solar-control or self-cleaning glass
- LED lighting in the plaster box
- Opening vents with electric control
- Aluminium or uPVC systems
- Internal and external colours
- Double or triple glazed with solar-control options
- Slim aluminium bars, more glass
Things we check at survey
- Plaster-box depth affects how the lantern looks from below
- Larger lanterns may need a steel or timber ring beam
Do you need permission in Pontardawe?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Roof lanterns in Pontardawe: questions
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Do I need to be at home for the survey in Pontardawe?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Pontardawe?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
