What do roof lanterns in Briton Ferry involve?
Roof lanterns in Briton Ferry means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the SA11 district and the rest of West Glamorgan, with a survey before any price is fixed.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Briton Ferry, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
From Briton Ferry to Neath, Port Talbot and Swansea, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Solar-control or self-cleaning glass
- LED lighting in the plaster box
- Opening vents with electric control
- Aluminium or uPVC systems
- Rectangular, square or bespoke sizes
- Light from every angle across the day
- Double or triple glazed with solar-control options
Things we check at survey
- Needs a strong, level kerb or upstand
- Larger lanterns may need a steel or timber ring beam
Planning, building control and Briton Ferry
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Questions about roof lanterns in Briton Ferry
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.
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.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
How do I book a survey in Briton Ferry?
