Roof lanterns in Ammanford: what is involved?
Thinking about roof lanterns in Ammanford? 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.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
Neighbouring towns include Pontardawe (12 km) and Gorseinon (14 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Ammanford
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.
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.

Common questions
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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 Ammanford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Do you fit roof lanterns in Ammanford?
Yes. We survey and fit roof lanterns in Ammanford and across Dyfed. Send your postcode and we will offer a survey date when we reply.
