Roof lanterns in Aberdare: what is involved?
Thinking about roof lanterns in Aberdare? 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.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Typical uses for roof lanterns include rooms that need height as well as light.
Neighbouring towns include Rhondda (6 km) and Merthyr Tydfil (6 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Aberdare
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. 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.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Roof lanterns in Aberdare: questions
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.
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 you fit roof lanterns in Aberdare?
Yes. We survey and fit roof lanterns in Aberdare and across Mid Glamorgan. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Aberdare?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
