Roof lanterns for Rhondda: the essentials
For Rhondda homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Think of roof lanterns for rooms that need height as well as light.
We cover all of Rhondda and the CF42 district, and nearby Tonypandy and Aberdare.
Options we can specify in Rhondda
- Aluminium or uPVC systems
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- Internal and external colours
- Opening vents with electric control
- Classic look that suits period and modern homes
- Double or triple glazed with solar-control options
What to check first
- Some designs project above the roof enough to affect planning on certain houses
- Larger lanterns may need a steel or timber ring beam
Planning, building control and Rhondda
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

Roof lanterns in Rhondda: 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 roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
