How we approach roof lanterns in Tenby
Roof lanterns in Tenby means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the SA70 district and the rest of Dyfed, with a survey before any price is fixed.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Roof lanterns suit orangeries, kitchen-diners and single-storey extensions.
Tenby is around 37 km from Llanelli, and we survey and fit throughout that part of Dyfed, including the SA70 district.
What you can choose
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- Internal and external colours

- Classic look that suits period and modern homes
Things we check at survey
- Needs a strong, level kerb or upstand
- Some designs project above the roof enough to affect planning on certain houses
Planning, building control and Tenby
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. 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. 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 Tenby: 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.
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.
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 you work alongside my builder in Tenby?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Tenby?
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.
