What do conservation rooflights in Caernarfon involve?
We handle conservation rooflights across Gwynedd, including Caernarfon. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Typical uses for conservation rooflights include period, listed and conservation-area roofs.
Jobs in Caernarfon are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your Caernarfon project
- Flashings for slate or plain tile
- Blinds
- Central vertical glazing bar
- Manual or electric opening
- Toughened or laminated double glazing
- Traditional slim profile, sits low in the roof
- Optional central glazing bar
What to check first
- Listed building consent is needed for listed buildings
- Projection above the roof line is limited — usually as flush as possible
Do you need permission in Caernarfon?
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. 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.

Questions about conservation rooflights in Caernarfon
Are conservation rooflights double glazed?
Most modern ones are, with slim units behind the traditional frame.
Do I need consent for a conservation rooflight?
On a listed building you need listed building consent. In a conservation area, check with the council — many areas have Article 4 directions affecting roof alterations.
Will the council accept it?
We cannot promise an outcome, but a slim conservation profile fitted low in the roof is the type many conservation officers ask for.
Will I need planning permission in Caernarfon?
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.
Do I need to be at home for the survey in Caernarfon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
