Hinged roof access rooflights for Caernarfon: the essentials
We handle hinged roof access rooflights across Gwynedd, including Caernarfon. In short: hinged glazed hatches over a stair or ladder for roof terrace access. 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. Think of hinged roof access rooflights for reaching a roof terrace, plant area or flat roof from a stair or ladder.
Caernarfon is around 13 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL55 district.

Consents for hinged roof access rooflights 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. 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.

Questions about hinged roof access rooflights in Caernarfon
Can it replace an old loft hatch?
Where there is a flat roof above, yes. On a pitched roof, an access roof window is the equivalent.
Does it let in as much light as a normal rooflight?
Yes — closed, it is a glazed rooflight. The frame is slightly deeper to carry the hinge and seals.
Can it be opened from the roof?
Many units have an external handle or key for opening from outside. If you need that, tell us at survey.
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.
Can you work alongside my builder in Caernarfon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
