What do hinged roof access rooflights in Porthmadog involve?
We handle hinged roof access rooflights across Gwynedd, including Porthmadog. 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. Hinged roof access rooflights suit reaching a roof terrace, plant area or flat roof from a stair or ladder.
Porthmadog is around 33 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL49 district.

Planning, building control and Porthmadog
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
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.
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.
How big does an access hatch need to be?
Big enough to climb through comfortably for the stair or ladder you have. For a stair, we size it to the stair width and the headroom; for occasional plant access a smaller hatch can work.
How do I book a survey in Porthmadog?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Porthmadog?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
