What do walk-on rooflights in Bangor, Gwynedd involve?
We handle walk-on rooflights across Gwynedd, including Bangor, Gwynedd. In short: structural glass you can stand on, set flush into terraces and floors. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Walk-on rooflights suit terraces where the light below matters as much as the space above.
We cover all of Bangor, Gwynedd and the LL57 district, and nearby Llangefni and Caernarfon.

What to check first
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
- Structural support and the design load must be confirmed by the manufacturer or an engineer
Do you need permission in Bangor, Gwynedd?
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.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
Read the planning permission guide before you commit to a design.

Walk-on rooflights in Bangor, Gwynedd: questions
Will it sit flush with my paving?
Yes — the unit is set on its own upstand so the glass finishes level with the surrounding paving or decking.
Is the glass slippery?
Walk-on glass has an anti-slip finish, usually a ceramic frit or etched pattern. Like any outdoor surface it needs cleaning to stay effective.
How much weight can a walk-on rooflight take?
It depends on the model and size. Manufacturers state a design imposed load for each unit; we only specify a unit whose rating suits the use, such as a private terrace or a busier area.
Do I need to be at home for the survey in Bangor, Gwynedd?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Bangor, Gwynedd?
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.
