Skylight replacement for Risca: the essentials
Skylight replacement in Risca means replacing tired domes and failed glass with a modern rooflight. We cover the NP11 district and the rest of Gwent, 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. Skylight replacement suits older extensions due a modern rooflight.
We work across Gwent, including Risca, and in neighbouring towns such as Newport, Gwent and Cwmbran. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Dome to flat glass upgrade
- Fixed to electric opening
- Roof window replacement in pitched roofs
- Upstand rebuild and insulation
- Misted glass unit replacement only
- Cures most chronic leaks
- Usually done in a day
Things we check at survey
- Upstand and roof condition decide the scope
- Old glass and domes are disposed of responsibly
Do you need permission in Risca?
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.

Common questions
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Do I need to be at home for the survey in Risca?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.

Yes. We carry out skylight replacement in Risca and across Gwent. Send your postcode and we will offer a survey date when we reply.
