What do flat rooflights in Risca involve?
We handle flat rooflights across Gwent, including Risca. In short: fixed double or triple glazed rooflights for flat roofs and extensions. 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. Flat rooflights suit kitchen extensions, side returns and flat-roofed back rooms.
Jobs in Risca 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.
What you can choose
- Solar-control or self-cleaning outer pane
- Plastered or lined internal reveal
- Double or triple glazing
- Insulated kerb or timber upstand built to suit
- Integral or fitted blinds
- Slim sightlines from inside — mostly glass, little frame
- Inner pane laminated for safety overhead
Before you order: points to check
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- New openings in an existing roof need a structural check on joists
Planning and building rules for 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. 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.
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.

Common questions
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Do you fit flat rooflights in Risca?
Yes. We survey and fit flat rooflights in Risca and across Gwent. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Risca?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
