Flat rooflights in Pontardawe: what is involved?
For Pontardawe homes and buildings we offer flat rooflights: fixed double or triple glazed rooflights for flat roofs and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. In Pontardawe, as anywhere, flat rooflights are the usual choice for landings, bathrooms and rear extensions with flat roofs.
From Pontardawe to Neath, Ystradgynlais and Briton Ferry, the same survey-first process applies: measure, specify, fix the price, then fit.
Choices for your Pontardawe project
- Solar-control or self-cleaning outer pane
- Frame colours: anthracite, black, white or RAL
- Insulated kerb or timber upstand built to suit
- Integral or fitted blinds
- Plastered or lined internal reveal
- Inner pane laminated for safety overhead
- Slim sightlines from inside — mostly glass, little frame
Before you order: points to check
- New openings in an existing roof need a structural check on joists
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Do you need permission in Pontardawe?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. 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.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. 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.

Common questions
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
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.
Is the survey in Pontardawe free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Pontardawe?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
