How we approach flat rooflights in Pembroke Dock
Thinking about flat rooflights in Pembroke Dock? The short answer: fixed double or triple glazed rooflights for flat roofs and extensions. The longer answer depends on your roof, which is why we survey before we price.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. In Pembroke Dock, as anywhere, flat rooflights are the usual choice for landings, bathrooms and rear extensions with flat roofs.
Pembroke Dock is around 54 km from Llanelli, and we survey and fit throughout that part of Dyfed, including the SA72 district.
Options we can specify in Pembroke Dock
- Solar-control or self-cleaning outer pane
- Rain sensor if paired with an opening unit
- Double or triple glazing
- Frame colours: anthracite, black, white or RAL
- Insulated kerb or timber upstand built to suit
- Slim sightlines from inside — mostly glass, little frame
- Double or triple glazed with a warm-edge spacer
What to check first
- The roof membrane must be dressed up the upstand before the unit goes on
- New openings in an existing roof need a structural check on joists
Consents for flat rooflights in Pembroke Dock
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. 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.

Questions about flat rooflights in Pembroke Dock
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.
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.
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.
Will I need planning permission in Pembroke Dock?
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.
Can you work alongside my builder in Pembroke Dock?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
