What do flat rooflights in Hawarden involve?
Flat rooflights in Hawarden means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the CH5 district and the rest of Clwyd, 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. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
Jobs in Hawarden 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
- Insulated kerb or timber upstand built to suit
- Square, rectangular or long-format sizes
- Plastered or lined internal reveal
- Frame colours: anthracite, black, white or RAL
- Double or triple glazing
- Slim sightlines from inside — mostly glass, little frame
- Inner pane laminated for safety overhead
Things we check at survey
- New openings in an existing roof need a structural check on joists
- The roof membrane must be dressed up the upstand before the unit goes on
Planning, building control and Hawarden
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.

Flat rooflights in Hawarden: 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.
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.
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 you work alongside my builder in Hawarden?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
