How we approach flat rooflights in Abergavenny
Thinking about flat rooflights in Abergavenny? 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 Abergavenny, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
Neighbouring towns include Pontypool (13 km) and Ebbw Vale (14 km). We offer a survey date when we reply to your enquiry.
Specification options
- Square, rectangular or long-format sizes

Things we check at survey
- The roof membrane must be dressed up the upstand before the unit goes on
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Do you need permission in Abergavenny?
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.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
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.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
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 Abergavenny?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Abergavenny free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
