How we approach roof lanterns in Deeside
Thinking about roof lanterns in Deeside? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Think of roof lanterns for rooms that need height as well as light.
Deeside sits about 2 km from Hawarden and 5 km from Buckley, and we cover the whole CH5 postcode district and the roads in between.

Planning and building rules for Deeside
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.
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.

Roof lanterns in Deeside: questions
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Will I need planning permission in Deeside?
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.
Can you work alongside my builder in Deeside?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
