How we approach bespoke & shaped rooflights in Caernarfon
We handle bespoke & shaped rooflights across Gwynedd, including Caernarfon. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. In Caernarfon, as anywhere, bespoke & shaped rooflights are the usual choice for openings that standard sizes do not fit.
Caernarfon sits about 13 km from Llangefni and 13 km from Bangor, Gwynedd, and we cover the whole LL55 postcode district and the roads in between.

Planning, building control and Caernarfon
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
