What do ridge & pitched glass roofs in Caernarfon involve?
Our ridge & pitched glass roofs service in Caernarfon covers dual-pitch glazed roofs for side returns, links and long extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for ridge & pitched glass roofs include terraced-house side returns that would otherwise be dark.
Caernarfon is around 13 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL55 district.

What to check first
- Overheating is a real risk on south-facing glass roofs
- Large glass roofs affect the energy calculation for the extension
Planning and building rules for Caernarfon
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.
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about ridge & pitched glass roofs in Caernarfon
Will it be noisy in the rain?
Glass is quieter than polycarbonate. Triple glazing or laminated glass reduces rain noise further.
Can it have opening vents?
Yes, top-hung vents with electric actuators are common, often with a rain sensor.
Is a glass roof too hot for a kitchen?
Without care, it can be. Solar-control glass, an opening vent at the top and a blind make a south-facing glass roof comfortable.
