Ridge & pitched glass roofs for Llangefni: the essentials
Our ridge & pitched glass roofs service in Llangefni 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.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Typical uses for ridge & pitched glass roofs include terraced-house side returns that would otherwise be dark.
Jobs in Llangefni 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
- Aluminium systems in standard and RAL colours
- Solar-control, self-cleaning or tinted glass
- Opening vents and electric actuators
- Integrated gutters and box gutters
- Dual-pitch or mono-pitch
- Forms the roof as well as the window
- Opening vents available
Before you order: points to check
- Large glass roofs affect the energy calculation for the extension
- Party-wall agreements may apply on terraced houses
Planning, building control and Llangefni
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.

Common questions
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.
Do I need a party wall agreement?
If the work affects a party wall or boundary, the Party Wall etc. Act 1996 may apply in England and Wales. We flag this at survey so you can serve notice in time.
