What do pitched roof windows in Llangefni involve?
Thinking about pitched roof windows in Llangefni? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Think of pitched roof windows for pitched roofs over bedrooms, stairs and bathrooms.

Do you need permission in Llangefni?
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.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Will it need building regulations approval?
Fitting a new roof window usually involves cutting rafters and changing the thermal envelope, so building control approval (or, in England and Wales, a competent-person route) is normally needed. We tell you which applies.
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
Will I need planning permission in Llangefni?
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.
Do I need to be at home for the survey in Llangefni?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
