Pitched roof windows in Dolgellau: what is involved?
Thinking about pitched roof windows in Dolgellau? 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.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Dolgellau, as anywhere, pitched roof windows are the usual choice for lofts, attic rooms, landings and vaulted ceilings.
Jobs in Dolgellau 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.
Specification options
- Integral blinds and shutters
- Centre-pivot or top-hung
- Double or triple glazing
- Manual, electric or solar-powered opening

Before you order: points to check
- Escape-window rules can apply to loft rooms
- Front-facing roof windows can need permission in conservation areas
Consents for pitched roof windows in Dolgellau
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
