What do pitched roof windows in Belfast involve?
For Belfast homes and buildings we offer pitched roof windows: centre-pivot and top-hung skylights for tiled and slate roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. In Belfast, as anywhere, pitched roof windows are the usual choice for pitched roofs over bedrooms, stairs and bathrooms.
Belfast is the main town we list in County Antrim; we also cover nearby Castlereagh and Newtownabbey.
What you can choose
- Flashings for tiles, slates or recessed fitting
- Integral blinds and shutters
- Combination and stacked windows
- Manual, electric or solar-powered opening
- Centre-pivot or top-hung
- Centre-pivot opening for easy cleaning from inside

Before you order: points to check
- Insulation collars and vapour control must be detailed
- Rafters may need trimming for wider windows
Do you need permission in Belfast?
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall. Listed buildings also need listed building consent from the council.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Pitched roof windows in Belfast: questions
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
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.
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
Do you fit pitched roof windows in Belfast?
Yes. We survey and fit pitched roof windows in Belfast and across County Antrim. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Belfast?
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls.
