What do bespoke & shaped rooflights in Belfast involve?
For Belfast homes and buildings we offer bespoke & shaped rooflights: triangular, angled, curved and multi-pane rooflights made to measure. 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, bespoke & shaped rooflights are the usual choice for openings that standard sizes do not fit.
Belfast is the main town we list in County Antrim; we also cover nearby Castlereagh and Newtownabbey.

- Sloped or monopitch rooflights

Consents for bespoke & shaped rooflights 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. Listed buildings also need listed building consent from the council.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Common questions
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can you work alongside my builder in Belfast?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you offer bespoke & shaped rooflights in Belfast?
Yes. We carry out bespoke & shaped rooflights in Belfast and across County Antrim. Send your postcode and we will offer a survey date when we reply.
