Roof lanterns in Coleraine: what is involved?
For Coleraine homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. Think of roof lanterns for orangeries, kitchen-diners and single-storey extensions.
From Coleraine to Limavady, Ballymena and Magherafelt, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Coleraine
- Aluminium or uPVC systems
- Solar-control or self-cleaning glass
- Rectangular, square or bespoke sizes
- Internal and external colours
- Opening vents with electric control
- Classic look that suits period and modern homes
- Light from every angle across the day
Things we check at survey
- Plaster-box depth affects how the lantern looks from below
- Larger lanterns may need a steel or timber ring beam
Consents for roof lanterns in Coleraine
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. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. Extensions follow a 25% glazing allowance in Technical Booklet F1.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about roof lanterns in Coleraine
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Can you work alongside my builder in Coleraine?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Coleraine?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage.
