What do sliding rooflights in Carrickfergus involve?
For Carrickfergus homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. 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 sliding rooflights for staircases that rise to a roof terrace.
From Carrickfergus to Newtownabbey, Bangor, County Down and Belfast, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Integrated balustrade on some ranges
- Anthracite, black or RAL frames
- Rain sensor
- Box (glazed sides) or flat sliding lid
- Electric drive with safety edge
- Electric operation with safety stops
- Lockable from inside
Before you order: points to check
- Needs space on the roof for the lid to slide clear
- Electric units need a dedicated supply and commissioning
Consents for sliding rooflights in Carrickfergus
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.
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. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
Can you work alongside my builder in Carrickfergus?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Carrickfergus?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
