How we approach sliding rooflights in Coleraine
For Coleraine 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.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. In Coleraine, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
Coleraine sits about 20 km from Limavady and 39 km from Ballymena, and we cover the whole BT51 postcode district and the roads in between.
Choices for your Coleraine project

- Anthracite, black or RAL frames

Before you order: points to check

Consents for sliding rooflights 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.

Questions about sliding rooflights in Coleraine
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.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Is the survey in Coleraine free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
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.
