What are sliding rooflights?
Our sliding rooflights service in County Armagh covers box rooflights whose glass lid slides back for walk-out roof access. We survey every job before fixing the price.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass.

Planning and building rules in Northern Ireland
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. 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.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
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.
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.
Will I need planning permission in County Armagh?
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.
