Sliding rooflights in Downpatrick: what is involved?
Our sliding rooflights service in Downpatrick covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
Downpatrick sits about 29 km from Castlereagh and 29 km from Newtownards, and we cover the whole BT30 postcode district and the roads in between.

What to check first

Consents for sliding rooflights in Downpatrick
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. Listed buildings also need listed building consent from the council.

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.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Do I need to be at home for the survey in Downpatrick?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
