What are conservation rooflights?
Across County Londonderry, our conservation rooflights work covers slim, low-profile steel-look rooflights for period and listed roofs. Survey first, fixed price second, fitting third.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting.

Planning and building rules in Northern Ireland
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.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. Extensions follow a 25% glazing allowance in Technical Booklet F1.
