Roof lanterns for Limavady: the essentials
Our roof lanterns service in Limavady covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
Limavady sits about 20 km from Coleraine and 24 km from Derry/Londonderry, and we cover the whole BT49 postcode district and the roads in between.

Planning and building rules for Limavady
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.
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.

Common questions
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Can you work alongside my builder in Limavady?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit roof lanterns in Limavady?
Yes. We survey and fit roof lanterns in Limavady and across County Londonderry. Send your postcode and we will offer a survey date when we reply.
