Hinged roof access rooflights for Derry/Londonderry: the essentials
We handle hinged roof access rooflights across County Londonderry, including Derry/Londonderry. In short: hinged glazed hatches over a stair or ladder for roof terrace access. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Think of hinged roof access rooflights for occasional roof access that also lights the stair.
We cover all of Derry/Londonderry and the BT48 district, and nearby Strabane and Limavady.

Planning, building control and Derry/Londonderry
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. Extensions follow a 25% glazing allowance in Technical Booklet F1.
