Rooflight upstands & kerbs in Coleraine: what is involved?
We handle rooflight upstands & kerbs across County Londonderry, including Coleraine. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
We work across County Londonderry, including Coleraine, and in neighbouring towns such as Limavady and Ballymena. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Coleraine?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. Listed buildings also need listed building consent from the council.
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.
