Dome rooflight replacement in County Armagh

A good share of dome rooflight replacement in County Armagh is replacement work. Older units go brittle or discoloured, sealed glass mists, and seals give up after years of sun and frost. Swapping the unit is often possible on the existing kerb, provided that kerb is sound, level and tall enough above the finished roof. Where it is not, we rebuild it. We cover the whole of County Armagh, across 8 postcode districts, with fitters travelling to each address.

Guide ranges for supply & fit, per dome; building control notice fee extra on homes in England and Wales. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.

What's included

  • Membrane checked where it meets the kerb, with small repairs made
  • Inside checked for drips and the trim refitted

  • Multi-skin domes and energy — We fit multi-skin domes rather than single-skin ones as replacements.
  • Kerb size and adaptors — We measure every kerb against the new dome's sizes.

Rules that apply in Northern Ireland

Northern Ireland's building regulations set a minimum of WER Band C or 1.6 W/m²K for rooflights and roof windows in existing homes, assessed under Technical Booklet F1. New openings involve trimming the roof structure, so expect a building control application. Many house rooflights don't need planning permission, but conservation areas and listed buildings are excluded, and side windows near a boundary have obscure-glazing rules. We confirm what applies.

Common questions in County Armagh

Do I need planning permission for a rooflight in County Armagh?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in Northern Ireland. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

Does a rooflight need building control approval?

In Northern Ireland a new opening alters the roof structure, so expect a building control application; confirm the position with your council, including for replacements. The new rooflight must meet WER Band C or 1.6 W/m²K. We confirm what applies before you commit.

How long does fitting take?

Fitting a dome rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
