Skylight replacement for Armagh: the essentials
Thinking about skylight replacement in Armagh? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. In Armagh, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Armagh sits about 11 km from Keady and 17 km from Portadown, and we cover the whole BT60 postcode district and the roads in between.

Planning and building rules for Armagh
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. 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. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.
Read the planning permission guide before you commit to a design.

Skylight replacement in Armagh: questions
Do I need building regulations approval to replace a rooflight?

How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.

Is the survey in Armagh free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
