Skylight replacement in Newtownabbey: what is involved?
We handle skylight replacement across County Antrim, including Newtownabbey. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
We work across County Antrim, including Newtownabbey, and in neighbouring towns such as Belfast and Carrickfergus. Access, parking and how the glass reaches the roof are all checked at the survey.

Before you order: points to check

Planning, building control and Newtownabbey
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight replacement in Newtownabbey: questions
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Will I need planning permission in Newtownabbey?
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.
Can you work alongside my builder in Newtownabbey?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
