What does skylight replacement in Coleraine involve?
Thinking about skylight replacement in Coleraine? 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.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. Typical uses for skylight replacement include older extensions due a modern rooflight.

Planning and building rules for Coleraine
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.
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.

Skylight replacement in Coleraine: questions
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.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
Can you work alongside my builder in Coleraine?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Coleraine?
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.
