Skylight replacement for Dungannon: the essentials
We handle skylight replacement across County Tyrone, including Dungannon. 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.
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.
Dungannon sits about 6 km from Coalisland and 16 km from Cookstown, and we cover the whole BT70 postcode district and the roads in between.
Specification options
- Dome to flat glass upgrade
- Roof window replacement in pitched roofs
- Misted glass unit replacement only

Things we check at survey
- Old glass and domes are disposed of responsibly
- Enlarging the opening changes the structure and may need approval
Planning and building rules for Dungannon
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. Listed buildings also need listed building consent from the council.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. Extensions follow a 25% glazing allowance in Technical Booklet F1.
See our building regulations guide for U-values, glazing limits and self-certification.

Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
