Skylight replacement in Cookstown: what is involved?
For Cookstown homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Skylight replacement suits older extensions due a modern rooflight.
Cookstown sits about 12 km from Coalisland and 15 km from Magherafelt, and we cover the whole BT80 postcode district and the roads in between.
Options we can specify in Cookstown
- Like-for-like size replacement
- Dome to flat glass upgrade
- Misted glass unit replacement only
- Upstand rebuild and insulation
- Fixed to electric opening
- Often reuses the existing opening
- Clearer view and more light
Things we check at survey
- A replacement is a chance to meet current thermal standards
- Upstand and roof condition decide the scope
Do you need permission in Cookstown?
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. 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. 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.

Questions about skylight replacement in Cookstown
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.
Can you work alongside my builder in Cookstown?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Cookstown free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
