Walk-on rooflights in Lisburn: what is involved?
We handle walk-on rooflights across County Antrim, including Lisburn. In short: structural glass you can stand on, set flush into terraces and floors. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
Jobs in Lisburn are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Lisburn
- Integrated in paving pedestals or a timber deck
- Anti-slip frit or etched top surface
- Fixed or with privacy interlayer
- Internal floor panels between storeys
- Double or triple glazed with a structural top pane
- Flush with paving or decking — no trip edge
- Pairs with a sliding box unit for terrace access
Things we check at survey
- Drainage around the unit needs planning so water does not pond on the glass
- Structural support and the design load must be confirmed by the manufacturer or an engineer
Consents for walk-on rooflights in Lisburn
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. Extensions follow a 25% glazing allowance in Technical Booklet F1.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can you see through it?
Clear glass can be seen through from both sides. A privacy interlayer or patterned frit keeps the light while obscuring the view.
Is the glass slippery?
Walk-on glass has an anti-slip finish, usually a ceramic frit or etched pattern. Like any outdoor surface it needs cleaning to stay effective.
Will it sit flush with my paving?
Yes — the unit is set on its own upstand so the glass finishes level with the surrounding paving or decking.
Will I need planning permission in Lisburn?
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.
Can you work alongside my builder in Lisburn?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
