What are walk-on rooflights?
Across County Londonderry, our walk-on rooflights work covers structural glass you can stand on, set flush into terraces and floors. Survey first, fixed price second, fitting third.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

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.
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.
Does it need a structural engineer?
Often, yes. Where the unit sits on new or altered structure, an engineer confirms the support and the manufacturer confirms the glass.
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.
Do I need to be at home for the survey in County Londonderry?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
