What do walk-on rooflights involve?
Walk-on rooflights in Clwyd means structural glass you can stand on, set flush into terraces and floors. Every quote follows a survey of the roof and the room below.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass.

Planning and building rules in Wales
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

How the job runs

- 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
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.
Can it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
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 I need planning permission in Clwyd?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed.
