Walk-on rooflights in South Glamorgan: the essentials
Our walk-on rooflights service in South Glamorgan covers structural glass you can stand on, set flush into terraces and floors. We survey every job before fixing the price.
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. 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
- 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
How much weight can a walk-on rooflight take?
It depends on the model and size. Manufacturers state a design imposed load for each unit; we only specify a unit whose rating suits the use, such as a private terrace or a busier area.
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.
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.
Do I need to be at home for the survey in South Glamorgan?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
