Walk-on rooflights in West Glamorgan: the essentials
Walk-on rooflights in West Glamorgan 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.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere.

Planning and building rules in Wales
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. 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.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
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.
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.
Do I need to be at home for the survey in West Glamorgan?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
