What do walk-on rooflights in Portslade involve?
For Portslade homes and buildings we offer walk-on rooflights: structural glass you can stand on, set flush into terraces and floors. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for walk-on rooflights include roof terraces, balconies and floors above basements.
We work across East Sussex, including Portslade, and in neighbouring towns such as Hove and Brighton. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Fixed or with privacy interlayer
- Internal floor panels between storeys
- Heated or self-cleaning glass on some ranges
- Double or triple glazed with a structural top pane
- Anti-slip frit or etched top surface
- Anti-slip finish on the walking surface
- Pairs with a sliding box unit for terrace access
What to check first
- 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
Do you need permission in Portslade?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about walk-on rooflights in Portslade
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.
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 I need planning permission in Portslade?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
How do I book a survey in Portslade?
