How we approach walk-on rooflights in South Croydon
Our walk-on rooflights service in South Croydon covers structural glass you can stand on, set flush into terraces and floors. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. In South Croydon, as anywhere, walk-on rooflights are the usual choice for terraces where the light below matters as much as the space above.
We work across Greater London, including South Croydon, and in neighbouring towns such as Croydon and Purley. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in South Croydon
- Internal floor panels between storeys
- Fixed or with privacy interlayer
- Double or triple glazed with a structural top pane
- Integrated in paving pedestals or a timber deck
- Heated or self-cleaning glass on some ranges
- Can also be used internally between floors
- Flush with paving or decking — no trip edge
Before you order: points to check
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Drainage around the unit needs planning so water does not pond on the glass
Planning, building control and South Croydon
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
Read the planning permission guide before you commit to a design.

Walk-on rooflights in South Croydon: 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.
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.
Can you work alongside my builder in South Croydon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in South Croydon?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
