Walk-on rooflights for Eltham: the essentials
Walk-on rooflights in Eltham means structural glass you can stand on, set flush into terraces and floors. We cover the SE9 district and the rest of Greater London, with a survey before any price is fixed.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Walk-on rooflights suit terraces where the light below matters as much as the space above.
Jobs in Eltham are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Integrated in paving pedestals or a timber deck
- Anti-slip frit or etched top surface
- Internal floor panels between storeys
- Double or triple glazed with a structural top pane
- Heated or self-cleaning glass on some ranges
- Flush with paving or decking — no trip edge
- Anti-slip finish on the walking surface
Before you order: points to check
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
- Structural support and the design load must be confirmed by the manufacturer or an engineer
Planning, building control and Eltham
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. 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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Questions about walk-on rooflights in Eltham
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.
Will I need planning permission in Eltham?
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.
Is the survey in Eltham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
