Walk-on rooflights for Bow: the essentials
We handle walk-on rooflights across Greater London, including Bow. In short: structural glass you can stand on, set flush into terraces and floors. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Think of walk-on rooflights for roof terraces, balconies and floors above basements.
We work across Greater London, including Bow, and in neighbouring towns such as Stratford and Hackney. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Fixed or with privacy interlayer
- Heated or self-cleaning glass on some ranges
- Internal floor panels between storeys
- Anti-slip frit or etched top surface
- Integrated in paving pedestals or a timber deck
- Can also be used internally between floors
- Pairs with a sliding box unit for terrace access
Before you order: points to check
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
- Drainage around the unit needs planning so water does not pond on the glass
Consents for walk-on rooflights in Bow
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about walk-on rooflights in Bow
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.
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.
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.
Do I need to be at home for the survey in Bow?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Bow?
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.
