Walk-on rooflights for Greenford: the essentials
For Greenford 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Walk-on rooflights suit roof terraces, balconies and floors above basements.
Neighbouring towns include Northolt (2 km) and Southall (2 km). We offer a survey date when we reply to your enquiry.
Specification options
- 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
- Internal floor panels between storeys
- Fixed or with privacy interlayer
- Flush with paving or decking — no trip edge
- Pairs with a sliding box unit for terrace access
What to check first
- 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
Do you need permission in Greenford?
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. 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.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Walk-on rooflights in Greenford: questions
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.
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.
Do I need to be at home for the survey in Greenford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Greenford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
