Walk-on rooflights for Feltham: the essentials
For Feltham 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Feltham, as anywhere, walk-on rooflights are the usual choice for terraces where the light below matters as much as the space above.
Feltham is around 21 km from central London, and we survey and fit throughout that part of Greater London, including the TW13 district.
Options we can specify in Feltham
- Heated or self-cleaning glass on some ranges
- Integrated in paving pedestals or a timber deck
- Fixed or with privacy interlayer
- Double or triple glazed with a structural top pane
- Internal floor panels between storeys
- Pairs with a sliding box unit for terrace access
- Designed to a stated load rating
Things we check at survey
- 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
Planning, building control and Feltham
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. 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.

Walk-on rooflights in Feltham: 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.
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 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 survey in Feltham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Feltham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
