Walk-on rooflights for Welling: the essentials
We handle walk-on rooflights across Greater London, including Welling. 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.
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. Walk-on rooflights suit roof terraces, balconies and floors above basements.
We work across Greater London, including Welling, and in neighbouring towns such as Bexleyheath and Bexley. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Double or triple glazed with a structural top pane
- Internal floor panels between storeys
- Integrated in paving pedestals or a timber deck
- Heated or self-cleaning glass on some ranges
- Anti-slip frit or etched top surface
- Flush with paving or decking — no trip edge
- Can also be used internally between floors
Things we check at survey
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Regular cleaning keeps the anti-slip finish effective
Planning, building control and Welling
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. 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.
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. 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 Welling: 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.
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.
Is the survey in Welling 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 Welling?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
