What do walk-on rooflights in Northolt involve?
For Northolt 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.
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. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
Northolt is around 17 km from central London, and we survey and fit throughout that part of Greater London, including the UB5 district.
Options we can specify in Northolt
- Fixed or with privacy interlayer
- Anti-slip frit or etched top surface
- Double or triple glazed with a structural top pane
- Integrated in paving pedestals or a timber deck
- Internal floor panels between storeys
- Anti-slip finish on the walking surface
- Pairs with a sliding box unit for terrace access
What to check first
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Planning and building rules for Northolt
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about walk-on rooflights in Northolt
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.
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.
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.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
