How we approach walk-on rooflights in Kilburn
We handle walk-on rooflights across Greater London, including Kilburn. 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.
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. Think of walk-on rooflights for roof terraces, balconies and floors above basements.
Neighbouring towns include Hampstead (1 km) and Cricklewood (2 km). We offer a survey date when we reply to your enquiry.

Consents for walk-on rooflights in Kilburn
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.
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.

Walk-on rooflights in Kilburn: questions
Can it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
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.
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.
Do I need to be at home for the survey in Kilburn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Kilburn free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
