How we approach walk-on rooflights in Catford
Our walk-on rooflights service in Catford covers structural glass you can stand on, set flush into terraces and floors. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
Catford sits about 2 km from Lewisham and 3 km from Blackheath, and we cover the whole SE6 postcode district and the roads in between.
Options we can specify in Catford
- Fixed or with privacy interlayer
- Anti-slip frit or etched top surface

Things we check at survey
- Drainage around the unit needs planning so water does not pond on the glass
- Regular cleaning keeps the anti-slip finish effective
Consents for walk-on rooflights in Catford
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.

Questions about walk-on rooflights in Catford
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.
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.
Do I need to be at home for the survey in Catford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
