How we approach walk-on rooflights in East Grinstead
Thinking about walk-on rooflights in East Grinstead? The short answer: structural glass you can stand on, set flush into terraces and floors. The longer answer depends on your roof, which is why we survey before we price.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Walk-on rooflights suit roof terraces, balconies and floors above basements.
East Grinstead sits about 12 km from Horley and 12 km from Crawley, and we cover the whole RH19 postcode district and the roads in between.
Specification options
- Heated or self-cleaning glass on some ranges
- Double or triple glazed with a structural top pane

What to check first
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
- Regular cleaning keeps the anti-slip finish effective
Planning and building rules for East Grinstead
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.

Walk-on rooflights in East Grinstead: 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.
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 it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
