What do walk-on rooflights involve?
Walk-on rooflights in East Sussex means structural glass you can stand on, set flush into terraces and floors. Every quote follows a survey of the roof and the room below.
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. Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice.

Planning and building rules in England
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Common questions
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.
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.
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.
Will I need planning permission in East Sussex?
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.
