Walk-on rooflights for Caterham: the essentials
We handle walk-on rooflights across Surrey, including Caterham. 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.
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.
Jobs in Caterham are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Fixed or with privacy interlayer
- Internal floor panels between storeys
- Heated or self-cleaning glass on some ranges
- Double or triple glazed with a structural top pane
- Anti-slip frit or etched top surface
- Flush with paving or decking — no trip edge
- Designed to a stated load rating
Before you order: points to check
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Drainage around the unit needs planning so water does not pond on the glass
Planning and building rules for Caterham
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Walk-on rooflights in Caterham: questions
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.
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.
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 Caterham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
