Walk-on rooflights in Egham: what is involved?
We handle walk-on rooflights across Surrey, including Egham. 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
Neighbouring towns include Staines (3 km) and Ashford, Surrey (7 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Fixed or with privacy interlayer
- Heated or self-cleaning glass on some ranges
- Anti-slip frit or etched top surface
- Double or triple glazed with a structural top pane
- Internal floor panels between storeys
- Flush with paving or decking — no trip edge
- Light below without losing usable terrace space
What to check first
- Drainage around the unit needs planning so water does not pond on the glass
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Do you need permission in Egham?
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. 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.
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.

Walk-on rooflights in Egham: 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.
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.
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.

Yes for new installations. Repair visits are charged, and we tell you the price before we book.
