What do walk-on rooflights in Horley involve?
Our walk-on rooflights service in Horley 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for walk-on rooflights include terraces where the light below matters as much as the space above.
From Horley to Crawley, Redhill and Reigate, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Double or triple glazed with a structural top pane
- Fixed or with privacy interlayer
- Internal floor panels between storeys
- Heated or self-cleaning glass on some ranges
- Anti-slip frit or etched top surface
- Pairs with a sliding box unit for terrace access
- Flush with paving or decking — no trip edge
Things we check at survey
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
- Structural support and the design load must be confirmed by the manufacturer or an engineer
Planning and building rules for Horley
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. 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.

Questions about walk-on rooflights in Horley
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.
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.
Is the survey in Horley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Horley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
