How we approach walk-on rooflights in Epsom
Thinking about walk-on rooflights in Epsom? 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
From Epsom to Ewell, Banstead and Leatherhead, the same survey-first process applies: measure, specify, fix the price, then fit.

- Anti-slip frit or etched top surface
- Can also be used internally between floors

What to check first
- Regular cleaning keeps the anti-slip finish effective
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Planning and building rules for Epsom
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. 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 Epsom: 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.
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.
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 work alongside my builder in Epsom?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Epsom free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
