How we approach walk-on rooflights in St Austell
Our walk-on rooflights service in St Austell 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.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Typical uses for walk-on rooflights include terraces where the light below matters as much as the space above.
From St Austell to Bodmin, Truro and Newquay, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Anti-slip frit or etched top surface
- Fixed or with privacy interlayer

- Anti-slip finish on the walking surface

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
Do you need permission in St Austell?
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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 it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
Can you work alongside my builder in St Austell?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in St Austell?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
