How we approach walk-on rooflights in St Helens
Our walk-on rooflights service in St Helens 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 and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Typical uses for walk-on rooflights include roof terraces, balconies and floors above basements.
St Helens is around 17 km from Liverpool, and we survey and fit throughout that part of Merseyside, including the WA10 district.
What you can choose
- Double or triple glazed with a structural top pane
- Heated or self-cleaning glass on some ranges

- Fixed or with privacy interlayer
- Anti-slip frit or etched top surface
- Can also be used internally between floors
- Designed to a stated load rating
Before you order: points to check
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
- Regular cleaning keeps the anti-slip finish effective
Planning, building control and St Helens
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.

Common questions
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 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 St Helens?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
