Walk-on rooflights for Chippenham: the essentials
Our walk-on rooflights service in Chippenham 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. In Chippenham, as anywhere, walk-on rooflights are the usual choice for roof terraces, balconies and floors above basements.
We work across Wiltshire, including Chippenham, and in neighbouring towns such as Melksham and Devizes. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Integrated in paving pedestals or a timber deck
- Internal floor panels between storeys
- Anti-slip frit or etched top surface
- Fixed or with privacy interlayer
- Heated or self-cleaning glass on some ranges
- Pairs with a sliding box unit for terrace access
- Designed to a stated load rating
Things we check at survey
- 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 Chippenham
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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.
Is the survey in Chippenham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Chippenham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
