Walk-on rooflights in Andover: what is involved?
Thinking about walk-on rooflights in Andover? 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
We work across Hampshire, including Andover, and in neighbouring towns such as Winchester and Newbury. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Heated or self-cleaning glass on some ranges
- Fixed or with privacy interlayer
- Anti-slip frit or etched top surface
- Integrated in paving pedestals or a timber deck
- Internal floor panels between storeys
- Anti-slip finish on the walking surface
- Pairs with a sliding box unit for terrace access
Before you order: points to check
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Planning, building control and Andover
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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.
Do I need to be at home for the survey in Andover?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Andover?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
