What do walk-on rooflights in Havant involve?
Thinking about walk-on rooflights in Havant? 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. In Havant, as anywhere, walk-on rooflights are the usual choice for roof terraces, balconies and floors above basements.
We work across Hampshire, including Havant, and in neighbouring towns such as Waterlooville and Portsmouth. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Havant project
- Fixed or with privacy interlayer
- Double or triple glazed with a structural top pane
- Anti-slip frit or etched top surface
- Internal floor panels between storeys
- Integrated in paving pedestals or a timber deck
- Can also be used internally between floors
- Flush with paving or decking — no trip edge
What to check first
- Drainage around the unit needs planning so water does not pond on the glass
- Structural support and the design load must be confirmed by the manufacturer or an engineer
Do you need permission in Havant?
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.
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.

Questions about walk-on rooflights in Havant
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.
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.
Will I need planning permission in Havant?
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.
Can you work alongside my builder in Havant?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
