How we approach walk-on rooflights in Brighton
We handle walk-on rooflights across East Sussex, including Brighton. In short: structural glass you can stand on, set flush into terraces and floors. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Walk-on rooflights suit terraces where the light below matters as much as the space above.
Brighton is the main town we list in East Sussex; we also cover nearby Hove and Portslade.
Choices for your Brighton project
- Double or triple glazed with a structural top pane
- Fixed or with privacy interlayer
- Internal floor panels between storeys
- Anti-slip frit or etched top surface
- Heated or self-cleaning glass on some ranges
- Pairs with a sliding box unit for terrace access
- Designed to a stated load rating
Before you order: points to check
- Drainage around the unit needs planning so water does not pond on the glass
- Regular cleaning keeps the anti-slip finish effective
Planning, building control and Brighton
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about walk-on rooflights in Brighton
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.
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.
How much weight can a walk-on rooflight take?
It depends on the model and size. Manufacturers state a design imposed load for each unit; we only specify a unit whose rating suits the use, such as a private terrace or a busier area.
Do you fit walk-on rooflights in Brighton?
Yes. We survey and fit walk-on rooflights in Brighton and across East Sussex. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Brighton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
