Walk-on rooflights in Gloucester: what is involved?
We handle walk-on rooflights across Gloucestershire, including Gloucester. 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
We cover all of Gloucester and the GL1 district, and nearby Cheltenham and Stroud.
What you can choose
- Integrated in paving pedestals or a timber deck
- Internal floor panels between storeys
- Anti-slip frit or etched top surface
- Heated or self-cleaning glass on some ranges
- Double or triple glazed with a structural top pane
- Pairs with a sliding box unit for terrace access
- 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
Planning, building control and Gloucester
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.
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. 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.
Read the planning permission guide before you commit to a design.

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