Walk-on rooflights for Harwich: the essentials
Walk-on rooflights in Harwich means structural glass you can stand on, set flush into terraces and floors. We cover the CO12 district and the rest of Essex, with a survey before any price is fixed.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. In Harwich, as anywhere, walk-on rooflights are the usual choice for roof terraces, balconies and floors above basements.
We work across Essex, including Harwich, and in neighbouring towns such as Felixstowe and Ipswich. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Internal floor panels between storeys
- Anti-slip frit or etched top surface
- Integrated in paving pedestals or a timber deck
- Heated or self-cleaning glass on some ranges
- Double or triple glazed with a structural top pane
- Light below without losing usable terrace space
- Flush with paving or decking — no trip edge
Things we check at survey
- Drainage around the unit needs planning so water does not pond on the glass
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Do you need permission in Harwich?
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. 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.

Walk-on rooflights in Harwich: 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.
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.
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 Harwich?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
