Walk-on rooflights for Truro: the essentials
We handle walk-on rooflights across Cornwall, including Truro. 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.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Walk-on rooflights suit roof terraces, balconies and floors above basements.
We cover all of Truro and the TR1 district, and nearby Falmouth and Redruth.
Options we can specify in Truro
- Internal floor panels between storeys
- Fixed or with privacy interlayer
- Anti-slip frit or etched top surface
- Integrated in paving pedestals or a timber deck
- Heated or self-cleaning glass on some ranges
- Anti-slip finish on the walking surface
- Pairs with a sliding box unit for terrace access
What to check first
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Drainage around the unit needs planning so water does not pond on the glass
Planning and building rules for Truro
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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 Truro: 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.
How do I book a survey in Truro?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Truro?
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.
