What do walk-on rooflights in Farnham involve?
Thinking about walk-on rooflights in Farnham? 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Walk-on rooflights suit terraces where the light below matters as much as the space above.
Farnham is around 20 km from Woking, and we survey and fit throughout that part of Surrey, including the GU9 district.
Choices for your Farnham project
- Integrated in paving pedestals or a timber deck
- Heated or self-cleaning glass on some ranges
- Internal floor panels between storeys
- Anti-slip frit or etched top surface
- Fixed or with privacy interlayer
- Anti-slip finish on the walking surface
- Flush with paving or decking — no trip edge
Before you order: points to check
- Regular cleaning keeps the anti-slip finish effective
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Do you need permission in Farnham?
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Questions about walk-on rooflights in Farnham
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 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.
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.
Do I need to be at home for the survey in Farnham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Farnham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
