What do walk-on rooflights in Melksham involve?
We handle walk-on rooflights across Wiltshire, including Melksham. 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 West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
Jobs in Melksham are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Melksham
- Heated or self-cleaning glass on some ranges
- Anti-slip frit or etched top surface
- Internal floor panels between storeys
- Double or triple glazed with a structural top pane
- Fixed or with privacy interlayer
- Anti-slip finish on the walking surface
- Light below without losing usable terrace space
Before you order: points to check
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Planning, building control and Melksham
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about walk-on rooflights in Melksham
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.
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.
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 you work alongside my builder in Melksham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Melksham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
