How we approach walk-on rooflights in Didcot
For Didcot homes and buildings we offer walk-on rooflights: structural glass you can stand on, set flush into terraces and floors. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of walk-on rooflights for roof terraces, balconies and floors above basements.
Jobs in Didcot 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 Didcot
- Double or triple glazed with a structural top pane
- Heated or self-cleaning glass on some ranges
- Anti-slip frit or etched top surface
- Internal floor panels between storeys
- Fixed or with privacy interlayer
- Light below without losing usable terrace space
- Designed to a stated load rating
Things we check at survey
- 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
Do you need permission in Didcot?
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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.
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.
