Walk-on rooflights for Thatcham: the essentials
Walk-on rooflights in Thatcham means structural glass you can stand on, set flush into terraces and floors. We cover the RG18 district and the rest of Berkshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of walk-on rooflights for roof terraces, balconies and floors above basements.
Thatcham is around 21 km from Reading, and we survey and fit throughout that part of Berkshire, including the RG18 district.

Planning and building rules for Thatcham
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. 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
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.
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.
Is the survey in Thatcham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Thatcham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
