How we approach walk-on rooflights in Thamesmead
Our walk-on rooflights service in Thamesmead covers structural glass you can stand on, set flush into terraces and floors. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for walk-on rooflights include terraces where the light below matters as much as the space above.
Jobs in Thamesmead 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.

Things we check at survey

Planning, building control and Thamesmead
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.
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.

Walk-on rooflights in Thamesmead: 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.
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.

Yes. We survey and fit walk-on rooflights in Thamesmead and across Greater London. Send your postcode and we will offer a survey date when we reply.
