How we approach roof lanterns in South Croydon
We handle roof lanterns across Greater London, including South Croydon. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
South Croydon is around 16 km from central London, and we survey and fit throughout that part of Greater London, including the CR2 district.

Planning and building rules for South Croydon
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about roof lanterns in South Croydon
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Is the survey in South Croydon free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do you fit roof lanterns in South Croydon?
Yes. We survey and fit roof lanterns in South Croydon and across Greater London. Send your postcode and we will offer a survey date when we reply.
