Roof lanterns for Hampton: the essentials
Thinking about roof lanterns in Hampton? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Roof lanterns suit rooms that need height as well as light.
We work across Greater London, including Hampton, and in neighbouring towns such as Sunbury-on-Thames and Walton-on-Thames. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Aluminium or uPVC systems
- Opening vents with electric control
- LED lighting in the plaster box
- Internal and external colours
- Rectangular, square or bespoke sizes
- Can include opening vents
- Slim aluminium bars, more glass
What to check first
- Plaster-box depth affects how the lantern looks from below
- Larger lanterns may need a steel or timber ring beam
Consents for roof lanterns in Hampton
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
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.

Roof lanterns in Hampton: questions
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.
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.
Do you fit roof lanterns in Hampton?
Yes. We survey and fit roof lanterns in Hampton and across Greater London. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Hampton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
