Roof lanterns for Gravesend: the essentials
For Gravesend homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of roof lanterns for rooms that need height as well as light.
Gravesend sits about 5 km from Grays and 9 km from Strood, and we cover the whole DA12 postcode district and the roads in between.
What you can choose
- Rectangular, square or bespoke sizes
- Aluminium or uPVC systems
- Opening vents with electric control
- Internal and external colours
- LED lighting in the plaster box
- Slim aluminium bars, more glass
- Light from every angle across the day
What to check first
- Needs a strong, level kerb or upstand
- Some designs project above the roof enough to affect planning on certain houses
Do you need permission in Gravesend?
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.
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. 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.
Read the planning permission guide before you commit to a design.
What do roof lanterns cost in Gravesend?
These are typical supply-and-fit ranges. For an address in Gravesend, scaffold, a hoist for heavy glass, or a new structural opening can move the figure, which is why we survey first.

Questions about roof lanterns in Gravesend
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 roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Can you work alongside my builder in Gravesend?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Gravesend?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
