What do roof lanterns in Tottenham involve?
Our roof lanterns service in Tottenham covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written 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 orangeries, kitchen-diners and single-storey extensions.
We work across Greater London, including Tottenham, and in neighbouring towns such as Edmonton and Wood Green. Access, parking and how the glass reaches the roof are all checked at the survey.

Things we check at survey
- Some designs project above the roof enough to affect planning on certain houses
- Plaster-box depth affects how the lantern looks from below
Planning, building control and Tottenham
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

The process, step by step
- Tell us what you have. Send the N17 postcode, a rough size and a couple of photos.

- Installation day. Usually one day into a prepared opening, longer for new openings.

Questions about roof lanterns in Tottenham
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 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.
Will I need planning permission in Tottenham?
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.
Do I need to be at home for the survey in Tottenham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
