What do roof lanterns in Leatherhead involve?
We handle roof lanterns across Surrey, including Leatherhead. 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
From Leatherhead to Epsom, Ewell and Esher, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- LED lighting in the plaster box
- Rectangular, square or bespoke sizes
- Opening vents with electric control
- Solar-control or self-cleaning glass
- Aluminium or uPVC systems
- Light from every angle across the day

Things we check at survey
- Some designs project above the roof enough to affect planning on certain houses
- Larger lanterns may need a steel or timber ring beam
Planning and building rules for Leatherhead
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Roof lanterns in Leatherhead: questions
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.
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
