Where a roof lantern works best
A roof lantern sits on a flat roof and draws daylight down into the room below. They are most at home over kitchen extensions, orangeries and garden rooms, where a run of spotlights cannot match the effect of a glazed opening to the sky.
The size and position matter more than the style. Centre the lantern over the part of the room you use most — a dining table or kitchen island — and check the proportions from inside: a lantern that is too small for the roof can look lost, while an oversized one can dominate the ceiling.
Roof lanterns, skylights and heat
People often ask whether roof lanterns lose heat. A modern lantern uses thermally broken frames and sealed double glazing, so its thermal performance is specified like any other glazed product — compare the quoted glass and frame specifications rather than assuming all lanterns are equal.
Skylights and roof windows are the simpler alternative: a single glazed unit set into the roof slope or flat roof. For a pitched roof, a roof window may suit better than a lantern; for a flat roof over an extension, a lantern makes more of the ceiling. Our roof lanterns explained guide covers the terminology, and the orangeries page shows lanterns in context.
Lantern roof cost and installation
Lantern roof cost depends on the size, the frame system, the glass specification and the work to the roof itself — the upstand or kerb the lantern sits on has to be built and weathered correctly. Installation is planned so the room below is weathertight throughout.

Frequently Asked Questions
Do roof lanterns leak?
Properly installed, modern roof lanterns are fully weatherproof. We guarantee all our installations.
Do roof lanterns lose heat?
A modern lantern with thermally broken frames and sealed double glazing performs to its quoted specification. Compare the glass and frame details in the written quote rather than assuming all lanterns are equal.
Can a roof lantern be fitted to an existing flat roof?
Often yes, provided the roof structure can carry it and a suitable upstand can be formed. The survey assesses the roof before any design is proposed.
What is the difference between a roof lantern and a skylight?
A lantern is a raised glazed structure, usually with a pitched glazed roof of its own, sitting on an upstand. A skylight or roof window is a single glazed unit set into the roof surface.
Do roof lanterns need planning permission?
A lantern on an existing flat roof is often straightforward, but new extensions, listed buildings and conservation areas have their own rules. Check with your local planning authority where that applies.
