Gable roof lantern cost

How much does a gable roof lantern cost? That depends on how it is built. A gable roof lantern has two glass panes that meet at the ridge. That gives a classic look and light from two sides. There is more to it than a mono-pitch: two glass panes, a ridge profile and drainage along both long sides. That is why the price starts at €2,399.

For an open-plan kitchen or a large extension in the middle of the roof, this is often the type that brings in the most light. See a roof lantern above the kitchen for how that works in practice.

Length and width per roof slope

As standard, a gable roof lantern goes up to 6 metres long and 4 metres wide per slope. Within those limits, length is the biggest price factor, because every extra metre means double the extra glass, extra ridge profile and extra bottom rail.

If it needs to be larger, we build modularly. The roof lantern then consists of sections that are coupled on site. That takes more profiles and coupling work, but keeps the panels manageable. Also read with or without a glazing bar for the trade-off between large panels and a divided layout.

• Up to 6 metres long in the standard version
• Up to 4 metres wide per roof slope
• Larger: built modularly and coupled

Symmetric or asymmetric

On a symmetric gable roof lantern, the ridge sits exactly in the middle and both slopes are equal. On an asymmetric one, the ridge is off centre. That may be needed if the roof lantern runs up against an obstacle or if you want to direct the light to one side.

Asymmetric means two different glass sizes. It is just as much made to measure, but the drawing and production are a bit more involved. Unsure about the type? Mono-pitch or gable and gable or hipped will help you decide.

Drainage and what the price includes

The bottom rails contain a self-cleaning drainage system. Water runs to your existing gutter or downpipe, so you do not need a separate gutter on the roof lantern. HR++ double glazing is standard, and you can choose triple glazing, solar control or obscure glass as options.

• Two glass panes with a ridge profile
• Self-cleaning drainage in the bottom rails
• Connection to existing gutter or downpipe
• Aluminium frame in any RAL colour
