A Guide To Lantern Roofs

Lantern roofs have become increasingly popular in modern home design due to their ability to enhance natural light, provide an aesthetic focal point, and create a sense of spaciousness. 

Whether you’re admiring the stars on a cloudless evening or basking in the sun’s comforting rays during daylight hours, lantern roofs seamlessly integrate the ever-shifting wonders of the external world into your indoor environment. They offer uninterrupted glimpses of the sky, fostering a profound connection with the natural world.

In this comprehensive guide, we will explore the world of lantern roofs, answering common questions and providing valuable information to help you make an informed decision.

What is a lantern roof?

A lantern roof, also known as a roof lantern or skylight lantern, is a type of architectural feature that is installed on a flat or pitched roof to allow natural light to flood into the space below.

Lantern roofs consist of a framework of bars or glazing bars that support multiple glass panels. These panels can be either double-glazed or triple-glazed to provide insulation and energy efficiency.

These adaptable roofs are well suited for a variety of locations in properties, such as flat-roofed extensions, orangeries, newly constructed structures, and dining areas in kitchens. 

They seamlessly combine innovation with practicality, creating a harmonious fusion of form and function.

What is the difference between a lantern roof and a skylight?

While both lantern roofs and skylights serve the purpose of bringing natural light into a space, there are key differences between the two:

Lantern Roof

A lantern roof is a more elaborate structure that typically sits above a roof and has a multi-pane design with vertical or sloping sides. It often serves as an architectural feature and can be a central design element in a room.


A skylight is a simpler, single-pane window installed directly into the roof. Skylights are more function than feature, and are primarily designed to provide light and ventilation.

 Are lantern roofs a good idea?

Lantern roofs can be an excellent addition to your home for several reasons:

1. Enhanced Natural Light

Lantern roofs allow an abundance of natural light to enter a space, reducing the need for artificial lighting during the day.

2. Visual Appeal

They can enhance the aesthetics of your home and create a stunning focal point in any room.

3. Increased Property Value

Well-designed lantern roofs can add value to your property.

4. Improved Ventilation

Some lantern roofs can be opened to allow for natural ventilation, making your space more comfortable.

Is there anything I need to consider before getting a lantern roof?

Before installing a lantern roof, consider the following:

– Planning Permission: Check local building regulations and planning permission requirements.

– Budget: Lantern roofs can vary widely in price, so establish a budget early on.

– Maintenance: Glass and framework require regular cleaning and maintenance to ensure longevity. However, options such as self-cleaning glass can greatly reduce the maintenance required.

– Style and Design: Consider the architectural style of your home and choose a lantern roof that complements it.

Do lantern roofs make the room cold?

Modern lantern roofs are designed with energy efficiency in mind. Properly installed and insulated lantern roofs should not significantly affect the room’s temperature. 

However, selecting high-quality glazing and insulation is crucial for maintaining comfort and energy efficiency.

Are lantern roofs noisy in the rain?

Rain noise can be a concern with some roof lanterns, but modern designs often include noise-reduction features. 

Double glazing, as well as soundproofing materials, can help minimise noise from rain or other external sources.

Do lantern roofs get condensation?

Condensation can occur on any glazed surface, including lantern roofs, when there is a significant temperature difference between the inside and outside. 

Proper ventilation and insulation can help reduce the likelihood of condensation.

Can you put a lantern roof on an existing conservatory?

Yes, it is possible to retrofit a lantern roof onto an existing conservatory to enhance natural light and aesthetic appeal. 

However, it’s essential to consult with a professional to ensure that your existing structure can support the additional weight and design considerations.

Are lantern roofs prone to leaking?

The risk of leaks largely depends on the quality of installation and the materials used. 

To minimise the risk of leaks, it’s crucial to hire experienced professionals and choose high-quality lantern roof systems that are specifically designed to be weather-resistant.
