Experience the freedom of obtaining the products you desire, tailored to your preferences. Our dedicated team is always available to assist you whenever you require assistance. Your satisfaction is our priority.

Structural Integrity

Our lantern roofs are BBA-approved and come with a 25-year life expectancy certificate. They have been wind-tested at speeds of up to 130mph and fire-tested by Warringtonfire.


Our lantern roofs have been tested by Exova Warringtonfire to ensure compliance with fire safety. Our conservatory roofs also fully comply with the latest Building Regulations and have been pre-approved by Assent and JHAI.

Energy Efficient

Our decorative super-insulated columns provide high levels of comfort and have a U-value of only 0.15 W/m²K. Our slimline ridges are 30% slimmer than traditional ridges and come with high-performance thermal breaks to prevent cold spots and condensation.

Internal Pelmet

Our lantern roofs consist of a vaulted ceiling and have an internal pelmet around the perimeter. This provides a space for you to install lights or speakers in a living space that is usually difficult to light.

Versatile Design

It is a common misconception that lantern roofs only suit period properties. While it is true that lantern roofs have a classic style, they can be customised in numerous different ways to meet the stylistic requirements of any modern property as well.

Because our lantern roofs are quality-checked and manufactured to meet incredibly high standards, you can have peace of mind knowing that your new lantern roof will keep you and your living space protected from any adverse weather conditions throughout the year.

Because of the fewer bars used and the extended eaves beams rather than a flat roof, our lantern roofs will be able to flood any living space with light. Additionally, the internal pelmets and external cornices make for beautiful orangery roofs.

A decorative cornice is used outside to hide the guttering and create beautiful sightlines. The internal insulated pelmet will enable you to enjoy better lighting and thermal performance. You can even opt for integrated spotlights and speakers to enhance your experience. Whatever you’re looking to achieve, speak to our team about your vision today.

Frequently Asked Questions

What is a lantern roof?

A lantern roof is rectangular and consists of central glass panes that are pitched to mimic the appearance of a roof. A lantern roof can be added to a conservatory or even an existing room that has a flat roof.

Do roof lanterns lose heat?

Because of our thermally efficient glass, our lantern roof will not lose heat. Instead, our lantern roof will create a comfortable environment for your Exeter or Devon property, even during the winter. We also offer internally insulated pelmets that will further increase the thermal efficiency of your lantern roof living space.

Do lantern roofs let in more light?

Yes, they do. Lantern roofs can let in three times more light than a standard window, depending on the size of your installation. Despite this, you will not have to worry about harmful UV rays or the glare from the sun because of our various glazing options to cater towards each need.

How do I clean my lantern roof?

To make cleaning your roof as easy as possible, use a handle with a sponge attached to the end and cover your lantern roof with warm, soapy water. We also offer self-cleaning glass if you would like to avoid cleaning altogether.

How much are lantern roofs?

It is difficult to provide a price for your lantern roof as customisation options, your exact location in Exeter, Devon, or the surrounding area, and other factors contribute to the overall cost of your lantern roof. The best way to get a price is to call us at 01392 547272.
