A roof lantern, sometimes called a lantern roof, is a raised glazed structure fitted into a flat or shallow pitched roof. Because the sides are angled rather than flat, it pulls in daylight from every direction across the whole day, and adds a real sense of height to the room below. It is not the same as a flat rooflight, which sits flush with the roofline and is a simpler, lower profile option.
Roof lanterns are most often added above a kitchen extension, dining space or open plan living area, and they are also one of the most effective ways to bring an older flat roofed extension or a tired conservatory back to life. Our lanterns use high quality aluminium frames with a choice of finishes, made to measure in a range of sizes and configurations.
Every lantern is measured, supplied and fitted by our own team from our Garforth base. Before you commit to anything you can visit the showroom on Main Street to see samples and colour swatches in person, and use our large touchscreen design tool to see how the options look.

Slim aluminium sightlines mean more glass and less frame, so you get the maximum amount of daylight from the opening in your roof. Thermally efficient, low maintenance, and available in a choice of finishes to suit a modern extension or a period property.

The most popular reason our customers add a lantern. Daylight from above makes an open plan kitchen diner feel significantly larger, and works particularly well alongside bifold or French doors out to the garden. We can design the lantern in as part of a wider extension or fit one into an existing flat roof.

A roof lantern is raised above the roofline with angled sides, so it draws light in from the sides as well as directly above and adds a feeling of height. A flat rooflight sits flush with the roof, a simpler and lower profile option that suits smaller spaces or a more understated finish. We will talk you through which suits your room at your free design visit.

Answers to the questions we get asked most about roof lanterns.
A roof lantern, or lantern roof, is a raised glazed structure fitted into a flat or shallow pitched roof. The angled sides draw daylight in from every direction across the day and add a real sense of height to the room below. They are most often fitted above kitchen extensions, dining rooms and open plan living spaces.
A roof lantern is raised above the roofline with angled glazed sides, so light comes in from the sides as well as above. A flat rooflight sits flush with the roof and is a simpler, lower profile option. Lanterns give more light and more of a feature, rooflights are more understated and often better suited to smaller spaces.

In most cases yes, roof lanterns are designed specifically for flat and shallow pitched roofs. The roof needs a properly built and weathered upstand for the lantern to sit on. We check your existing roof structure as part of the free design visit and tell you honestly what is possible.
Yes, and it is one of the most popular upgrades we do. Replacing old polycarbonate or glass with a modern insulated roof and a central lantern gives you a room that stays comfortable all year without losing the natural light.
Aluminium lanterns are designed to be low maintenance. A soft brush or squeegee on an extendable pole with warm soapy water is usually all that is needed from inside or from ground level. Some glazing options include a self-cleaning coating that reduces this further, ask us which options are available for your lantern.
Most roof lanterns fall under permitted development rights, particularly as part of a single storey extension, subject to size and position. Listed buildings and conservation areas can have additional restrictions. We check this as part of your free design visit so you know where you stand before committing.
Once the flat roof and upstand are prepared, most lanterns are fitted and weathered within a day. Timescales for the wider job depend on whether the roof needs building or altering first. We give you a clear schedule at your design visit, and the work is carried out by our own team rather than subcontracted.
