If you have a room that feels dark, a roof lantern might be the answer. They bring daylight in from above, which can change how a space feels from the moment you walk in.
What is a roof lantern?
A roof lantern is a glazed structure that sits on top of a flat roof, rising above it to let natural light into the room below. They’re often seen on extensions, kitchens, orangeries and garden rooms, and come in a range of shapes and styles, from traditional to contemporary.
Where do roof lanterns work best?
- Kitchen extensions. Daylight over a kitchen island or dining table can make the whole space feel brighter and more open.
- Single-storey rear extensions. If your extension is deep, a lantern helps light reach the middle of the room, not just the area near the doors.
- Dining and living areas. A lantern above a seating or dining area gives a feeling of height and openness.
- Orangeries and garden rooms. Lanterns suit these spaces, linking the room with the sky and the garden.
- Dark central rooms. Where side windows aren’t an option, light from above can make a big difference.
Things to think about before you choose
Heat and light. A lot of glass means a lot of daylight, but it’s worth thinking about summer heat and winter warmth. The glass specification, shading and ventilation all play a part, so ask about your options.
Size and proportion. A lantern should suit the size of your roof and room. Too small and it won’t make the impact you want, too large and it can overpower the space.
Style. Choose a design that suits your home. A traditional lantern can sit well on a period property, while cleaner, slimmer lines work well on modern extensions.
Your existing roof. Whether a lantern can be added to an existing flat roof depends on its structure, so a proper survey matters.
Planning and building regulations. Whether you need permission depends on your property and plans, and building regulations may apply. We can talk this through with you, and it’s worth checking with your local planning authority too.
Why get a roof lantern fitted properly?
A roof lantern is only as good as its installation. Careful measuring, good weatherproofing and attention to detail at the join between the lantern and the roof all matter. That’s why we handle everything from consultation and design through to installation and aftercare.
