In modern architectural design, natural light is more than a practical necessity—it’s a defining feature. Whether you’re designing a luxury extension, upgrading a kitchen, or remodeling a commercial space, the integration of daylight has become an essential part of aesthetics and well-being. One of the most elegant and effective ways to achieve this is by installing lantern roof lights.
Blending traditional charm with contemporary engineering, lantern roof lights provide expansive overhead illumination, increase spatial perception, and add architectural grandeur. In this comprehensive guide, we’ll explore the benefits, types, materials, applications, installation tips, maintenance, and emerging trends related to lantern roof lights. Whether you’re a homeowner, architect, or contractor, this resource will help you make an informed decision.
What Are Lantern Roof Lights?
Lantern roof lights are glazed structures, often rectangular or square, that sit atop a flat or low-pitched roof. They resemble miniature glass conservatories and are designed to project above the roofline, capturing and distributing natural light from multiple angles.
Unlike flat rooflights or traditional skylights, lantern roof lights are built with a raised frame and sloped glazing panels. This geometry not only increases the amount of daylight entering a room but also enhances its sense of space and height.
Key Benefits of Lantern Roof Lights
1. Maximize Natural Light
Thanks to their multi-angled design, lantern roof lights capture daylight from all directions. This results in more consistent and balanced light distribution, reducing reliance on artificial lighting during the day.
2. Create a Focal Point
Architecturally, lanterns add visual interest and sophistication. Whether installed in a kitchen extension or a commercial atrium, their striking design becomes a centerpiece of the room.
3. Enhance Spatial Perception
The raised structure and glazed panels give an illusion of higher ceilings, making interiors feel more open and airy. This is particularly effective in single-story extensions and smaller rooms.
4. Improve Ventilation (Optional)
Many lantern roof lights come with opening vents, which can be manual or electric. These help regulate indoor temperature and improve air circulation, especially in kitchens and conservatories.
5. Energy Efficiency
High-performance glazing and thermal break frames help maintain indoor comfort. With proper design, lanterns can reduce heating and lighting bills while still meeting energy codes.
Types of Lantern Roof Lights
There are several styles to choose from depending on the size, shape, and function of your space.
1. Traditional Pyramid Lanterns
A classic four-sided design that suits symmetrical or square roof spaces. Often used in heritage-style homes or where a strong central feature is desired.
2. Rectangular Lanterns
Ideal for modern homes and large extensions, these have a longer profile and often include a ridge beam running along the center for structural support.
3. Contemporary Frameless Lanterns
These are minimal in appearance, with slim or concealed frames, giving a clean, edge-to-edge glass look. They’re perfect for high-end residential and commercial projects.
4. Ventilated Lanterns
Incorporate opening roof vents (either manual or electric) to allow natural air movement. Great for spaces that generate heat or humidity.
Materials and Glazing Options
Frame Materials
- Aluminium: Most common for its durability, low maintenance, and ability to support large glass panes with minimal framing.
- uPVC: Budget-friendly and thermally efficient but often bulkier and less sleek.
- Timber: Offers a traditional aesthetic but requires regular maintenance and is typically more expensive.
Glazing Types
- Double Glazing: Standard for energy efficiency and sound insulation.
- Triple Glazing: Ideal for colder climates or energy-conscious builds.
- Toughened Safety Glass: Required for overhead applications to ensure durability.
- Low-E Glass: Minimizes heat loss and blocks UV rays.
- Self-Cleaning Glass: Uses a special coating to break down dirt and reduce maintenance.
Where Are Lantern Roof Lights Used?
1. Residential Extensions
In kitchen-diners, living rooms, and open-plan spaces, lanterns bring the “wow” factor. They elevate single-story additions from functional to fabulous.
2. New Build Homes
Modern homes often include flat roof sections. A lantern roof light transforms these into light-filled focal points.
3. Commercial Buildings
Used in lobbies, retail spaces, or boardrooms, they help reduce lighting costs while improving ambiance and brand perception.
4. Conservatories and Orangeries
Historically rooted in conservatory design, lanterns give a timeless elegance to garden rooms and transitional indoor-outdoor spaces.

Design Considerations
Before choosing your lantern roof light, it’s important to consider the following:
- Orientation: North-facing lanterns provide consistent but cooler light. South-facing installations may require solar control glass to reduce glare and heat gain.
- Size: Larger lanterns increase light penetration but may require additional structural support. Always work within the span limitations of your roof system.
- Pitch: Steeper angles improve drainage and light angles but may increase visual bulk. Typical pitches range from 15° to 30°.
- Security: High-quality lanterns include secure glazing, locking mechanisms for openers, and tamper-proof fixings.
Installation Guidelines
- Structural Preparation: The roof deck must be reinforced to accommodate the lantern’s weight and shape. This usually involves constructing a timber or steel upstand to house the frame.
- Waterproofing: Ensure proper flashing and waterproof membranes are applied around the perimeter to prevent leaks.
- Safety Compliance: All components should comply with building regulations, including thermal performance (U-values), fire safety, and structural load requirements.
- Professional Fitting: Due to their complexity, lantern roof lights should be installed by experienced professionals to ensure airtightness, drainage, and insulation.
Maintenance Tips
- Clean the glass regularly with non-abrasive materials. Self-cleaning coatings reduce frequency.
- Inspect seals and joints annually for signs of wear.
- Test opening mechanisms, especially for electric vents, to ensure smooth operation.
- Clear drainage channels around the base of the lantern to prevent water pooling.
Trends in Lantern Roof Lighting
Minimalist Design
Frameless and ultra-slim profiles offer a seamless view of the sky and complement minimalist interiors.
Smart Ventilation
Lanterns with sensors that open or close vents based on temperature or rain detection are becoming more popular in smart homes.
Biophilic Integration
Combining natural light with indoor plants and natural materials aligns with the biophilic design trend, promoting health and wellness.
Sustainable Materials
Manufacturers are leaning into recycled aluminum, sustainable timber, and energy-efficient glass to support green building goals.
Choosing the Right Supplier
Quality varies widely in the market, so it’s crucial to choose a supplier known for:
- Thermal performance: Look for certified U-values.
- Weather resistance: Ask about wind and snow load ratings.
- Warranty: Reputable manufacturers offer at least a 10-year guarantee.
- Customization: The ability to specify size, color, glazing, and ventilation features.
