A Roof Lantern or a Skylight – Which is Best for Your Home?

Natural light can transform a home, making it feel more open, vibrant, and welcoming. When considering ways to bring more sunlight into your living space, roof lanterns and skylights are great options. Both have their benefits and can significantly enhance your home’s aesthetic and functionality. But which is the best choice for you? 

What is a Roof Lantern?

A roof lantern is a type of architectural feature installed on the roof of a building. It’s a glass structure, often dome-shaped, that allows natural light to flood into the space below. 

In modern homes, roof lanterns are typically used in extensions or rooms with flat roofs. They provide an elegant and sophisticated look, adding a touch of luxury to any space. Besides aesthetics, roof lanterns are excellent for brightening up large areas and creating a sense of openness.

What is a Skylight?

Skylights, on the other hand, are flat or domed windows installed directly into the roofline. They come in various shapes and sizes, including fixed, vented, and tubular skylights. 

Modern skylights are popular for their ability to provide direct sunlight into specific areas, such as attics, bathrooms, and hallways. They are versatile and can be installed in pitched or flat roofs, making them a flexible option for many homeowners.

Cost Comparison

When considering the cost, roof lanterns and skylights vary significantly. Roof lanterns tend to be more expensive due to their complex design and installation process. The average cost for a roof lantern can range from £800 to £1900 or more, depending on the size, installation costs and materials used.

Skylights are generally more affordable, with average costs ranging from £500 to £800. The price varies based on the type of skylight, its size, and the complexity of the installation. It’s also important to consider long-term costs, such as energy efficiency and maintenance, which can impact your overall budget.

Planning Permission Requirements

Whether you need planning permission for a roof lantern or a skylight depends on several factors, including the size of the installation and local building regulations. In many cases, roof lanterns require planning permission, especially if they protrude significantly from the roofline or are installed in a conservation area.

Skylights typically have fewer planning restrictions, but it’s always best to check with your local planning authority to ensure compliance. Generally, if the skylight doesn’t alter the building’s appearance dramatically, planning permission might not be necessary.

Structural Considerations

Installing a roof lantern or a skylight involves structural considerations to ensure the stability and safety of your home. Roof lanterns require a solid framework to support their weight and must be carefully integrated into the existing roof structure. This often means reinforcing the roof and ensuring proper waterproofing to prevent leaks.

Skylights, while lighter, still require precise installation to avoid compromising the roof’s integrity. Proper sealing and insulation are crucial to prevent leaks and ensure energy efficiency. Consulting with a structural engineer or a professional installer is recommended for both options.

Installation Process

The installation process for roof lanterns and skylights varies in complexity and duration. Installing a roof lantern involves several steps, including creating an opening in the roof, constructing a supportive frame, and carefully fitting the glass panels. This process can take several days to complete, depending on the size and complexity of the lantern.

Skylights are generally quicker to install. The process involves cutting an opening in the roof, fitting the skylight into place, and ensuring it’s properly sealed and insulated. Most skylight installations can be completed within a day or two.

Energy Efficiency

Energy efficiency is a critical factor to consider when choosing between a roof lantern and a skylight. Roof lanterns, with their larger glass surfaces, can potentially lead to greater heat loss or gain, depending on the season. However, modern roof lanterns are designed with energy-efficient glazing to minimise this impact.

Skylights are known for their energy-efficient designs, especially when fitted with double or triple glazing. They can help reduce heating and cooling costs by providing natural light and reducing the need for artificial lighting during the day. Additionally, vented skylights can improve ventilation, contributing to a more energy-efficient home.

Aesthetic Appeal

Both roof lanterns and skylights offer unique aesthetic benefits. Roof lanterns add a dramatic focal point to any room, creating a sense of grandeur and elegance. They are particularly popular in kitchens, dining rooms, and living areas, where they can highlight architectural features and provide ample natural light.

Skylights, while more subtle, can also enhance the beauty of a space. They are ideal for areas where you want to maximise light without making a bold statement. Skylights are versatile and can be used in various settings, from contemporary to traditional homes, complementing different architectural styles.

Natural Light and Ventilation

One of the primary reasons homeowners choose roof lanterns or skylights is to increase natural light. Roof lanterns are excellent for illuminating large spaces, creating a bright and airy atmosphere. The natural light they provide can enhance the mood and well-being of occupants, making the space feel more inviting.

Skylights are also great for bringing in natural light, particularly in areas that might otherwise be dark or confined. Vented skylights offer the added benefit of improved ventilation, allowing fresh air to circulate and helping to maintain a comfortable indoor environment.

Maintenance and Durability

Maintenance is an important consideration for both roof lanterns and skylights. Roof lanterns require regular cleaning to keep the glass clear and free from debris. They also need periodic inspections to ensure the seals and framework remain intact.

Skylights, while generally low-maintenance, still require occasional cleaning and inspection. The seals and flashing should be checked regularly to prevent leaks and ensure the skylight remains energy-efficient. Both roof lanterns and skylights are designed to be durable, with high-quality materials that can withstand the elements.

Choosing between a roof lantern and a skylight ultimately depends on your budget and aesthetic preferences. If you’re looking for a dramatic and elegant feature that can illuminate a large area, a roof lantern might be the best choice. However, if you prefer a more subtle and versatile option that can be installed in various spaces, a skylight could be ideal.
