Roof lanterns are architectural features that provide natural light and a sense of openness to interior spaces. They are particularly popular in extensions, orangeries, and areas of the home that benefit from additional daylight. This guide explores the various types of roof lanterns available, their associated costs, and other critical information for prospective buyers.

The average cost to install a roof lantern on an orangery can range from £3,500 to £6,000. This price includes the cost of the roof lantern, which varies based on the material—whether it’s timber, aluminium, or uPVC—as well as the complexity and size of the lantern. Additionally, the installation costs are factored into this range, which can fluctuate depending on the specific requirements of the project

Types of Roof Lanterns

Roof lanterns come in several styles and materials, each offering distinct advantages and aesthetic qualities. Choosing the right type of roof lantern involves considering the architectural style of your home, maintenance requirements, and budget.

Traditional Roof Lanterns:

Traditional roof lanterns are typically made from timber, providing a classic and timeless look. These are ideal for period properties or homes with a more traditional aesthetic. Timber roof lanterns can be highly customizable in terms of design and finish. However, they require regular maintenance to protect against weathering and to maintain their appearance.

Contemporary Roof Lanterns:

Contemporary roof lanterns often feature aluminium frames, which offer a sleek and modern look. Aluminium is known for its strength and durability, making it a low-maintenance option. These lanterns have slim sightlines that maximize the amount of light entering the space, making them perfect for modern homes that prioritize clean lines and open spaces.

uPVC Roof Lanterns:

uPVC roof lanterns are a cost-effective choice that combines good insulation properties with minimal maintenance. They are versatile and can be designed to mimic the appearance of more expensive materials like timber. uPVC is also highly durable and resistant to weathering, making it a practical option for many homeowners.

Cost of Installing Roof Lanterns

Understanding the cost of installing a roof lantern is crucial for budgeting and planning. Costs can vary based on the material, size, and complexity of the installation

Material Costs:

  • Timber: These are typically priced between £2,500 and £5,000. The price can vary depending on the size and design complexity, with larger or more intricate designs costing more.
  • Aluminium: Aluminium options generally cost between £1,800 and £3,000. While the initial cost is higher compared to uPVC, aluminium’s durability and low maintenance needs can justify the investment.
  • uPVC: The most budget-friendly option, uPVC roof lanterns range from £1,000 to £2,500. They offer excellent insulation and are easy to maintain, making them a popular choice for budget-conscious homeowners.

Installation Costs:

Professional installation can add an additional £500 to £1,500 to the total cost. This can vary depending on the complexity of the installation. For example, if structural modifications to the roof are necessary, the costs will be higher. It’s important to get a detailed quote from a qualified installer to avoid unexpected expenses.


Other Considerations

When planning to install a roof lantern, there are several factors to consider beyond just the type and cost.

Energy Efficiency:

Choosing a roof lantern with high energy efficiency can help reduce heating costs and improve the overall comfort of your home. Look for double or triple glazing options to enhance insulation. Low-emissivity (Low-E) glass is also beneficial as it helps reflect heat back into the room, further improving energy efficiency.

Ventilation:

Some roof lanterns come with built-in ventilation options. These can help regulate temperature and improve air quality, which is especially useful in spaces like kitchens and orangeries where heat and humidity levels can fluctuate.

Aesthetics and Design:

The design of the roof lantern should complement the overall style of your home. Customizable options are available to match specific architectural designs and personal preferences. Consider factors such as frame colour, glazing type, and overall shape to ensure the roof lantern enhances your home’s aesthetic appeal.

Planning Permission:

In most cases, roof lanterns fall under permitted development rights, meaning you won’t need planning permission. However, it’s essential to check local regulations, especially if you live in a conservation area or a listed building. Consulting with your local planning authority can help you understand any specific requirements or restrictions.
