Roof Windows vs. Skylights: What’s the Difference?

When introducing natural light into your home, roof windows and skylights are excellent options. However, while these terms are often used interchangeably, they refer to distinct features with different functionalities. Choosing the right solution for your property depends on your specific needs, style preferences, and the structural considerations of your roof.

This article will explore the key differences between roof windows and skylights, helping you make an informed decision. Whether you’re considering hiring a skylight installer or researching the benefits of roof windows, this guide will clarify your options.

What Is a Skylight?

A skylight is a fixed window installed directly into your roof. Its primary purpose is to allow natural light to flood into space, creating a bright and airy atmosphere. Skylights are ideal for rooms that lack sufficient windows or spaces where traditional wall windows are not feasible, such as attics, bathrooms, or hallways.

Skylights come in various shapes and sizes, including flat, domed, and tubular designs. They are generally fixed in place, meaning they don’t open or provide ventilation. However, modern skylight designs may include venting options for added functionality.

Benefits of Skylights:

  • Floods your space with natural light.
  • Enhances the aesthetic appeal of your interior.
  • It can reduce energy consumption by minimising the need for artificial lighting.
  • Suitable for small spaces where roof windows may not fit.

What Are Roof Windows?

Roof windows, on the other hand, are larger and more versatile than skylights. They are designed to be fully functional, offering both natural light and ventilation. Roof windows are typically installed at eye level or within reach, allowing homeowners to open, close, and even clean them with ease.

Unlike skylights, roof windows are often equipped with advanced features such as blinds, UV protection, and double or triple glazing to improve insulation and energy efficiency. They are a popular choice for loft conversions or upstairs rooms with sloped ceilings.

Benefits of Roof Windows:

  • Allows natural light and fresh air to enter.
  • Provides easy access for cleaning and maintenance.
  • Enhances insulation, reducing heating and cooling costs.
  • Adds a modern, functional feature to living spaces.

Key Differences Between Skylights and Roof Windows

Now that we’ve defined both terms, let’s dive into their major differences:

  1. Sky Visibility: Roof windows provide a direct view of the sky. Skylights do not offer a direct view, as they include a diffuser that allows light to enter but does not provide an external view.
  2. Installation and Structure: Installing a roof window requires building a gyprock shaft, which involves more structural work. Skylights are easier to install because they only require a flexi shaft, a diffuser, and an architrave, which are placed directly on the ceiling.
  1. Main Components: Both roof windows and skylights require a base (flashing tray) and a top glass panel. Roof windows always use double glazed glass. Skylights can have either double glazed or acrylic glass, with finish options such as white trans, tinted, or clear.
  1. Customization and Sizes: Roof windows come in standard sizes and can be installed in portrait or landscape orientation, but they cannot be customized. Skylights, on the other hand, can be made in custom sizes to fit specific needs. They can also be installed with a gyprock shaft instead of the full kit, making them look more like roof windows.
  1. Opening and Ventilation Options: Roof windows can be fixed (non-openable) or openable, with manual or electric operation. The electric models also include rain sensors. All roof windows come with fly screens. Skylights can have ventilation slots if required, but they cannot be opened or closed.
  1. Recommended Use: Skylights are ideal for areas where natural light is needed without an external view, such as hallways or bathrooms. Roof windows are commonly used in spaces where aesthetics and design are important, such as living rooms, designer kitchens, or attic bedrooms.
  1. Accessories and Light Control: Roof windows allow for the installation of blinds, either at the time of installation or in the future, making them ideal for bedrooms where light control is needed. Skylights do not have the option to add blinds or block light in any way.

The choice between roof windows and skylights depends on the specific needs of the space. If the goal is to bring in natural light without an external view and with an easy installation process, skylights are the best option. If a functional window with a clear sky view, opening capability, and light control is needed, roof windows are the ideal choice.

Choosing the Right Option for Your Home

Your decision between roof windows and skylights will largely depend on your needs, preferences, and budget. Here are a few scenarios to consider:

  • If you want to brighten a small, enclosed space: A skylight may be the ideal solution for adding natural light to areas like hallways, bathrooms, or storage rooms.
  • If you need both light and ventilation: Roof windows are perfect for bedrooms, kitchens, or converted lofts where airflow is crucial.
  • For a sleek, minimal design: Skylights blend seamlessly into your roof, making them a great option for homeowners who prefer understated aesthetics.
  • For added functionality and access: Roof windows offer better versatility with operability and ease of cleaning.

Installation Considerations

Whether you choose skylights or roof windows, proper installation is key to maximising their benefits. Poorly installed roof windows or skylights can lead to issues such as leaks, poor insulation, or structural damage. Always hire a trusted skylight installer or window specialist to ensure the project meets safety and building standards.

Important Installation Tips:

  • Ensure your roof structure can support the chosen feature.
  • Use high-quality materials to improve energy efficiency and durability.
  • Regularly inspect and maintain your skylight or roof window to prevent wear and tear.

Final Thoughts

While skylights and roof windows serve similar purposes, their differences in functionality, size, and design make them suitable for different applications. Skylights are ideal for adding natural light to small spaces, while roof windows provide a versatile solution with added ventilation and accessibility.

For homeowners in Canberra and beyond, hiring an experienced skylight installer ensures your new feature enhances your property’s aesthetic and energy efficiency. Whether you opt for a sleek skylight or a practical roof window, both options can significantly elevate the comfort and value of your home.
