Imagine- lounging on your sofa after a long day with a beam of light radiating down on you. No worries, just sunbathing lizard time! Skylights and roof windows are two of those home additions that appeal to almost anyone. They bring in natural light, help improve mood, and look just plain cool. But did you know there's a difference between skylights and roof windows? Heck, you may not have even known that roof windows were their own separate entity. 

Being in the roofing industry for nearly thirty years, RoofCrafters knows a thing or two about these nifty little glass gadgets. Just like eyebrows, they aren't twins, but sisters. Their similarities are significant enough that they're often mistaken for being the same, while their differences set them apart from one another. If you've never put the pieces together regarding these two, you're in for a treat!

This article breaks down the common differences between skylights and roof windows, so you know what you're in for if you decide to have one installed. By the time you finish reading, you'll know what they are, how they function, and which types of homes each are suited for. That's a lot to cover, so let's jump right in!

Skylights & Roof Windows: What Sets Them Apart? 

 

Let's shed some light on their unique characteristics.

 

Skylights

  • Position: Skylights are typically installed on the roof, directly overhead.

  • Functionality: Designed to bring additional natural light into a space, skylights often cannot be opened or provide ventilation.

  • Placement: Skylights are commonly used in areas with limited access to external walls, such as bathrooms or hallways.

  • Variety: Available in various shapes and sizes, including fixed, vented, tubular, and custom designs.

  • Installation: Skylights are integrated into the roof structure and may require professional installation.

Roof Windows

  • Position: Roof windows are installed within the slope of the roof, providing a view as well as light.

  • Functionality: Roof windows are designed to open, offering ventilation and the option for natural airflow.

  • Placement: Often placed in attics or loft spaces, roof windows serve as both light sources and points of view.

  • Variety: Roof windows come in different styles, including top-hung, center-pivot, and balcony roof windows.

  • Installation: Roof windows are typically integrated during the construction or renovation phase, requiring precise placement.

Shared Aspects

  • Natural Light: Both skylights and roof windows contribute to increased daylight within a living space.

  • Aesthetics: Both options enhance the aesthetics of a room, providing a connection to the outdoors.

  • Energy Efficiency: Well-designed skylights and roof windows can contribute to energy efficiency by reducing the need for artificial lighting.

In essence, while skylights and roof windows share the primary goal of introducing natural light, their distinct features cater to different preferences, spaces, and functionalities. Whether you're envisioning a starlit view from your bedroom or seeking additional illumination in a central hallway, understanding these differences will guide you toward the perfect choice for your home!

Understanding Which Option is Right for Your Home

 

How do you know what to pick? Let's break it down:

Skylights

 

Skylights are versatile additions that can enhance a variety of roof and home types, offering both functional and aesthetic benefits. Here's a breakdown of the scenarios where skylights are best suited:

         Pitched Roofs:


    • Skylights are particularly well-suited for pitched or sloped roofs. Their installation aligns seamlessly with the roof's angle, allowing for optimal natural light penetration. Pitched roofs often provide an ideal surface for skylights to capture sunlight effectively.

    Modern and Contemporary Homes:

    • Homes with modern or contemporary architectural styles often embrace the use of skylights. The clean lines and open spaces characteristic of these designs are complemented by skylights, creating a sense of openness and connection with the outdoors.

          Limited Exterior Wall Space:


    • In homes where exterior wall space is limited, such as townhouses or structures surrounded closely by neighboring buildings, skylights become essential for introducing natural light. They maximize daylight without relying solely on traditional windows.

    Private Spaces:

    • Skylights work well in areas where privacy is crucial, such as bedrooms and bathrooms. Placed strategically, they allow for ample natural light without compromising privacy, as they are often positioned high on the roof.

    Energy-Efficient Homes:

    • Homes with a focus on energy efficiency can benefit from skylights. Well-designed skylights harness natural light, reducing the need for artificial lighting during the day and potentially lowering energy consumption.

 

Roof Windows

 

Roof windows, with their unique characteristics, perform best in specific roof and home types:

        Attics and Loft Spaces:


    • Roof windows are particularly well-suited for attics and loft spaces that have been converted into habitable areas. They provide an excellent solution for bringing natural light into these spaces, transforming them into functional living areas.

          Ventilation Requirements:


    • Homes requiring enhanced ventilation often benefit from roof windows. Many roof window designs are operable, allowing for the release of warm air during the summer, contributing to improved airflow and comfort.

    Flat Roofs:

    • While skylights are often associated with pitched roofs, roof windows can be suitable for flat or low-pitched roofs. They can be installed with a slight pitch to allow water runoff and still provide effective daylighting.

    Aesthetic Appeal:

    • Roof windows add a touch of charm and aesthetic appeal to various home types. They bring character to spaces while serving a practical purpose, making them suitable for homes where aesthetics play a significant role in design considerations.

    Customization Options:

    • Homeowners seeking diverse styles and configurations can find roof windows that suit their preferences. Options like top-hung, center-pivot, and balcony roof windows offer customization for different architectural needs!

Skylights and roof windows each have their ideal specifications. Skylights excel in pitched roofs and modern designs, while roof windows are well-suited for attic conversions, homes with ventilation needs, and those seeking unique aesthetic elements. The choice between skylights and roof windows depends on the specific characteristics and design goals of the home.
