Factors To Consider When Buying Rooflights and Skylights

Home Improvement

Rooflights and skylights are often used interchangeably to refer to windows installed on the roof of a building. Both provide natural light and can help to reduce the need for artificial lighting, improve energy efficiency, and enhance the ambiance of a space.

The main difference between roof lights and skylights is the location and design of the window. Rooflights are typically installed flat on the roof and can be any shape or size. On the other hand, skylights are usually installed at an angle and are often dome-shaped or triangular.

Rooflights and skylights can be made of various materials, such as glass, plastic, and acrylic. They can also be fixed or movable and have manual or motorized opening mechanisms. The type of roof light or skylight you select will be determined by your specific needs and requirements, such as the amount of natural light desired, the need for ventilation, and the building’s design.

When buying rooflights or skylights, it is important to consider the following factors:

  • Size and Shape: To determine the size you require, measure the area where you intend to install the rooflight or skylight. Consider how the shape of the rooflight or skylight affects the amount of light it provides and how it affects the aesthetic of your home.
  • Energy Efficiency: Think about the energy efficiency of the rooflight or skylight, especially if you want to save money on your energy bills. To reduce heat loss and gain, look for products with a high thermal rating, double glazing, and low-E coatings.
  • Ventilation: Consider the available ventilation options, as a rooflight or skylight can also provide fresh air. Look for products with manual or electric ventilation options.
  • Glazing: The type of glazing you select can affect how much light, heat, and UV radiation enters your home. Consider your options and choose the glazing that best meets your requirements.
  • Installation: Make sure the rooflight or skylight you choose is suitable for your roof type and that the installation process is not too complicated. Look for products with a straightforward installation process, or consider hiring a professional to install them.
  • Style and Design: Consider the style and design of the rooflight or skylight, as this will impact the overall appearance of your home. Choose a style and design that complements your home’s design and that you find appealing.
  • Budget: Finally, keep your budget in mind when purchasing a rooflight or skylight. High-end products with advanced features and better insulation will cost more, but the investment may be worthwhile in the long run.

Rooflights and skylights can provide numerous benefits to your home, including:

  • Increased natural light: The main advantage of installing rooflights and skylights is that they let in more natural light, making your home feel brighter and more spacious.
  • Rooflights and skylights can reduce the need for artificial lighting by bringing in natural light, which can save energy and lower your energy bills. Energy-efficient models with high-performance glazing and insulation can reduce energy consumption even further.
  • Improved ventilation: Many rooflights and skylights include ventilation options, enhancing your home’s indoor air quality and reducing moisture and condensation buildup.


Roof lights and skylights can provide various benefits, such as improved natural lighting, lower energy costs, and improved interior design. However, it is critical to properly install and maintain roof lights and skylights to avoid leaks and other issues that could jeopardize the roof and building.
