Skylight Installation Cost

How Much Does Skylight Installation Cost?

Skylight Installation Cost – Skylights are special kings of windows that are built into the roofs of houses in order to allow natural sunlight to flow in. They are available in a wide variety of styles, energy efficiency ratings and shapes. They can either be installed as a type of passive heating strategy, or for aesthetic purposes.

Types of Skylights

There are three main types of skylights which are explained below:

  • Fixed Skylights – Fixed skylights don’t open. They are the most common choice of skylights and are good for providing stairwells or rooms like attics with an extra amount of light.
  • Tubular Skylights – These skylights are also referred to as sun pipes or light pipes and are composed of roof mounted domes which gather sunlight and sends it to circular openings in the ceiling, normally of 10 or 14 inches in diameter, by way of a reflective tube.They are usually installed in hallways, closets, and small sized rooms as these skylights are small and circular shaped.
  • Ventilating Skylights – These skylights can be opened, providing any room not only with natural sunlight, but also with fresh air. They are mostly installed in bathrooms and kitchens as they reduce moisture and improve the flow of air. These skylights can be opened as well as closed either manually, via automatic sensor, a motorized hand crank, or a remote control.


  • When considering a new purchase, the size of a skylight should not exceed 5% of the entire floor area of a room with many windows.
  • It should also not go over 15% of the entire area of the floor for rooms that do not have a lot of windows.
  • The best time for west facing skylights to capture heat and sunlight is afternoon.
  • East facing skylights are best for maximizing the effect of the morning heat and sunrays.
  • Skylights that are south facing can be too hot for summers and are the best option for capturing sunrays in winter.
  • Skylights that are north facing do not provide much heat, and are good for the provision of consistent light.
  • As recommended by professionals, skylight slopes should be the same as the latitude of your residence and an additional 5 to 15 degrees.
