One issue relating to the installation of skylights is adequate ventilation; it is essential that this issue be properly addressed. There should be a proper ventilation system upon installation of a skylight that is energy-efficient and functional. It should be correctly designed and installed in order to maintain a continuous airflow in the area between and around the roof opening. It is important that it be well-ventilated and that the pathway from the intake vents to the exhaust outlets not be obstructed.


Skylights are extremely important when designing a roofing structure. Basically, these windows to the world allow the warmth and brightness of the daylight to come from the outside to the interior of the building, helping to invigorate the space; however, these openings also have the potential to generate drafts and create an uncomfortable environment. This type of system generally loses approximately forty-five percent more heat during the winter season because warm air rises. Once the warm air has reached the ceiling, it encounters the cold surface of the skylights, which cools the heated air and creates a draft that will gradually reduce the comfort level of the space under the skylight. The most effective method to combat this problem is to have an adequate ventilation system in the building.


There are several techniques to eliminate many of the problems associated with the building and maintenance of a continuous air passage for a roofing structure. Regardless of how long a winter season may last, one thing that often occurs to a roof is the formation of icicles along its edges as well as the build-up of ice dams on the roof and skylight frames, ultimately causing water to back-up and penetrate the roof and the exterior walls.

To avoid this, a notch can be cut at the corners of the rafters on both the upper and lower sides of the skylights. This allows air to flow freely from the intake vents to the exhaust outlets. During the winter, if ice formation is a problem, interior storm panels can be installed to reduce heat loss and eliminate drafts.

Extremely high ceilings also require similar continuous and uninterrupted ventilation. There should be air barriers and equal soffit and ridge outlets to provide a continuous air flow from the lower portion to the peak of the roofing structure.

Infiltration and Condensation

Skylights are not just a good source of natural light, necessary ventilation, or dramatic views; unfortunately, they are also an undesirable source of condensation and outside air infiltration. When such a system is installed, it is imperative to first consider such issues. A well-built skylight will be resistant to condensation; however, without proper installation it can end up being a nuisance. Improper installation can allow air to infiltrate through the space between the frame and the glazing. To keep these negative things from happening, proper care must be taken during the installation process.

Skylights are an innovative way to naturally illuminate and refresh a commercial building. They may alleviate depression, promote work efficiency, save energy, and create a healthy environment. Although it could be a wonderful addition, it could also end up being a source of many problems. Without proper installation, a skylight could impede the continuous flow of air within the roofing structure, cause condensation problems, and be a source of outside air infiltration.

To avoid these issues, care should be taken in choosing a high quality system. It should be properly installed and well-ventilated, and the air path should not be blocked. With proper ventilation, this new window to the outside world can be a source of enjoyment to those who occupy the building for many years to come!
