The primary purpose of a skylight in roofing is to allow natural light into a building. Skylights are designed to be installed in roofing systems to enhance the interior environment by harnessing daylight, which can reduce the need for artificial lighting during the day. This not only contributes to energy savings but also improves the overall ambiance of a space by making it feel larger and more open. By strategically placing skylights, builders and architects can create a brighter, more welcoming atmosphere, which can enhance the aesthetics of a room and contribute positively to the occupants' well-being.

In contrast, insulation is a separate element of roofing designed to regulate temperature and energy efficiency, not the primary function of a skylight. While drainage systems are important for managing water flow and preventing leaks, skylights do not inherently serve this role. Additionally, while some elements of the roof contribute to its structural integrity, skylights themselves do not provide support for the roof structure; instead, they are openings that allow light in.
