SKYLIGHT WINDOWS | An Architect Explains
Skylight window (also called a roof window) is a window installed in the ceiling. It may be fixed or open-able for ventilation. Skylight adds beauty to a house and allows natural light to stream into a room from overhead. If you have an attic or a dark closet or room, you can get sunlight into it via a skylight that runs along the roof.

WHAT ARE THE DISADVANTAGES OF A SKYLIGHT WINDOW?
Climate Control: During hot summer months, solar heat gain through the skylight may compel you to readjust the air conditioner’s thermostat to compensate raising power bills. During winter, the frigid air, snow and ice on a skylight can likewise force you to use more heating energy. Condensation that forms on the inside of a skylight also can be a problem in winter.
Cleaning: Most skylights do not have coverings or window treatments, so dust can accumulate quickly. Cleaning and dusting high skylights can be a problem. Dusters with extended handles and ladders are necessary. Moreover, you’ll have to climb onto the roof to clean the exterior.
Fading of upholstery: The intense sunlight also can cause fading of exposed furnishings.
