A skylight is sloped at ____ degrees or more vertical.

The correct answer is: 12

A skylight must be sloped at 12 degrees or more to ensure proper water drainage and to minimize the risk of leaks, condensation, and ice buildup. The specified angle also helps to reduce glare and improve the overall efficiency of the skylight by allowing more natural light to enter while preventing water from pooling on the surface. Choosing a slope of 12 degrees promotes a balance between effective drainage and structural stability. A slope less than this could lead to water accumulation, which can compromise the integrity of the skylight and potentially lead to significant maintenance issues. Therefore, 12 degrees is the industry standard for skylight installations to ensure optimal performance and durability.
