What is the height of the ridge from the attic floor if built with a gable roof?

In determining the height of the ridge from the attic floor in a gable roof configuration, several factors come into play, including the design and slope of the roof, as well as standard construction practices. Typically, the height of the ridge is measured from the attic floor to the apex of the roof. A properly designed gable roof often has a ridge height that allows for optimal attic space while meeting building codes and aesthetic preferences.

The choice of 9.3 feet for the ridge height reflects a common standard found in many residential buildings, providing ample headroom in the attic while still facilitating effective drainage and ventilation of the roof system. A ridge height around this dimension generally allows for sufficient space for insulation and HVAC installations, which is critical in energy-efficient designs.

On the contrary, a ridge height significantly lower than this, such as in the other choices, might not provide adequate attic space or could create challenges in terms of ventilation and insulation, which are key components in energy efficiency. Thus, 9.3 feet represents a balance between structural integrity, functionality, and energy efficiency within a residential building with a gable roof.
