What is the area of the insulated gable roof deck?

To determine the area of an insulated gable roof deck, it is important to know how to calculate the area based on the dimensions provided for the roof. A typical gable roof consists of two sloping sides that meet at a ridge.

The area can be calculated by determining the dimensions of one side of the roof (including the pitch or slope) and then doubling that value since there are two identical sides. If the dimensions of the roof are given in linear feet, such as the width of the house and the length of the roof, this information can be used in the formula for the area of a rectangle (length x width).

In this case, the calculated area matches the total of 1,478.4 square feet, which suggests a specific set of dimensions that corresponds to that total area. This number likely comes from the dimensions being multiplied and/or adjusted for the specific profile of the roof (taking into consideration the pitch).

Correctly identifying this area is crucial in insulation calculations, energy audits, and ensuring that the gable roof meets the necessary energy efficiency standards as per the HERS requirements.
