What is a Gable Roof Area?

The gable roof area is the surface area of a gable roof, which is a type of roof with two sloping sides that come together at a ridge, creating end walls with a triangular extension, called a gable, at the top. This area is important for calculating the amount of roofing material needed.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ \text{GRA} = \frac{30 \times 15}{2} = 225 \text{ ft²} \]

The Gable Roof Area is 225 ft².

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ \text{GRA} = \frac{40 \times 20}{2} = 400 \text{ ft²} \]

The Gable Roof Area is 400 ft².
