When calculating hip roofs, what is the order of operations for estimating areas?

In estimating areas for hip roofs, the correct order of operations is to calculate the main body first and then the extensions second. This approach ensures that you account for the primary structural components of the roof before considering any additional features or extensions, which may complicate the area calculations.

Starting with the main body allows you to establish a baseline area that accurately reflects the majority of the roof's dimensions and design. Once that is calculated, adding the extensions provides a clearer picture of the overall area without the risk of overlapping or confusing calculations. The systematic approach minimizes the risk of errors, which is particularly important in roofing estimates where accuracy is essential for both materials cost and structural integrity.

This method also aligns with common practices in construction estimating, where one typically measures the largest areas first to establish foundation figures before moving on to more detailed or complicated sections.
