How to Calculate Hip Roof Area (USA Method)

Calculating the surface area of a hip roof is different from a gable roof because all sides slope downwards towards the walls. For US homeowners and contractors, accuracy is crucial to avoid material shortages.

Expert Tip: Always measure the building’s footprint (Length x Width) first. Then, calculate the actual slope area using the pitch multiplier. Our tool automatically adds the eave overhangs, which many simple calculators forget.

Why Use This Calculator?

This Hip Roof Area Calculator Pro (USA) uses standard imperial units (Feet and Inches). It converts your measurements into decimal feet to compute the precise geometry of the trapezoidal and triangular roof planes.

Frequently Asked Questions

What is a “Square” in roofing?

In the United States, a “Square” is a unit of area equal to 100 square feet. Roofers use this term to order shingles and underlayment.

How much waste should I add?

For hip roofs, we recommend adding 10% to 15% waste. Hip roofs require more cutting for the corners (hip rafters) compared to gable roofs.
