32×48 Hip Roof Material Calculator
A 32×48 residence with wide 18-inch overhangs has a roof footprint of 35×51 feet (1,785 sq ft). At a 6/12 pitch (1.118 multiplier), the true surface area is 1,996 square feet. Because hip roofs produce triangular offcut waste along 4 diagonal hips, a 15% trade waste factor is applied, requiring 23.0 squares (69 bundles of shingles) and 4 bundles of specialized hip & ridge cap shingles.
Frequently Asked Questions: 32×48 Hip Roof Material Calculator
Why do hip roofs require higher waste factors than gable roofs?
Hip roofs feature diagonal hip rafters running from eave corners to the ridge. Shingle courses must be diagonally bias-cut to meet the hips, generating triangular scraps that cannot be reused on opposing courses.
How many bundles of ridge cap for a 32x48 hip roof?
A 32x48 hip roof at 6/12 pitch features approximately 107 total linear feet of hips and ridge, requiring 4 bundles of hip & ridge cap shingles (33 linear ft per bundle).
