Run of hip or valley rafters x Factor (pg. 788) = Total Lineal ft

# of hip rafters x Length x Factor = Total

4 x 12ft = 48 ft

2 x 6ft = 12 ft

2 x 16ft = 32 ft

Total footage = 92 ft x 1.500 = 138 lineal ft of hip rafters

82. D Walker's Building Estimator's Reference Book, 31st Ed. Pg. 789

For hip roofs, the drip edge matches the two-dimensional perimeter plus 10% waste

(58 + 24 + 8 + 36 + 32 +16 + 10 + 12 + 10 + 8 + 10 + 8 + 24) ft = 256 ft x 1.10 = 281.6 ft


Calculate the flat area and then multiply by the factor in the table

Length x Width x Factor ÷ 100 ft2 of roof = # of squares

(58ft x 24ft) + (36ft x 32ft) + (12ft x 10ft) = 2,664 ft2

2,664 ft2 x 1.118 ÷ 100 ft2 of roof = 29.7 or 30 squares


Lineal feet of ridge = 58ft - 12ft - 12ft + 36ft + 10ft = 80ft


Run of hip or valley rafters x Factor (pg. 788) = Total Lineal ft

(2 x 16) + (2 x 6) = 44 ft x 1.5 = 66 lineal ft of valley rafters
