Pitch factor

pitchFactor = √((12² + rise²) / 12²)

= 1.118 (standard (6/12))

Pitch multiplies the footprint area to get actual roof surface area

2

Actual roof surface area

actualSqFt = footprint × pitchFactor

= 2,000.00 × 1.118

= 2,236.00 sq ft

3

Roofing squares

squares = actualSqFt ÷ 100

= 22.36 squares (24.60 with 10% waste)

1 roofing square = 100 sq ft

4

Material cost

materials = squares × pricePerSquare

= 24.60 × $180

= $4,427

5

Total job cost

total = materials + underlayment + labor + tear-off

= $9,024

$4.51/sq ft of footprint

Key insight

A 6/12 pitch adds ~12% more surface area than the footprint. Hips and valleys add waste — plan 15% for complex roofs, 10% for simple gables. Material cost is typically 40-50% of the total job.
