KEY FEATURES

ROOF AREA & PITCH CALCULATION
Calculate roof surface area from building footprint, roof pitch, and overhangs. Supports gable, hip, shed, and flat roof styles. Get accurate squares (100 sq ft) for material ordering.

SHINGLE, UNDERLAYMENT & MATERIAL QUANTITIES
Estimate bundles of asphalt shingles, rolls of underlayment, starter strips, ridge caps, nails, and flashing. Includes waste factor customization. Works with architectural shingles, 3-tab, metal, tile, and wood shakes.

LABOR COST & UNIT RATES
Customize material unit rates and labor costs per square. Long labels display cleanly, and short labels sit two per line for a compact layout. See material cost, labor cost, and total project cost separately.
