Calculate optimal crew size and labor costs with rates you configure
Required. Enter roof area in square feet, not lineal feet. ≈ 25 roofing squares
Production rate basis: 1200 sq ft/day is per 4-person reference crew, 8-hr workday.
Scope basis: default replacement scope: tear-off, underlayment, shingle install, flashing, and cleanup; ridge vent only when selected. Current selected scope = Tear Off, Underlayment, Shingle Install, Flashing, Cleanup (2.4 hrs/square before complexity and crew productivity).
Required planning target. Use whole project days.
Auto crew formula: ceil((25 squares x 2.4 hrs/sq x 1.3 complexity) / (3 days x 8 hr/day)) = 4 required workers; selected template = 5 workers.
