How the formula works
Roof Area = Length × Width × Slope Factor | Total Cost = Roof Area × (Material Cost + Labor Cost) × (1 + Waste/100)
- Roof Area = Length × Width × Slope Factor
- Slope Factors = Low (1.05), Medium (1.15), Steep (1.30), Very Steep (1.50)
- Total Roofing Cost = Roof Area × (Material Cost + Labor Cost) × (1 + Waste/100)
- Material Cost = Roof Area × Material Cost per Sq Ft × (1 + Waste/100)
- Labor Cost = Roof Area × Labor Cost per Sq Ft × (1 + Waste/100)
- Cost per Sq Ft = Total Cost ÷ Roof Area
- Typical material costs: Asphalt ($3-6/sq ft), Metal ($6-12/sq ft), Tile ($8-15/sq ft), Wood ($6-10/sq ft)
- Labor costs vary by region and complexity
