Formulas Used
1. Adjusted Roof Area (Including Waste)
Adjusted Roof Area=Total Roof Area×(1+100Waste Percentage)
2. Material Cost
Material Cost=Adjusted Roof Area×Slate Tile Cost per Sq. Ft
3. Installation Cost
Installation Cost=Adjusted Roof Area×Installation Cost per Sq. Ft
4. Total Slate Roof Cost
Total Cost=Material Cost+Installation Cost
Example Calculation
Let’s say you have the following data:
- Total Roof Area = 1,200 sq. ft
- Slate Tile Cost per Sq. Ft = $9
- Installation Cost per Sq. Ft = $6
- Waste Percentage = 10%
Step 1: Adjusted Roof Area
Adjusted Roof Area=1200×(1+10010)=1320 sq. ft
Step 2: Material Cost
Material Cost=1320×9=11880
Step 3: Installation Cost
Installation Cost=1320×6=7920
Step 4: Total Slate Roof Cost
Total Cost=11880+7920=19800
Estimated Total Slate Roof Cost = $19,800
