Installing an asphalt shingle roof is one of the most cost-effective ways to protect a home. The cost depends on the roof area, shingle price per square foot (or square meter), labor charges, and the waste factor.
This calculator helps homeowners and contractors quickly estimate the total asphalt shingle roofing cost with waste considered.
Formula
1. Adjusted Roof Area (with Waste Factor)
Adjusted Area=Roof Area×(1+100Waste Factor (%))
2. Material Cost
Material Cost=Adjusted Area×Shingle Cost per Unit Area
3. Labor Cost
Labor Cost=Adjusted Area×Labor Cost per Unit Area
4. Total Roof Cost
Total Roof Cost=Material Cost+Labor Cost
🧮 Example Calculation
- Roof Area = 2,000 sq. ft
- Shingle Cost per Unit Area = $3 per sq. ft
- Labor Cost per Unit Area = $2 per sq. ft
- Waste Factor = 10%
Step 1: Adjusted Area
Adjusted Area=2000×(1+10010)=2000×1.10=2200
Step 2: Material Cost
Material Cost=2200×3=6600
Step 3: Labor Cost
Labor Cost=2200×2=4400
Step 4: Total Roof Cost
Total Roof Cost=6600+4400=11000
✅ Final Answer: $11,000
