Example Calculation
Example Inputs:
- Roof Size: 2,000 sq ft
- Material Cost: $3.50 per sq ft
- Labor Cost: $2.50 per sq ft
- Removal/Disposal: $1,000
- Extras (vents/flashing): $400
Step-by-Step Calculation:
- Material Cost:
2,000 × $3.50 = $7,000 - Labor Cost:
2,000 × $2.50 = $5,000 - Total Before Extras:
$7,000 + $5,000 = $12,000 - Final Cost:
$12,000 + $1,000 + $400 = $13,400
**Estimated New Roof Cost:
→ $13,400**
