1. What is Asphalt Replacement Cost per Square Foot?

Definition: This calculator determines the cost to replace an asphalt roof per square foot based on material quantity, price, labor costs, and roof area.

Purpose: It helps homeowners and contractors estimate roofing project costs more accurately.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_{sf} \) — Cost per square foot ($/ft²)
• \( Q \) — Quantity of asphalt squares needed
• \( P_{square} \) — Price per square of asphalt ($)
• \( C_{labor} \) — Total labor cost ($)
• \( A_r \) — Total roof area (ft²)

Explanation: The total material cost (quantity × price) plus labor cost is divided by the roof area to determine cost per square foot.

3. Importance of Accurate Cost Calculation

Details: Proper cost estimation ensures budget accuracy, helps compare contractor bids, and prevents unexpected expenses.

4. Using the Calculator

Tips:

• 1 roofing square = 100 ft²
• Include all labor costs (removal, installation, cleanup)
• Measure roof area accurately (length × width)
• All values must be > 0 (except labor which can be 0)

5. Frequently Asked Questions (FAQ)

Q1: What's included in a "square" of roofing material?
A: One square covers 100 square feet of roof area (10ft × 10ft).

Q2: How do I determine the number of squares needed?
A: Divide total roof area by 100 (e.g., 1500 ft² roof = 15 squares).

Q3: What affects the price per square?
A: Material quality, brand, thickness, and regional pricing differences.

Q4: Should I include disposal costs in labor?
A: Yes, include all associated costs - removal, hauling, installation.

Q5: How accurate is this estimate?
A: It provides a baseline - actual costs may vary based on roof complexity, location, and market conditions.
