1. What is Roof Replacement Cost per Square Foot Calculator?

Definition: This calculator estimates the cost per square foot for asphalt roof replacement based on material quantity, price, labor costs, and roof area.

Purpose: It helps homeowners and contractors determine the cost efficiency of asphalt roof replacement projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_{sf} \) — Cost per square foot ($/ft²)
• \( Q \) — Quantity of material (squares)
• \( P_{square} \) — Price per square ($/square)
• \( C_{labor} \) — Labor cost ($)
• \( A_r \) — Roof area (ft²)

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

3. Importance of Cost per Square Foot Calculation

Details: This calculation helps in budgeting, comparing contractor bids, and understanding cost distribution for roofing projects.

4. Using the Calculator

Tips: Enter the quantity of material in squares (1 square = 100 ft²), price per square, labor cost, and total roof area. All values must be positive numbers.
