1. What is an Asphalt Roof Replacement Cost Calculator?

Definition: This calculator estimates the total cost for replacing an asphalt roof based on material costs per square and labor charges.

Purpose: It helps homeowners and contractors budget for roof replacement projects by calculating material and labor costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total cost ($)
• \( Q \) — Roof quantity (squares)
• \( P_{square} \) — Price per square ($/square)
• \( C_{labor} \) — Labor cost ($)

Explanation: The roof size in squares is multiplied by the material cost per square, then labor costs are added to get the total project cost.

3. Importance of Accurate Roof Cost Calculation

Details: Proper cost estimation ensures adequate budgeting, prevents project delays, and allows for accurate contractor bids.

4. Using the Calculator

Tips: Enter the roof size in squares (1 square = 100 sq ft), material cost per square, and labor cost. All values must be ≥ 0.
