1. What is an Asphalt Shingle Roof Repair Cost Calculator?

Definition: This calculator estimates the total cost to repair an asphalt shingle roof based on repair area, material costs, and labor charges.

Purpose: It helps homeowners and contractors budget for roof repairs by providing accurate cost estimates.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total repair cost ($)
• \( A \) — Repair area (square feet)
• \( C_{sf} \) — Material cost per square foot ($/ft²)
• \( C_{labor} \) — Fixed labor cost ($)

Explanation: The repair area is multiplied by material cost per square foot, then the fixed labor cost is added to get the total repair cost.

3. Importance of Accurate Roof Repair Estimates

Details: Proper cost estimation helps in budgeting, prevents unexpected expenses, and ensures you get fair quotes from contractors.

4. Using the Calculator

Tips: Enter the repair area in square feet, material cost per square foot (default $12.25), and labor cost (default $150). All values must be ≥ 0.
