1. What is an Asphalt Roof Cost Calculator?

Definition: This calculator estimates the total cost of an asphalt shingle roof based on the roof area in squares and price per square.

Purpose: It helps homeowners and contractors quickly determine roofing material costs for budgeting and planning purposes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total cost ($)
• \( Q \) — Roof area (squares)
• \( P_{square} \) — Price per square ($/square)

Explanation: The roof area in squares is multiplied by the price per square to get the total material cost.

3. Importance of Roof Cost Calculation

Details: Accurate cost estimation helps with budgeting, comparing contractor quotes, and planning roofing projects.

4. Using the Calculator

Tips: Enter the roof area in squares (1 square = 100 sq ft) and the price per square. All values must be > 0.
