1. What is an Asphalt Roofing Cost Estimator?

Definition: This calculator estimates the total cost of asphalt roofing projects based on roof area, material price per square, and labor costs.

Purpose: It helps homeowners, contractors, and roofing professionals budget for asphalt roofing projects.

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)
• \( C_{labor} \) — Labor cost ($)

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

3. Importance of Roofing Cost Estimation

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

4. Using the Calculator

Tips: Enter the roof area in squares (1 square = 100 sq ft), price per square (default $100), and labor costs (default $0). All values must be ≥ 0.
