1. What is an Asphalt Roofing Cost Calculator?

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

Purpose: It helps homeowners and contractors budget for roofing projects by calculating material and installation costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total cost ($)
• \( Q \) — Roof area (squares, where 1 square = 100 sq ft)
• \( P_{square} \) — Price per 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 Calculation

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

4. Using the Calculator

Tips: Enter the roof area in squares (divide total sq ft by 100), material cost per square (default $100), and labor costs (default $0). All values must be ≥ 0.
