1. What is Asphalt Roofing Cost per Square Foot?

Definition: This calculator determines the cost per square foot for asphalt roofing projects by considering material costs, labor expenses, and total roof area.

Purpose: It helps homeowners, contractors, and roofers estimate and compare roofing costs on a standardized basis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C_{sf} \) — Cost per square foot ($/ft²)
• \( Q \) — Quantity of roofing material (squares)
• \( P_{square} \) — Price per square of roofing material ($)
• \( C_{labor} \) — Labor cost ($)
• \( A_r \) — Roof area (square feet)

Note: 1 roofing square = 100 square feet of roof area
