1. What is an Asphalt Roof Replacement Cost Calculator?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total cost ($)
• \( Q \) — Roof area in squares (1 square = 100 sq ft)
• \( P_{square} \) — Material cost per square ($)
• \( C_{labor} \) — Total 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 Roof Cost Calculation

Details: Accurate cost estimation helps with budgeting, financing, and comparing contractor bids for roof replacement 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 cost (default $1500).
