1. What is an Asphalt Roof Replacement Cost Calculator?

Definition: This calculator estimates the total cost for replacing an asphalt shingle roof based on material and labor costs.

Purpose: It helps homeowners and contractors budget for roof replacement projects by calculating material and labor expenses.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total cost ($)
• \( Q \) — Roof quantity (squares)
• \( P_{square} \) — Price per square ($/square)
• \( C_{labor} \) — Labor cost ($)

Explanation: The roof size in squares is multiplied by the 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 quotes for roof replacement projects.

4. Using the Calculator

Tips: Enter the roof size in squares (1 square = 100 sq ft), material cost per square, and labor cost. All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

A: A square is a unit of measurement equal to 100 square feet of roof area.

Q2: What's a typical price range per square?
A: Asphalt shingles typically cost $100-$200 per square for materials, but premium products can cost more.

Q3: How do I estimate my roof size in squares?
A: Measure your home's footprint and multiply by the roof pitch factor (1.3 for medium pitch, 1.5 for steep).

Q4: What affects labor costs?
