1. What is an Asphalt Shingle Roof Cost Calculator?

Definition: This calculator estimates the total cost of a new asphalt shingle roof based on roof size, material price per square, and labor costs.

Purpose: It helps homeowners and contractors budget for roof replacement projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total roof cost ($)
• \( Q \) — Roof size in squares (1 square = 100 sq ft)
• \( P_{square} \) — Price per square of shingles ($)
• \( C_{labor} \) — Labor cost ($)

Explanation: The roof size is multiplied by price per square to get material cost, then labor cost is added.

3. Importance of Roof Cost Calculation

Details: Accurate cost estimation helps with budgeting, financing, and comparing contractor quotes.

4. Using the Calculator

Tips: Enter roof size in squares (measure your roof area and divide by 100), price per square (default $100), and labor cost (default $1500).

5. Frequently Asked Questions (FAQ)

Q1: What is a "square" in roofing terms?
A: 1 square = 100 square feet of roof area. It's the standard measurement unit in roofing.

Q2: What's a typical price per square?
A: Prices range from $80-$150 per square for standard 3-tab shingles, more for architectural shingles.

Q3: How do I estimate my roof size?
A: Measure your home's footprint, multiply by roof pitch factor (1.3 for moderate pitch, 1.6 for steep).

Q4: What affects labor costs?
A: Roof pitch, complexity, location, and time of year can all impact labor costs.

Q5: Does this include removal of old roofing?
A: No, tear-off costs are typically additional. Add 20-30% to labor cost if including removal.
