1. What is a Roofing Cost Comparison Calculator?

Definition: This calculator compares the total costs of installing a metal roof versus asphalt shingles.

Purpose: It helps homeowners and contractors make informed decisions about roofing materials based on cost.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( C_m \) — Total metal roof cost ($)
• \( C_a \) — Total asphalt shingle cost ($)
• \( Q \) — Roof size in squares (1 square = 100 sq ft)
• \( P_{square\_m} \) — Metal roofing price per square ($)
• \( P_{square\_a} \) — Asphalt shingle price per square ($)
• \( C_{labor\_m} \) — Metal roof installation labor cost ($)
• \( C_{labor\_a} \) — Asphalt shingle installation labor cost ($)

Explanation: The calculator multiplies roof size by material cost per square, then adds labor costs for each option.

3. Importance of Roofing Cost Comparison

Details: Comparing costs helps budget for roofing projects and understand the price difference between premium (metal) and standard (asphalt) options.

4. Using the Calculator

Tips: Enter roof size in squares, material prices per square (default $350 for metal, $120 for asphalt), and labor costs (default $1500 for metal, $1000 for asphalt).

5. Frequently Asked Questions (FAQ)

Q1: What is a "square" in roofing terms?
A: One square equals 100 square feet of roof area, the standard measurement unit in roofing.

Q2: Why is metal roofing more expensive?
A: Metal costs more initially but lasts 2-3 times longer than asphalt, often making it cheaper long-term.

Q3: How do I estimate my roof size in squares?
A: Measure your roof's square footage (length × width) and divide by 100.

Q4: Are labor costs significantly different?
A: Yes, metal roofing typically requires more specialized installation, increasing labor costs.

Q5: Which is better for my climate?
A: Metal excels in snowy areas (sheds snow easily) and fire-prone regions, while asphalt works well in most temperate climates.
