1. What is this Roofing Cost Comparison Calculator?

Definition: This calculator compares the total costs of steel roofing versus asphalt shingles for a given roof size.

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:

• \( C_s \) — Total steel roofing cost ($)
• \( C_a \) — Total asphalt shingles cost ($)
• \( Q \) — Roof size in squares (1 square = 100 sq ft)
• \( P_{square\_s} \) — Steel price per square ($450–$1700)
• \( P_{square\_a} \) — Asphalt price per square ($300–$700)
• \( C_{labor\_s} \) — Steel roofing labor cost ($)
• \( C_{labor\_a} \) — Asphalt shingles 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 accurately and understand the price difference between premium (steel) and standard (asphalt) roofing options.

4. Using the Calculator

Tips: Enter roof size in squares, material prices per square (default values provided), and any additional labor costs. All values must be ≥ 0.

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 for roofing materials.

Q2: Why is steel roofing more expensive?
A: Steel lasts longer (50+ years vs 20-30 for asphalt), is more durable, and provides better weather resistance.

Q3: Are labor costs typically different?
A: Yes, steel roofing often requires more specialized installation, increasing labor costs by 20-50% compared to asphalt.

Q4: What factors affect material prices?
A: Steel prices vary by gauge and finish; asphalt prices vary by shingle quality and warranty length.

Q5: Which is better for my home?
A: Consider budget, climate, home style, and how long you plan to stay. Steel offers long-term value; asphalt has lower upfront cost.
