Definition: This calculator compares the total costs of installing metal roofing versus asphalt shingles based on material and labor costs.
Purpose: Helps homeowners and contractors evaluate the cost difference between these two popular roofing options.
The calculator uses these formulas:
Where:
Explanation: The calculator computes total costs for both options and shows the difference to help you make an informed decision.
Details: While metal roofing typically costs more upfront, it lasts 2-3 times longer than asphalt. This calculator helps quantify the initial cost difference.
Tips: Enter roof size in squares, material prices per square, and labor costs for both options. Default values reflect typical market prices.
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: Why is metal roofing more expensive?
A: Metal materials cost more, and installation often requires specialized labor, but it lasts longer (40-70 years vs 15-30 for asphalt).
Q3: What factors affect labor costs?
A: Roof complexity, location, and contractor rates. Metal typically requires more skilled labor.
Q4: Should I only consider upfront costs?
A: No, also consider lifespan, maintenance, and energy efficiency. Metal roofs often save money long-term.
Q5: How accurate are the default values?
A: Defaults reflect national averages, but prices vary by region and material quality. Get local quotes for precise estimates.
