The most popular metal shingles are made from which material and thickness?

• A. 0.02" thick aluminum
• B. 0.04" thick aluminum
• C. 0.02" thick copper
• D. 0.03" thick steel

Answer: (A)

Aluminum around 0.02 inches thick is the standard for residential metal shingles because it gives a great balance of light weight, corrosion resistance, and ease of fabrication. That thin yet sturdy gauge provides enough rigidity to shed water and resist denting while keeping the roof load low and installation efficient. In Florida, the corrosion resistance of aluminum is particularly beneficial in humid, coastal environments, helping the shingles hold up against salt spray and humidity without a heavy, costly metal. Thicker options, like 0.04" aluminum or copper, add cost and weight without delivering a proportional benefit for most homes, and steel at 0.03" requires coatings to prevent rust. So the most common choice is aluminum at about 0.02" thick.
