Corrugated roofing sheets are made of metal, usually steel or aluminum, formed into wavy ridges and valleys. These sheets are popular because they are lightweight, durable, and affordable. The metal is often coated with zinc or other materials to stop rust. Some sheets have plastic or rubber layers added for extra waterproofing. Corrugated metal roofing costs between $5.50 and $11.50 per square foot when installed, according to RubyHome (2025).
What Metals Make Corrugated Sheets?
Steel is the most common metal used in corrugated roofing sheets. It is strong and can handle heavy snow and wind. Steel sheets are coated with zinc, which is a protective layer that stops rust and extends the roof’s life.
Aluminum is another popular choice. It weighs less than steel, making it easier to install. Aluminum does not rust like steel, so it lasts longer in wet climates. Aluminum corrugated sheets cost more upfront but save money over time.

How Long Do Corrugated Metal Roofs Last?
According to RubyHome (2025), metal roofing lasts 40 to 80 years. This is much longer than asphalt shingles, which last only 20 to 30 years. The long lifespan makes corrugated metal a smart choice for homeowners who want a roof that will not need replacing soon.
Maintenance helps metal roofs last even longer. Cleaning gutters and removing debris keeps the roof in good shape. Checking for rust spots and fixing them early prevents bigger problems.
What Coatings Protect Corrugated Sheets?
Metal roofing sheets get protective coatings to stop rust and water damage. Zinc coating is the most common. Some sheets also have paint, rubber, or plastic layers on top. These layers make the roof waterproof and help it shed water faster.
Cool roof coatings are gaining popularity. According to industry data, cool roofs can lower indoor temperatures by nearly 6 degrees Fahrenheit in buildings without air conditioning. Reflective coatings on corrugated sheets help save energy in hot climates.
Why Choose Corrugated Metal Roofing?
Corrugated metal roofing is growing in popularity across the U.S. According to the Metal Roofing Alliance (2024), metal roofing now holds 17% market share in residential roofing. Homeowners choose metal because it is fire resistant, durable, and energy efficient. The wavy shape allows water to drain quickly, which reduces leaks. Metal roofing also works well in areas with heavy snow or hail.
