If properly maintained, a zinc roof can last 100 years or more. It forms a coating as it weathers that protects the zinc and reseals if it suffers dings or scratches. Zinc is a naturally occurring material that can actually "heal" itself. The shingle style is lower in cost you’ll pay more for a standing seam zinc roof. Zinc roofing costs $600 to $1,200 per square, installed. Their core material is actually steel and only the coating contains tin in a zinc/tin or lead/tin alloy.

Tin roof installation costs $500 to $1,200 per square. For example, stainless steel is on the Chrysler Building in New York City. Stainless steel is a durable, corrosion- and rust-resistant alloy with an excellent track record. Stainless steel roofs cost $1,000 to $1,600 per square, installed. These roofs are low-maintenance and energy-efficient, but they aren’t as corrosion-resistant. This makes them more expensive than galvalume (but less expensive than stainless steel). Galvanized steel roofs have a steel core and a zinc coating for rust resistance. Galvanized steel roofs cost $750 to $1,000 per square, installed. You can get galvalume in a variety of colors, but it’s subject to fading. This rust-resistant, highly pliable roof is the lowest-cost option for steel roofs. Galvalume steel roofs cost $600 to $900 per square, installed. Various steel types include galvalume, galvanized, and stainless steel. Steelĭepending on the type of steel, a steel roof cost can range from $600 to $1,600 per square. Over time, it develops a corrosion-resistant patina. That said, copper is long-lasting ( 100+ year lifespan), low-maintenance, and resistant to rust. A 3,000-square-foot project with the most expensive copper material in the most expensive labor market could theoretically cost more than $90,000, but a 2,000-square-foot copper roof project costs an average of $42,000.Ĭopper is difficult to work with and demands professional installation. CopperĬopper roofing costs between $1,500 and $3,000 per square. They can keep utility costs down thanks to their high natural reflectivity in fact, aluminum is among the most energy-efficient roofing materials. Aluminum roofs can last 45 years and are recyclable and highly pliable. You can get aluminum in sheet or shingle form. For a 2,300-square-foot home, an aluminum roof could cost from $9,200 to $25,300, but a smaller 1,000-square-foot home could cost as low as $4,000 installed.

The most common widths are 24″ and 36″ exposed, but the actual width of the panel will be larger to accommodate an overlap. The most common lengths are 8′, 10′, 12′, and 16′, however many distributors will cut to length. Roofing panels come in many styles and dimensions with different overlap dimensions. Consider ordering a few extra panels to account for more cuts and waste. It’s a good idea to order an extra 10% to account for cutoffs and waste material.įor more complex roofs with many peaks and sections, find the square footage of each roof section and add them all together to find the total square footage. Panels are often measured in inches, so you can use our inches to feet conversion calculator to convert to feet.įinally, divide the square footage of the roof by the square footage of the metal roofing panel to find the number of panels needed for your roof. Measure the length and width in feet, then multiply together to find the square footage. Next, find the square footage of the metal roofing panels you want to use.
