When it comes to roofing, the word “metal” covers a lot of territory. Metal roofing is produced from a variety of materials, including steel, aluminum, stainless steel, copper, and zinc alloys. Of course, each one of these has clear differences that affect durability, price, appearance, and more.
Steel and aluminum are by far the most commonly available metal roofing materials. Both are relatively economical, durable, and hold paint finishes well.
Most metal roofing is made from steel, which is heavier and sturdier than aluminum (though some metal roofing material is called “steel roofing,” it may be made from any of several materials, including alloys). The gauge of the steel affects its performance and durability. Two common gauges of steel roofing are G-60 and thinner-gauge G-90. The latter is less expensive and typically used for low-end corrugated and ribbed metal roofing panels.
Galvanized and Galvalume® coatings are both considered “substrates.” Galvanize is zinc and Galvalume® is a combination of zinc and aluminum. Though galvanized coatings were once the best answer, a large percentage of today’s metal roofs utilize Galvalume® because it is two to four times more effective at resisting corrosion. It doesn’t, however, hold up well in coastal climates because of corrosion from salt air. Similarly, it isn’t recommended for use on roofs at farms where manure is prevalent. Ammonia gas created by manure reacts with the coating, breaking it down.
Galvalume® is more expensive than hot-dipped zinc galvanize, but lasts longer. It’s usually used with thick G-90 steel. Galvalume® is typically warranted for 20+ years.
Both Galvalume® and galvanized finishes are typically painted or coated with a durable top coat.
A coating of epoxy primer offers adhesion and a baked-on acrylic top coating adds color and protection. Because some sheet systems are designed for commercial applications, they are generally given highly durable paint finishes. One popular fluorocarbon coating used on many products is called Kynar 500.
Another finish applied to roofing tiles is stone coating, which mimics the look for tile roofing. This is a premium surface.
Aluminum is a very lightweight, relatively soft metal, so it is more prone to denting and damage than steel, and it isn’t as rigid as steel. On the other hand, aluminum won’t rust or corrode the way steel can if the finish is compromised. For appearance, it’s almost always painted or coated similarly to steel.
Aluminum roofing may be a better choice in coastal areas because aluminum doesn’t rust the way steel can.
Environmentalists express concerns about using aluminum for purposes such as roofing because of the tremendous amount of energy required to produce it. (See Aluminum Production and Environmental Impact.) This stated, when an old aluminum roof is removed, it can be completely recycled.
Other metal roofing materials are also available, but can be prohibitively expensive. These materials provide stunning roofs on high-end homes. Briefly, here are three types:
Copper metal roofing, rooted in centuries of use, will not rust, has no “finish” to scratch or peel, is soft enough to easily tool, and weathers naturally to a beautiful verdigris patina. A copper roof is likely to outlive the house it covers—copper roofs can last hundreds of years. Even better, copper is easily (and valuably) recycled.
Unfortunately, copper is extremely expensive. For this reason, it tends to be used for roof details such as covering a cupola or bay window rather than to cover an entire roof. Expect to pay about $1800 per square (100 square feet) for labor and materials or $900 to $1400 per square for materials only.
Alloy roofing products are formulated for strength, graceful weathering, and durability. Cost depends on the specific material, but, as a group, alloys are pricey—starting at about $1800 per square (100 square feet) for labor and materials.
Stainless-steel roofing, a very expensive roofing material, won’t rust or corrode. Terne coating, a zinc-tin alloy, can give stainless steel a natural matte-gray finish.
An important early decision when considering a metal roof, is to determine the look you want the roof to have. Residential metal roofing comes in two basic forms: sheet-like panels and shingles. In most cases, these two forms have very different appearances and characteristics. Within these two broad categories, many variations, colors, and patterns are produced…more about that later.
The most familiar patterns of panel-style metal roofing are standing-seam roofing and batten roofing. These have raised ribs that run vertically along the panels every 6, 9 or 12 inches. The panels are applied vertically on a roof.
These types of roof don’t attempt to look like anything other than what they are: metal roofing.
The two main systems are named after the method of joining panels together. Here we discuss them together under the term “standing-seam metal roofing,” but there are slight differences.
Standing seam roofing has self-sealing, raised ribs along the panel edges that interlock to provide a tight seal to effectively seal-out and shed water.
The standing seam ribs are generally about 3/4- to 1 1/2-inch high and 1/2- to 3/4-inch wide. Various locking systems are sold, each varying in appearance, ease of use, effectiveness in sealing, and the ability to be used on special roofs (such as curved ones). Most manufacturers make several varieties.
Batten roofing employs a wider cover cap—typically about 2 1/2 inches wide. Special matching metal parts are made for ridges, hips, edges, and connections.
Standing seam and batten sheets are sold in many sizes. The most common sizes are 3 feet wide by 6, 8, 10, 12, 14, and 16 feet long, but you can also get custom sizes. Because of the panels’ large sizes, they’re quicker to install than shingle systems and they work best on large, unbroken expanses.
This type of roofing’s decidedly commercial look is favored by architects for its honest, clean, contemporary appearance. It is commonly used on homes ranging from mountain cabins to modern masterpieces but would look very out-of-place on a Colonial home.
Metal roofing sheets begins as “flat stock” (flat metal panels) that roofing manufacturers or fabricators form into roofing panels and components. The biggest manufacturers also apply a very durable finish.
Some metal roofing installers fabricate flat stock into roofing materials on-site; of course, this requires the proper forming equipment. Problems with this method are wide variations in the quality of the work, limited possibilities for finishes, and usually very limited warranties (one year or less). With site-formed roofing, you also don’t have the reliability of a large manufacturer behind the product.
Manufactured sheet metal roofing is sold in large panels—normally 26-gauge coated steel that weighs about a pound per square foot. Other materials include painted aluminum, solid copper, zinc alloys, and terne-coated stainless steel.
Metal roofing prices per sheet are generally determined by the square foot or by the square, which is 100 square feet. Prices vary widely, depending on the material and finish, ranging from a low of about $1.50 per square foot to about $6 per square foot. Figures typically include panels, fastening clips, caps, and all trims and flashing. If you ask for ballpark square-foot prices, be sure they’re inclusive of all necessary parts.
