Metal Shingle Roofing

Metal shingles are manufactured to resemble wood shakes, Spanish and mission tile, slate, and Victorian metal tiles. Most are made from painted or coated steel or aluminum that has been pressed or formed into realistic shapes.

Some metal shingle roofing materials are amazingly convincing in appearance. Producers of painted metal products reduce tell-tale sheen by texturing the metal, layering the finish, and giving granulated-stone topcoats. These products, typically tile or slate lookalikes, are hard to distinguish from the real thing.[GARD align=”left”]

Metal shingle systems are manufactured in large panels (typically about 4 feet long), designed for quick installation, or as single shingles meant to be applied individually. Most panel types can be installed over one or two layers of existing roofing; the individual type requires tear-off so it can be applied to a firm, flat roof deck.

Residential roofing contractors are the tradespeople who install metal shingle systems, though many who install wood, tile, asphalt, and other more conventional products don’t install metal. Because metal roofing requires slightly different techniques, some manufacturers or distributors require metal roofing contractors to be accredited by taking a few factory-taught classes before they will allow their contractors to install their products.

Here are a few popular brands of metal shingle systems:

Gerard roofing is actually galvanized steel with a tile-colored finish of stone granules made in two patterns, facsimile shake and tile, and a variety of colors. The stone-finished shingles run from $3 to $4 per square foot or more if tear-off is required.

Decrabond, by Carter Holt Harvey, is a tile facsimile with a granulated-stone finish. Unusually shaped Colortile, by the same manufacturer, is galvanized steel with a baked-on acrylic finish (actually a series of seven coatings). Though available in only six standard colors, custom colors may be special-ordered subject to a minimum order size.

Met-Tile, made from painted 26-gauge galvanized steel, is a tile lookalike that ranges from $1.65 for panels only to $3.20 per square foot for a complete package (materials only); most applications run about $3.

 

Prestige Copper Shingles from Petersen Aluminum Corporation are made up of real copper bonded to an asphalt-shingle base. They offer the elegant look of a real copper roof at about one-third the price ($5 to $7 per square foot, materials only).

Zappone manufactures aluminum and copper shingles shaped to resemble wood shakes. About half of the shingles sold are owner-installed-a relatively simple but time-intensive job. Material pricing runs from $1.75 to $4 per square foot for aluminum and from $4 to $7 a square foot for copper, depending on the roof’s complexity (the number of accessories needed dramatically affects cost).[GARD align=”right”]

You can install copper accents without putting on an entire copper roof by ordering copper ridge caps, drip edges, valleys, or other accessories and combining them with a different roofing material such as wood shingles. Zappone also manufactures half-sized copper shingles for use on bay windows, cupolas, gazebos, and the like. You can shingle a bay window with these for less than $300.

 

Alcoa makes two varieties of aluminum shakes that resemble wood shakes and slate or tile. Both may be applied over up to two layers of some existing roofing materials. Alcoa offers a lifetime, non-prorated limited warranty that’s transferable when you sell the house.

Standing Seam Sheet Metal Roofing

Standing seam sheet metal roofing has become popular for residential roofing. It is a sleek, stylish roofing for vacation homes, contemporary homes, and more.

Sheet metal roofing  begins as “flat stock” (flat metal panels) that roofing manufacturers or fabricators form into roofing panels and components. With many types, manufacturers also apply a 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. Because of the large panel size, this roofing works best on large, unbroken expanses.

Types of Sheet Metal Roofing

The two main systems are named after the method of joining panels together: “Standing-seam roofing” has a self-sealing, raised seam, and “batten roofing” employs a wider cover cap. Special matching metal parts are made for ridges, hips, edges, and connections.

Sheet metal roofing materials are typically priced by the square foot. 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.

To get bids, begin by calling the manufacturer, who will usually put you in touch with a local representative or installer who will bid (or arrange for several roofers’ bids) on your job. Be sure to clarify whether or not labor and freight are included in the price. Because freight can be very expensive, it usually pays to choose a manufacturer in your region.

Brands of Sheet Metal Roofing

Here’s a closer look at some popular brands of sheet metal roofing. Depending on your geographical region, prices may vary significantly from those given here; the best way to get precise prices is to request bids.

* Microzinc Roofing System from W.P. Hickman is manufactured from a zinc-copper-titanium alloy in both standing-seam and batten systems. This metal weathers naturally, developing a gray patina in six to 18 months. It’s beautiful and very expensive; materials run from about $4 to $6 per square foot, depending on quantity and freight.

* Follansbee Steel terne-coats standing-seam roofing for ease of soldering during construction and excellent paint adhesion. On standard steel, this finish, a mixture of 80 percent lead and 20 percent tin, must be painted. But on stainless-steel panels, it can be left to weather naturally (stainless steel doesn’t rust). Stainless-steel terne-coated roofing is both durable and beautiful; with oxidation, terne coating transforms from a shiny metallic finish to a matte gray. This type of roofing material runs about $3 per square foot plus installation. The lead content of the terne coating is a concern to some. Gloves are recommended for installers to protect against lead poisoning. During initial oxidation, some lead washes off the roof, and traces may be detected in the soil around the structure.

* Berridge offers a wide variety of metal roofing and siding materials. Of these, the Victorian and classic shingles, prefinished or unfinished in Galvalume, are particularly interesting. These shapes are especially appropriate for older-home restorations.

The word “metal” covers a lot of ground when it comes to metal roofing materials. Steel, stainless steel, aluminum, copper, and zinc alloys are all materials used for metal roofing. Each has different properties that affect durability, price, and appearance.

Conventional Metal Roofing Materials

By far, the most common materials used for metal roofs are steel and aluminum.[GARD align=”left”]

Steel, used for most metal roofing, is heavier and sturdier than aluminum. Manufacturers have settled on a number of durable coatings and finishes that protect steel from rust and corrosion. Steel is usually zinc-coated for corrosion protection and then sealed. A coating of epoxy primer offers adhesion and a baked-on acrylic top coating adds color and protection. Because sheet systems are designed for commercial applications, they generally are given highly durable paint finishes. One popular fluorocarbon coating used on many products is called Kynar.

Aluminum, extremely lightweight, is used for some residential metal roofing. It won’t rust, but it must be painted or coated for appearance. Coatings are similar to those used on steel. Aluminum is a very soft metal, so it dents and mars easily and isn’t nearly as rigid as steel. Environmentalists have expressed concerns about using this precious resource for purposes such as roofing.

High-End Metal Roofing Materials

Other forms of metal roofing are also available, but can be very expensive. They provide stunning roofs on high-end homes.[GARD align=”left”]

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. Unfortunately, it’s extremely expensive.

Alloy roofing products are formulated for strength, graceful weathering, and durability. Cost depends on the specific material, but, as a group, they are pricey.

Stainless-steel roofing, a very expensive roofing material, won’t rust or corrode. Terne coating can give it a natural matte-gray finish.

Pros & Cons of Metal Roofing

This is an unbiased, expert look at the benefits and drawbacks of steel and other metal roofing materials.
[GARD align=”left”]

Metal roofing is great in snow country because it is fire resistant, lightweight, and excellent at shedding snow.

[/media-credit] Metal roofing is great in snow country because it is fire resistant, lightweight, and excellent at shedding snow. The panels are applied over dense foam insulation to maintain high R-values. Dark surfaces warm in the sun to aid in quickly melting snow.

If you are considering buying metal roofing for your home, it’s important to weigh the pros and cons of metal against other more common roof materials, such as asphalt, wood, and tile. Here is a close look at some of the benefits and drawbacks of steel, aluminum, and other metal roofing.

Metal Roofing Benefits

Metal beats out conventional roofing materials on a number of different counts:

Expected life. Properly installed, a metal roof should last as long as the house, sealing out water, surviving high winds, and easily shedding snow. Metal is resistant to fire, mildew, insects, and rot. Warranties vary widely, but most companies back their products for 20 to 50 years. Paint finishes typically have a 30-year limited warranty.

Weight. Compared with tile at 750 pounds per square (an area equal to 100 square feet) or concrete tile at 900 pounds per square, metal roofing is lightweight. Most varieties run from 50 to 150 pounds per square.

sheet metal roofing benefits

Sheet-metal roofing is lightweight, fire-resistant, quick to install, and great at shedding water and snow.

Some types of metal roofing materials may be applied over an existing roof without the need for tear-off or additional structural support. In fact, if you’re building a house or an addition, you can often downsize or reduce the number of roof support members.

Speed & ease of roofing installation. Most metal roofing materials come in multiple-shingle sections or in 12- to 36-inch-wide panels. An accomplished contractor can install these quickly. If your roof is stripped off and a storm is on the way, shortening the process by a day or two may prove to be a critical advantage.  Because of the material’s light weight, you can save on engineering and building the supporting structure.

Fire resistance. Because metal roofs are noncombustible, they’re given a Class A fire rating (the most resistant). Part of a roof’s classification depends on materials beneath the surface that could ignite in intense heat. Most metal roofs applied over a combustible material such as wood shingles have a lower, Class C rating.

Heat conduction. Metal reflects radiant heat from the sun, minimizing midday heat gain. This means you save energy needed for air conditioning during the day. Though the material itself is low in insulation R-value, many systems utilize a dead-air space between the metal and roof deck to increase energy efficiency.

Minimal roof pitch. Most metal roofing materials can be installed on gently pitched roofs without presenting a leaking potential. Minimum roof pitch is 3-in-12 (the roof rises 3 inches for each horizontal foot).

Maximum shedding of rain and snow. Metal roofing is practically impervious to rain and snow because of the way it is designed to interlock and because the surfaces are hard and slippery.

Metal Roofing Drawbacks

Though metal roofing offers many pluses, there are a few drawbacks worthy of mention. For the most part, metal roofing manufacturers have improved their products to address or solve many of these concerns:

Cost. The biggest drawback is initial cost. Metal roofing is equivalent in cost to other premium materials—from about $150 to $600 per square (100 square feet). Because of the material’s long-term durability, the trick is that you ultimately save the difference (and more) if you stay in the house for a long time and, of course, you save on seasonal maintenance. Of course, if you plan to move in a couple of years, you probably won’t get the return on your investment.

Noise. For some, the sound of rain tapping on the roof is romantic and homey; for others, it’s like living inside a drum. In a rainstorm or hailstorm, living beneath thin sheets of metal is bound to be noisier than living beneath thick slate or tile. Noise can be controlled both by using materials that have structural barriers to minimize the drumming effect and by applying them over sound-deadening insulation and solid plywood sheathing.

Denting. Just as your car will dent if a golf ball hits it, a metal roof can dent if large hailstones fall on it. Aluminum and copper, much softer than steel, are more prone to denting. Some types are guaranteed not to dent, however.

Though you shouldn’t have to walk on a roof that doesn’t leak, there may be occasions when a plumber needs to snake out a vent pipe or a chimney sweep needs access to the flue. You can walk on some metal roofs but not all; it depends on how the particular product is made and the type of construction supporting it. As you might imagine, metal can be very slippery when wet.

Marring & care. Some painted metal roof finishes can peel, chip, fade, scratch, or chalk, although nearly all are guaranteed for 30 years. Walking on some types, particularly those with a granulated-stone surface, may cause wear. Installers must be careful not to scratch or dent the roofing during installation, and panels must be treated with care. Unlike conventional roofing, some metal shingle systems are installed from the top down, eliminating the need to walk on them. Once installed, it may be necessary to hose off roofing now and then to keep it looking good.

Expansion & contraction. Because metal expands and contracts as it warms and cools, most new products have fastening systems that accommodate movement; otherwise, fasteners that secure the roofing tend to come loose. Expansion and contraction on hot days can cause a wavy affect.

Modifications. Metal roofing materials installed in large panels are more difficult to replace if damaged than individual shingles. Also, if you remodel or add on to your home 10 or 20 years from now, it may be difficult to match the material.

Lightning. Many people assume that because metal conducts electricity it also attracts it. This really isn’t the case, and there are many documented instances of lightning striking trees or other high objects located near metal roofs rather than the roofs themselves. Just the same, if desired, metal roofs can be easily grounded by a lightning protection company.

hire metal roofing contractors

Most types of metal roofing require professional installation.

Because a new roof is a major investment and something you’re likely to live with for a long time, it’s important to choose your roofing contractor carefully.

This holds true for all types of roofing contractors but is even more important with metal roofing contractors because application of a metal roof is a specialty that requires skills and tools that are quite different than those used for installing more-typical roofing products. Whereas a typical roofing contractor can install wood or asphalt shingles, it takes a specialist to install mot types of metal roofing.

Tips for Hiring Metal Roofing Contractors

For sheet metal roofing systems, choose a contractor who has had at least three years of experience installing metal roofs.[GARD align=”left”]

The best way to find a good metal roofing contractor is through friends and neighbors who have had similar work done. Unfortunately, because metal roofs are uncommon, you may not know anyone who has had one installed. In this case, your best bet is to use one of the Web’s contractor-finding sites such as HomeAdvisor. The benefit of these services is that they help you find local metal roofing contractors who have gone through a pre-screening process.

Another route for finding metal roofing specialists is to call architects or builders who have designed or built homes utilizing metal roofs and ask them for their suggestions.
