If you are looking for a roof that can give your home an exquisite, modern look coupled with superb durability and longevity, a standing seam metal roof is the perfect system to meet your needs. Standing seam roofs are quickly gaining in popularity among discerning homeowners who want to invest into an environmentally-friendly, premium quality roofing system that offers a true peace of mind for many decades to come.
A standing seam roof is a metal roofing system, where continuous interlocking panels run from the ridge of the roof all the way down to the eaves. The upturned edge of one metal panel that connects it to adjacent panels creates distinctive vertical lines and a trendy, modern look. Most of residential standing seam metal roofing systems are designed as watershed systems, requiring a minimum roof slope of 3:12 (14 degrees) or greater.
Residential standing seam panels are generally 12 to 19 inches wide. They are typically made out of painted galvanized steel/G-90 Steel, galvalume steel (offers greater protection from corrosion than galvanized steel), or painted aluminum. It is also possible to order panels made out of copper, or zinc, but these premium metals are more expensive, and are not a typical material choice for most homeowners.
Standing seam roofing panels can either be pre-formed at a manufacturing facility or a sheet metal shop, or site-formed. Site-formed panels are formed from a roll of metal coil, which is fed through special equipment which crimps the metal into rigid panels. Forming standing seam panels right on the job site offers the advantage of speed, convenience, and makes it possible to form panels of considerable length that would otherwise be difficult to transport.
A common type is a snap-lock standing seam, which locks the panels together when one side is adjoined with the one next to it.
Standing seam metal roofs boast a number of advantages that make them the fastest growing metal roofing choice among homeowners.
Great Curb Appeal: for people who want a modern look for their home, a standing seam metal roof is an ideal choice. Sleek lines of the roof, give the house a very cool contemporary feel and multiple combinations of panel widths, seam profiles, and rib heights offer design flexibility. The many sizes and styles of standing seam metal roofs allow for an array of beautiful visual effects.
Durability and Longevity: Standing seam metal roofs are famous for their exceptional durability and longevity. This roof will not crack, shrink, erode, or perforate. It offers superior protection against fire and strong wind. You will have real peace of mind with a standing seam metal roof, as it will last over 50 years, requiring virtually no maintenance.
Impervious to Moisture: seams are the weakest point in any roof, often becoming the potential entry point for leaks. In a standing seam metal roof, seams are raised above the level of the roofing panel, making their impervious to moisture. Also, standing seam metal roofs have less seams in total than other types of roofs.
Sustainable: increasing numbers of homeowners today are looking for a green roofing solution. A standing seam metal roof is one of the few truly environmentally friendly roofing systems on the market. Since it is made of metal, the roof is completely recyclable, and standing seam metal roofs also contain recycled metal content. Moreover, a standing seam metal roof’s cool reflective properties will help you reduce energy waste and realize significant saving on your electric bill throughout the year.
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.
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.
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.
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 to consider.
Cost. The biggest drawback is initial cost. 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.
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.
How Expensive is it?
It is important to realize that a number of factors will determine a final price of a standing seam metal roof. First, the cost of materials may vary quite a bit based on the type of material, and from supplier to supplier. This means that you should do your research and get quotes from different suppliers to ensure that you are getting the best deal. The price per square foot will also depend on the total square footage needed for your project. The larger your overall roof area, the less it will cost per sq. foot of material.
Note, that the cost of labor for a standing seam metal roof will be relatively high due to a requirement that a standing seam roof is installed by specially trained installers who have the right skills, a technical know-how, and the right tools to do the job.
For an average size standing seam metal roof, you can expect to pay anywhere from $1,000 to $1,500 per 100 sq. feet, which should include materials, labor, and warranty.
