It is used as the roofing and facing on large office buildings and skyscrapers including the Chrysler Building in New York City because it holds up well to weather and remains glossy and attractive. It can suffer from corrosion and may require some additional maintenance and recoating. Galvalume also features a steel core but is covered with a material that is a combination of zinc and aluminum.
Galvalume is available in many colors although without regular resealing, colors can fade and is quite flexible compared to other materials, so it can be helpful in applications where curves or shaping are necessary. Tin used to be a common roofing material, especially in situations where waterproofing was important.
Today, most tin products are actually a steel core with a tin and zinc or tin and lead coating called Terne.
Naturally reflective, flexible, and recyclable, aluminum is one of the most naturally energy-efficient materials you can choose for your roof. Copper has a rich natural beauty, and combined with its long, low-maintenance lifespan and rust-free properties, this material is one of the most expensive roofing materials you can choose.
Zinc is used as a coating for other metal roof materials but can also stand alone as a covering. Zinc forms its own coating as it ages and oxidizes and has the unique quality of healing itself and reseal dents and scratches when they occur. Most lead roofing features a copper or other metal core and a lead coating to cut down on the weight without losing the insulation value of the material.
Lead installs well on flat and highly pitched roofs, resists corrosion, and develops a deep and beautiful patina. The rust layer actually protects the steel core while looking charmingly rustic. This choice is not ideal for coastal areas; while the roof will repel water, snow, hail, and other weather, the blowing saltwater near the ocean will cause the rusted metal to deteriorate quickly.
Most of the material types are available in sheet form. Sheet metal comes in different gauges, or thicknesses, for various applications. The lower the gauge, the thicker the metal is.
Most sheet metal for commercial and residential roofing averages between and gauge. These roofs are installed with exposed fasteners, creating a rustic look. They can be painted or left unpainted. The metal can be pressed into different styles, and ribbed, corrugated, and crimped are common styles. Metal roofs can be constructed by pressing shingles, shakes, or tiles for a more traditional roof appearance with less maintenance than wood, stone, or asphalt shingles.
The shingle-style strips are called modular press-formed granular or stone-coated and are made from gauge steel and stamped with a texture that looks like a traditional asphalt shingle.
Other press forms include metal Spanish tile, which is lighter and less costly than real Spanish tiles, and a metal slate, which has the appearance of real slate but is far lighter, easier to maintain, and less expensive.
These options provide a more traditional roof while maintaining the efficiency, cost, and durability of a metal roof. In addition, they can help sidestep some homeowners associations that prohibit vertically striped traditional metal roofs.
Slightly more expensive to install than sheet metal roofing, a shingle or shake roof can last as long as 40 years with minimal maintenance and is far more resistant to corrosion and leaks than panels. This style allows for expansion and contraction of the metal in heat and cold without cracking or stressing the metal.
Constructed from galvanized or Galvalume steel, aluminum, copper, or zinc, standing seam roofs have a modern farmhouse look. They are available in to gauge metal for commercial applications and to gauge pieces for residential. They can be attached with invisible clip fasteners or exposed fasteners. These panels are constructed by folding the edges of two panels together to hook together, creating a mobile yet watertight seam.
Some snap together, while others simply fold, creating an attractive vertical pattern on the roof. Send feedback to the editorial team. Rate this Article.

And look at the bottom line totals! Consequently, when you look at cost through the lens of the life cycle instead of first costs, metal roofing paints a clear picture. Much like the printer option we discussed earlier, the higher first cost metal roof products become the lower-priced options once the shorter life expectancy, tear off, and replacement costs for shingle roofs are included in the life cycle cost equation.
While metal roofing tells a compelling life cycle cost story, a few other topics bear consideration in any cost analysis between shingles and metal roofing. Since savvy buyers typically consider the roofing condition before making an offer, you may be able to sell your home for a higher price to offset the additional investment of metal roofing.
However, to an uneducated buyer, the house may not be worth any more than if it had a shingle roof with years of life expectancy remaining. Consequently, Remodeling magazine indicates you can expect to recoup With that said, as consumer education increases, metal roofing continues to gain market share each year, while shingle roofing continues to lose market share each year.
Consequently, as consumer awareness and buying habits shift away from shingles and towards metal, homeowners reasonably expect a metal roof to increase the value of their home.
Reduced Maintenance: Metal roofing requires much less maintenance than shingle roofs. Historically most homeowners simply accepted that after storms, hail, and high winds, they should expect a roof replacement or, at the very least, some moderate repairs.
Conversely, metal roofing systems are inherently less prone to damage from Mother Nature because they are engineered to withstand high winds. Are you interested in learning more? Check out these articles about the performance of metal roofs in high wind and hail-prone areas. Again, that is a significant amount to most homeowners. Bottom line: Admittedly, when comparing bids between shingles and metal roofing, the metal roofing will be more expensive from a first cost standpoint.
Yet once lower life cycle costs, reduced maintenance, and energy savings are factored in, metal roofing truly has a great story to tell. But beyond that, product selection, aesthetics, and installation costs are also dominant factors. Product Type: The broad type of product selected and the family of products within that category significantly impact the cost of any roofing project.
For example, there are two predominant types of metal roofing: concealed fastener and exposed fastener panels. The product and installation costs vary significantly between the two styles. The steel and tin molecules rapidly vibrate, interlock, and bond due to heat making your tin roof durable and resistant to cracking. The life expectancy of tin is for up to 40 years and it is eco-friendly as tin is made from 30 to 60 percent recycled materials.
Zinc metal roofs have been around for more than years now. Zinc is an easily foldable material which makes them quite famous for designing unique roofs. And since their foldable quality does not change their structural strength and durability, they are crack and erosion resistant and can withstand harsh climatic conditions as well.
Zinc is a green environment material and is completely recyclable and maintains a low toxicity level. And as it has a low melting point the energy required to produce zinc is lesser too. If properly installed, zinc can last up to a century as well.
When comparing metal roofing to asphalt shingle types there are a few things you need to take into consideration such as price, durability, roofing style preference, overall maintenance, and lifespan of each roof type. While the initial material and installation cost of a metal roof type is higher than asphalt shingle roofs, their longevity is far superior lasting 40 to 80 years depending on metal type. Metal roofs last two to three times longer than a typical asphalt shingle roof, which sometimes only lasts 7 to 14 years.
Metal roofing can also increase the resale value of your home. Homeowners who invest in metal roofing get an average return on investment of Metal roofing can also lower your insurance rates and save you money because of its fire resistance, especially in states like Texas and California that are vulnerable to wildfires. Metal roofs boast a contemporary style, extensive warranties 30 to 50 years , and are very durable even in extreme elements such as heavy snow, hail, and even fire.
It is best to find metal roof installers near you to help with any roof installation projects you want to complete. It takes an advanced knowledge to properly install metal roofs and it is best left up to the roofing professionals in your area. Your roofing contractor will usually have this cost factor already integrated into your metal roofing installation estimate. From the factory, your metal roof products will be coated with either zinc galvanized or a mixture of aluminum and zinc galvalume or zincalume.
Of those options, galvalume is the longest lasting. All coatings are available in varying levels of thicknesses. Thicker coatings will absolutely last longer, but will also cost more initially. No matter which coating you select though, at some point, long term exposure to the elements will deteriorate the protective finish and you will need to recoat. A simple recoat with a polymer coating Kynar is the most popular will restore your metal roof to like-new conditions.
To wash, use simple soap and water — a hose or a pressure washer can be used, but avoid abrasive tools like wire brushes or steel wool that can scratch your roof. If you do scratch your roof, the scratched area can be wiped down with mineral spirits and touch up paint can be applied with a paintbrush. The long-life of your metal roof can be enhanced with proper maintenance.
Traditional roofing products contribute an estimated 20 billion pounds of waste to U. Reflective pigment technology comes in the form of a simple coating that enables metal roofs to reflect heat in the summer, while providing superior insulation in the winter.
Metal roof systems provides long-term energy savings, while decreasing your overall environmental impact. If you are unfamiliar with metal roofs, you may have concerns about the potential for rust, noise from rain and wind, and denting, but rest assured that modern engineering addresses these concerns.
Additionally, some believe that metal roofing will increase your likelihood of a lightning strike. While metal does conduct electricity, electricity is not drawn to it. In fact, because it is fire resistant, if your home is struck by lightening, your risk of fire is actually decreased with a metal roof.
