If you want stylish, eco-friendly roofing that stands up to snow and ice better than the other materials, metal is a great option. It’s ideal if you plan to live in your current home “forever” or want a roof with excellent resale value.
Metal roofing materials will last about 30–50 years. Made of steel, copper, zinc alloy, or aluminum, metal roofs are slightly more expensive than their asphalt and wood counterparts. That said, they are significantly more durable.
Metal roofs are impact resistant and will serve you well in inclement weather (plus, the sound of rain on a metal roof is wonderful). Also, they need a lot less maintenance than most roofing materials. They are very energy efficient—while asphalt shingles tend to hover around the outside temperature (whether high or low), metal roofs act as a natural insulator. This keeps your home cooler during warm weather and warmer during cold weather.
Finally, their recyclability is unparalleled. Not only are most metal roofs created from recycled materials, but many are also 100% recyclable themselves.
Your great-grandfather’s home or barn might well have been roofed in metal, and some of those 100-year old roofs are still going strong.
Metal has enjoyed a recent resurgence led by demand for durability, eco-friendly roofing, and the introduction of new styles.
Metal roofing is still manufactured in rolls, but most are rigid sheet roofing with vertical-seam panels and modular press-formed panels that can be painted or coated with granules.
The manufacturing processes allow for a variety of appearance options including the traditional metal roof style and roofing made to look like shingles, shakes, and tiles. The most common metals used are aluminum, lightweight steel, and zinc. Copper metal roofs are a beautiful but costly specialty!
What’s good about a metal roof?
New styles can mimic shingles, shakes, slate, and tile, and dozens of colors are available
Metal is a 50 to 100-year roofing material with warranties of 30-50 years
Metal reflects solar radiant heat, so can keep your home cooler and control energy costs in hot weather when compared with asphalt
Many metal roofing profiles have a Class A fire rating
Some styles of metal such as corrugated and ribbed panels that are common to barn roofs can be installed quickly and on a budget
Metal sheds rain and snow better than most other roof materials, which helps prevent ice dams during extreme cold
Recycled materials are used in most metal roofs, and the roofing panels are 100% recyclable at the end of their service life
Today’s metal roofing products are surprisingly lightweight yet offer outstanding resistance to impact
Metal roofs look great on wood-sided homes, cabins, cottages, and those with simple, rustic design
Many residential metal roofs such as metal shingles, standing seam, and stone-coated steel tiles are designed to meet the most stringent building codes.
metal alternatives such as zinc, aluminium, and copper are most frequently used a cheaper alternative are the materials used for flat
roofs: VPC, EPDM, or bitumen. A disadvantage here is the outlook rather new materials are the slates and roof tiles. However, In this case, one has to pay more attention to the waterproofness of the roof
Metal roofing comes in vertical panels or shingles resembling slate, tile, and shake – and lasts about 60 years. Metal excels at sliding off heavy snow and rain, won’t burn, and resists high winds. It is lightweight and can be installed over existing roofs. However, metal can be noisy during rainstorms and may dent from hail. Average costs range between £5 and £12 per square foot, depending on the type and style of metal – which is more than asphalt but less than concrete tiles. Corrosion also varies by material.
Metal roofs are very long-lived and are fully recyclable when they finally do wear out. But installation requires special skills and not every roofing company is prepared to install a standing seam metal roof.
For homeowners who do not like the look of standing seam metal roofs but want the advantages of metal, there are steel or aluminum shingles or shakes now available. Made from stamped metal and finished with either a high-quality baked-on coating or mineral granules, metal shingles can be fabricated to look very much like traditional asphalt shingles, wooden shakes, or even slate or clay tiles. They are an excellent choice where appearance is a critical concern…
Metal tile sheets: sheets of steel or aluminium with the look of roof tiles. The system is easily placed and it is not as heavy as roofing with real tiles;
Zinc slates: they have the same look as a natural slate, although they are a little bit bigger;
Zinc, aluminium or copper strips: as time goes by, a patina will be formed. This gives protection (longer lifespan) and a nice colour to the roof.
Metal roofing systems metal roofs have been around for many years and have long been used in a commercial and industrial setting. However, this material is becoming increasingly viable as a roofing option for homeowners. Metal roofing systems are low maintenance, lightweight, very versatile in style and design, and are one of the most environmentally friendly roofing materials available. They can be made in any colour needed and can also be designed in a multitude of styles including shingles, panels, sheets, and even tiles. Metal roofing may cost a bit more initially to install, but it lasts a long time, resists wear and tear from weather, and can greatly increase the value and appeal of your home in the long run. However, installation can be tricky when large panels and sheets are used, and not every roofing contractor has experience with metal roofing system installations.
Before you choose metal, know its potential disadvantages:
The cost of metal roofing is higher (copper is in the league of its own as the most expensive option) than asphalt shingles and wood roofing, but that is usually offset by its durability and longevity
Without an attic space or a proper substrate such as solid sheathing (boards or plywood), metal roofs installed over open framing and directly over living space can be noisier than other materials when the rain hits it
The material can dent when hit with a heavy object, and replacing metal panels is costlier than replacing asphalt, wood, or tiles, although many metal roofing styles are rated to withstand large hail
While protecting the home from windblown sparks and cinders, in some situations metal roofing can make it more difficult for firefighters from breaking through the roof to pour water on an interior fire
