The average cost of installing metal shingles on a residential roof is between $8 and $12 per square meter. In this guide we explain all the important factors that determine the total cost of metal shingles, as well as the pros and cons. We will also cover the material costs of the various metal tile options and make some comparisons with other popular roofing materials.
Of the three main metal roofing options (the others are standing seam at the top and corrugated and ribbed metal panels at the bottom), perhaps the most important, from a cost perspective, is the fact that metal shingles and blowboard are in the middle.
Understanding your options
At first glance, metal shingles seem insignificant or perhaps too risky in an area where they are clearly out of the norm (i.e. all your neighbours have asphalt shingle roofs).
However, when examining residential metal shingle styles and options, you may be surprised to see images that look a lot like asphalt shingles.
Why would I do that? Because the reality of metal shingles is that it is in fact a metal shingles designed to imitate almost all other possible roofing styles; slate shingles, ceramic shingles, asphalt shingles, cedar shingles and, for example, redwood shingles are all materials that can imitate metal shingles.
From the sidewalk it would be difficult to distinguish the metal material from its conventional counterparts. This is how the metal tile industry diversified.
In addition, the metal itself can have an attractive appearance, as in the case of copper, zinc, lacquered aluminium and steel tiles. The days when metal shingles only had a silver-grey, metal look are over.
Fact: There are actually two main types of metal roof tiles, or metal roof tiles: galvanized steel covered with a protective metal coating, often with a factory Kynar 500 paint, and the second type, covered with stone granules, called stone covered steel roof tiles.
It is the stone-covered variety that opens the door to metal shingles, which look almost identical to asphalt tiles because they are covered with granulate just like asphalt tiles. Metal tiles are also available in aluminium, zinc and copper.
Not only the color but also the texture of the metal shingles makes it possible to obtain a wide variety of product options.
With the optional texture, slate, wood and ceramics are all possible options for metal roofs.
Then there is the shape, which varies slightly depending on the manufacturer, but is usually rectangular or diamond-shaped.
How it’s installed: The installation of metal shingles is generally based on a locking system, which allows for faster installation and the possibility of hiding the fasteners.
Some manufacturers still have panels of 4 tiles (per panel) glued to the roofing.
The panels are generally one metre long and are often installed on existing roofs (i.e. metal shingles can be installed over asphalt shingles).
Did you know that? Standing seam shingles are currently the second most popular form of metal roofing for homes after standing seam shingles.
Another consideration for shingle options is the material or type of metal itself, but we will return to this in the next section.
Material: On average, metal shingles cost between $3.50 and $5.50 per square meter for materials, including finishing, depending on the profile and supplier. It’s just the cost of the materials and metal parts for trimming and flashing. – That’s two to three times the price of materials for asphalt shingles.
Total cost of installation : When the cost of professional installation is added, the total cost is generally in the range listed at the beginning of this article, $ 8 to $ 12 per square foot of installed metal shingles. This is about twice as expensive as asphalt belts. However, the costs are much higher than those of asphalt belts, as discussed below under benefits.
The caveat regarding the price range is that this applies to the two most popular materials for metal shingles, aluminium and steel.
When it comes to zinc or copper, the costs go up considerably. For copper the cost of the material is about $12 to $16 per square foot and for zinc the cost is about $6 to $8 per square foot.
Materials and finishes for aluminium and steel shingles and tiles range from $3 to $5 per square foot.
According to RoofingCalc.com, a roof of 1,600 square meters of steel costs between $12,000 and $18,000 according to the cost calculator.
There are a number of factors, even for this specific material, that can affect the price range; you can take the location – like a different zip code on the RoofingCalc.com calculator – with you and see the prices change.
Using professional contractors will influence the prices you get, as will whether or not you tear off and throw away your existing roof, which is usually not the case with metal shingles, but it can be.
In general, metal shingles require what is called a breathable layer or underlayment, which is located directly beneath the metal and acts as a water barrier, although this only adds about $25 per square meter (equivalent to 100 square meters) to the cost of the materials.
The larger the surface area of your roof, the less material you have to pay per square meter.
Technically, G 90 galvanised steel, a common material for metal shingles, is cheaper than aluminium, but by the time metal shingles are sold to the end user, they will remain the same.
Aluminium and steel will most likely be repainted. It is important that you choose Kynar 500 or Hylar 5000 factory-manufactured paints because they offer the best protection and usually have a guarantee of at least 20-30 years.
Colors are normally unlimited, but wholesalers tend to offer a dozen popular options that most homeowners choose. The texture adds a completely different layer to the available options.
Steel, however, needs an extra coating in order to be easy to paint. This layer is (usually) called galvanized. It is a metal primer that significantly protects the base material of the steel. Without it, steel is susceptible to corrosion, commonly known as rust.
Aluminium can also corrode, but is subject to scale or a whitish film when the protective (painted) coating has faded.
The steel coating is 100% zinc (galvanized steel), one of the most durable metals. Some metal sheets can also be coated with a mixture of zinc and aluminium. All zinc coatings are G-90 galvanised steel and the combination coating is Galvalume.
Zinc and copper tiles do not require any special coating or paint as they are non-aggressive metals. In fact, these materials deserve their own article.

Calculation of return on investment and depreciation
As you can imagine, metal and stone roofs last longer than any other type of roof. That’s a big advantage, and it makes them an excellent investment.
Once a house has gone through three life cycles of asphalt stone quality, it may be necessary to replace a metal roof for the first time.
While the initial cost of metal is much higher than that of asphalt shingles, the long-term cost of metal is actually lower. Again, the benefits section will help you.
The return on investment (or ROI) of metal roofing materials is higher than that of all other roofing materials. Most manufacturers of metal roofing products, especially for roof tile products, offer a 50 year guarantee that is uncontrollable and fully transferable.
Asphalt shingles have the chance to last half as long, and their guarantee is usually printed on them.
Cedarwood swing roofs certainly have a natural beauty, but metal swing roofs can look very similar and will easily survive their wooden counterparts.
Metal roofs are becoming more and more popular, which only increases their resale value. The national average is about 86% return on what you contribute and what you can expect at the time of sale. This figure varies by region, with the East tending to have the highest return on investment in metal roofing materials.
Style Factor A classic colonial or brick house would probably benefit more from a metal roof tile house because it retains a traditional appearance while offering all the advantages of a metal roof.
Pay attention: The asterisk after the following points applies only to metal shingles. Most advantages and disadvantages of all types of metal roofs.
- Can be installed on an existing roof*.
- Coating of special material resistant to dirt and environmental ageing
- A very wide range of variations in shape, texture and colour*.
- Power factor 1 – lasts an average of 100 years.
- Force factor 2 – can withstand winds of 110 mph.
- Resistance factor 3 – hail resistant (check the manufacturer’s specifications for exact impact resistance).
- An excellent return on investment
- Mostly made from recycled materials, so environmentally friendly and 100% recyclable.
- It doesn’t burn, isn’t eaten by insects and doesn’t mould.
- The retrofitting of solar panels can be costly and can expose the weak points of the metal shingles*.
- Significantly higher installation costs than asphalt shingles.
- maybe a bump from a major hailstorm or from recklessly entering it.
- The material lasts longer than the coating, so applying a new coating is part of the maintenance (but usually at least 30 years after installation).
- Repairing certain types of shingles can be difficult and/or costly*.
