What Are the Advantages and Disadvantages of Metal Roofs?

Choosing a new roof for your home can be a bit overwhelming, especially when you consider there are many different types of roofs to choose from. When choosing a roof, you’ll want to take into account more than just the price. After all, you’ll want to make sure the roof you install will do a good job protecting your home against the elements and will last for years to come. One type of roof you should take into consideration is metal roofing. The following are some of the pros and cons of metal roofing.

Metal roofs are a common choice, both in new construction and when an aging roof needs to be replaced. Metal roofing products can be made from a variety of metals, including galvanised steel, copper, aluminium, or tin, and they can use several different installation systems. There are a great many advantages to a metal roof, but also a few disadvantages to consider.

Metal roofing is a popular option for new roofs, especially due to its reputation for longevity and attractive curb appeal. Metal roofing can last far longer than asphalt shingles, so it is an option that many Toms River roofing customers may wish to consider. However, there are some potential disadvantages to metal roofing which the homeowner should consider as well. A consultation with your professional roofing contractor will help you to learn which roofing material will be the best option for the roof of your home.

Metal roofing provides many advantages, including the ability to withstand nearly any type of weather condition while keeping the home cozy and dry. Rain easily drains quickly from a metal roof, and snow can melt and slide off a roof very efficiently as well. Metal roofing can be obtained in various levels of quality, including roofing with fire resistance and the ability to withstand a hail storm without damage. Metal roofing comes in many different colours and finishes, including the look of natural cedar shakes or stone. It is a very attractive, roofing option for many homeowners. It can be expensive, but the durability and longevity it provides easily justify the additional cost. Take a look at our range of roof repairs Melbourne.

Advantages & Disadvantages of Using Metal Roofing

Metal roofing is an alternative to traditional asphalt roofing that’s usually composed of large sheets, though varieties are available that mimic the look of standard asphalt shingles. Materials that may be used for metal roofing include zinc, tin, steel, copper, aluminium, and hybrid metal mixtures, all of which are finished with special coatings to reflect heat, prevent rust and seal the material against moisture damage.

How To Keep Your Roof In Perfect Condition

Metal Roofing Advantages

There are some notable points why metal roofing sheets stand out from other roofing materials. These include but not limited to:

Durability & Longevity

Once properly installed, a metal roof is capable of lasting as long as the house is standing because metal roofing doesn’t rot or crack, neither does it warp or curl. The shingles or panels don’t break or split, nor can they burn, and the design doesn’t peel off for ages.

Metal roofing seals off the water, capable of surviving high winds, and it can shed snow and thawing quickly. Metal also can resist fire, insects, mildew and wane. Most roofing companies in Huntington Station selling metal sheets provide warranties, which vary from company to company, but the minimum duration of warranty given by most roofing companies in Huntington Station to back up their products ranges from 20 to 50 years. Metal roof sheets that come with paint designs usually have limited warranties lasting 30 years.

Easy Installation

Metal roofs are fast and easy to install, most especially if panels are involved. Compare to the conventional roof like tiles, metal roof sheets are seven times lighter in weight, which makes them extremely suitable for houses that appear fragile.

In the area of panels, a lot of the metal roofing sheets available today come in 12 to 36 inch wide panels or what is known as “multiple shingle sections.” These are very easy for an experienced roofing contractor to install in no time.

If you have some section of your room taken off and the weather forecast says there is an approaching storm, cutting back on the reinstallation process by a day or day may prove extremely critical, and because these metal sheets are lightweight, you can save on high-level engineering while reinstalling the supporting structure.

Heat Management

Metal roof sheets minimise the heat gained during the midday by reflecting the radiant heat coming from the sun, which means you are capable of saving the amount of energy required for air conditioning during the day. Even though metal roofs are low in insulation-R-value, a lot of metal roofing systems make use of a dead-air-space that exists between the roof deck and the metal to increase the effectiveness of the energy.

Ability to Resist Fire

Metal roofs are given Grade A fire rating because of their non-combustible nature. A major factor that sums up the classification of any roof material is the component beneath the surface that could flare up in intense heat. A lot of other metal roofs installed across combustible materials like wood shingles are rated very low, with a Class C rating.

Low in Maintenance Cost

You may never have to spend a dime in maintaining your rooftop overlaid with metal roof sheets. And even if you will have cause to carry out some minor maintenance, it is either to brush off leave sticks or to repaint if you had initially painted the roof’s original finishing.

Better Resale Value

Using metal sheets means that there would be no future dilapidating factor that is required to be rebuilt for the roof, as a potential buyer knows he or she will not have to think about replacing the roof throughout the house lifetime. Thus, the price value of the home will relatively be maintained in the event of a resale.

An Added Glamour

The wide range of different styles that are available provides a chance to select the option that will perfectly fit in and complement the overall type and style of the home.

Metal Roofing Disadvantages


The biggest drawback to metal roofs is the initial cost—about $15 to $60 per square foot or two to three times as expensive as traditional materials. If you plan on living in the home for a long time, you’ll likely see savings in the long run, but if you plan on only staying in the home a few years, you’ll likely come out in the red.


To some, rain on a metal roof is a soothing tap-tap-tap that puts their mind at ease and helps them fall asleep. For others, it’s an incessant annoyance. You can add insulation to mitigate the issue, but ultimately if you know you’re the type of person who could be driven up the wall by those types of sounds, you should give metal roofs a scrupulous look.

Denting and other damage

Though metal roofs are guaranteed to last decades, they can still take damage from branches, hail or any other falling object. How likely your roof is to dent depends on the material you buy. Some metal roofs’ paint is also prone to chipping and fading. Touching that up requires delicate movement as it’s easy to cause more damage walking on top of the roof.


Steel Tile RoofStyle options are limited to steel panels. Asphalt shingles are made to resemble wood shakes or slate. Most steel roofs, on the other hand, are made with 2 ft or 3 ft wide steel panels that are either smooth with upright seams or corrugated with wlittle ridges. Some manufacturers offer metal shingles, but they are frightfully more expensive, which brings us to the next disadvantage.

Natural hazards

Some might assume metal roofs may attract more lightening, and while that’s generally not the case, it is a good idea to have your roof grounded. The greater concern is fire. Though the metal roof shields your home well from fires on the outside of your home, a fire that starts inside the house can be a problem. Firefighters may need to cut through the roof to get to the fire and an access point complicated by a metal roof.

Types of Metal Roofing Materials

Believe it or not, metal roofing has come into its own and is more in demand than you would think. With its rise in popularity, there is a myriad of roofing material choices available today. Most metal roofing manufacturers offer various metals as well as different metal roof styles and types. There are pros and cons with each metal, and here is an overview of five (5) different ones and what they have to offer. Check out our roof replacement Melbourne services.


There is no doubt that copper is a striking but expensive metal. It has its appeal for those who can afford it, but an entire copper roof is a rarity, and any use of it wwwwwis normally for accent purposes. Copper is a long-lasting material as well and is often seen on historical structures that are well over a hundred years old. It is also seen on historical structures as well as steeples, domes and ceilings. In addition, copper is also attractive over different parts of a home or building, such as bay windows or dormers. Copper also works well as flashing when it’s combined with other types of metal roofs, though it doesn’t do well with aluminium and steel. Any close contact that copper has with a differing metal triggers an electrochemical process (galvanic action)that causes it to experience corrosion.

Copper does go through a transformation period that extends anywhere from eight to fifteen years. It takes on a patina sheen that acts as a barrier that adds increased durability to copper. Various types of copper in the form of shingles and other related roofing materials are available and can be found in the patina form or in a form where the patina comes on more slowly.


Aluminium is an excellent choice in a metal roofing material for any area of the country. It’s particularly beneficial for homes in coastal regions, as it’s resistant to rust and salt corrosion. Besides being corrosion-resistant, aluminium is lightweight and energy-efficient, plus it’s available in different contours. It can resemble shingles, shakes, tiles, slate and standing seam. Aluminium roofing also comes in a number of colours, as it can be painted.

One problem with painted aluminium is its loss of lustre over time, which diminishes the attractiveness of the metal. Another drawback with aluminium roofing is its cost. Aluminium can be expensive and falls between copper and steel as far as price is concerned. It has a thinner cut than steel, so panels are not as thick and can be subject to the stress of severe wind and hurricanes.


Zinc is a good roofing material choice in spite of its not so familiar face in the marketplace. Though not as well known as a roofing material, zinc has made recent headway due to its eco-friendly nature. It’s recyclable and has a melting point that is lower than standard metals. Zinc requires a limited amount of energy in its production, and it has pliable qualities that allow for both commercial and residential applications.

An issue with this metal is the chalking effect, which happens when zinc ages. When zinc is not painted, it will appear almost blue-grey in colour. As zinc is a soft metal, it will be vulnerable to wind storms, hail or debris. It is much like aluminium in those respects.


Steel is the hardest of all metals, and it is less expensive in comparison to copper, aluminium, and zinc. Steel has shown great strides as a roofing material, and the latest improvements in paint systems have caused steel roofing to rank even higher. These newer paint processes allow for the imitation of the patina and lustre that are found with copper and zinc, which gives the steel a boost in the market.

There are two types of steel, which include:

Galvanized Steel

Galvanised steel is the standard form for metal roofing material. It is made from carbon/iron steel along with a zinc coating that is metallic based. There is considerable protection with this type of coating as zinc is able to protect and repair through time and extend the life of the steel. Galvanised steel structure and maintenance relies on the quality of zinc used. There are lesser grades available, but they are not suitable for home roofing. It’s also not recommended for those who live in coastal areas as the salt air is highly corrosive and will affect the life of galvanised steel.

Galvalume Steel

Galvalume steel is also made from carbon/iron steel and has a coating of aluminium and zinc. This combination creates an enhanced aluminium. As aluminium resists and protects against corrosion, galvalume steel is made more durable and resistant to corrosion. Galvalume steel will, however, lose its self-protection over time and is susceptible to tiny cracks, particularly with its thinner zinc coating. Galvalume is found to be best for commercial roofing jobs as it provides smoother and more lustrous surface protection, but it can be subject to scratches and cuts.


A tin roof is comparable to and interchangeable with metal, galvanised steel, and steel roofing. It is a favourite choice of many homeowners and builders, in and outside of America. Tin is actually rather rare and not typically used for roofing. Like copper and zinc, tin is considered an element and was initially used in canning. It was later flattened out by do-it-yourself roofing enthusiasts in rural areas. They used it in this flattened form to make their own shingles when other materials were unavailable. Tin went by the wayside when aluminium was developed for container use, plus tin was no longer in use as a homemade building product.

Any mention of a tin roof today actually means a galvanised steel or aluminium roofing material. Tin has gone the way of the “tin can” and flattened roofs from several centuries ago, but the word itself still seems to have implication with do-it-yourself roofing. Any use of tin today is limited to scientific and technological aspects, so it is no longer in general use as a building or roofing material.

Metal roofing can be costly, and it has its positives and negatives. Once you weigh the advantages of any of them along with the costs, you should be better able to make a choice that fits your budget and needs. You just need to find a good roofer experienced in metal roofing installation as well as know your logistics as to where the roof will be installed and what kind of forces and tensions your structure will be able to endure.
