When it comes to selecting the type of metal roof you are having installed it is important to keep in mind the benefits that each material can provide. Four of the most popular forms of roofing are zinc, aluminum, steel and tin, but what can these metals provide for your home?

Zinc Roofing

Zinc provides a malleable and efficient roofing option, which can allow for creativity when creating your roofing pattern, however, zinc comes with a set of downfalls. If zinc is left without a coat of paint the material can occasionally turn a blue-green colour, and leave a chalk like a residue. It is also one of the softer metals, which can leave it susceptible to damage in the event of hail or other extreme weather.

Pros

Highly Durable: The durability aspect of zinc roofs makes it a preferred choice for homeowners looking for a good investment. It can last from 80 to 100 years and sometimes even longer.
High Resistance: This material is resistant to fire, repels insects and fungus and mildew. This means that you don’t have to worry about your house getting infested through the roof.
Patina Formation: The oxidation process of zinc, also known as patina, leads to the material forming a protective layer on it. This helps it resist dust and weathering and also reform itself from blemishes caused due to natural causes.
Aesthetically Appealing: Zinc roofs are appealing because they naturally change colour from classic dark grey to light grey and overall give a very sophisticated finishing to the exterior of your house.
Low Maintenance: If the zinc roof is installed properly, you do not have to call the contractors multiple times in its lifecycle to maintain the system.
Eco-Friendly: Zinc roofs are recyclable and can be used again for your roofing needs. 

Cons

Expensive: Zinc roofing may overall turn out as an expensive form of metal roofing as it ranges from $10 to $20 per square foot including materials and installation.
Unpredictable Patina Formation:  The oxidation of zinc is a natural process that also adds to its aesthetics. But this process is unpredictable as it can happen within 2 years or may take 20 or even 30 years.
Problematic if Installed Poorly: If zinc panels and the underlayment has gaps, corrosion and leaks can occur. This may also lead to mold. 

Steel Roofing

Steel is a metal which can provide an increase in structural strength to both aluminum and zinc, but it often requires a coating in order to protect against rust and corrosion. Steel is efficient in terms of retaining heat, which makes it an ideal metal for colder climates. It is one of the most recycled materials on the planet, meaning it can be made in an efficient and environmentally friendly manner.

Pros

Long-Lasting: The durability of steel roofs makes it the most popular choice in the market today. A superior quality roof made from this material can last for over 100 years.
All-Season Strength: These roofs can withstand extreme weather conditions without weathering, curling or breaking apart. Since it is non-combustible and can withstand strong winds, snow, hail and rains, it gives you a year-round protection. 
Availability of A Variety of Designs: Today, there are a variety of designs available in the market. You can choose from a variety of styles, colours and seam designs to make the whole exterior of your house look very appealing.
Low Maintenance: You do not have to call in for maintenance of your steel roof after every season. Since these roofs are resistant to curling or weathering, they can go on for years with little to no maintenance.
Energy-Efficient: The reflective qualities of these roofs keep the temperature within your house desirable. There are many coatings for these roofs that make them energy efficient.

Cons

Expensive: Though the overall cost is cheaper than zinc, steel is also an expensive option. Usually, installing these roofs may cause anywhere between $10 to $15 per square foot.
Noisy: If you live in an area with heavy rains, hailstorms or acorns, the metal roof made of steel may be too noisy.
Expansion and Contraction: Steel roofs expand and contract over time and if the wrong fastener is used, it may lead to leaks. Fixing this may be of an additional cost.

Tin Roofing

Tin has declined in popularity as a method of roofing due to the increased usage of, particularly aluminum, and steel. It lacks the durability of other metals and has thus become one of the more rare and uncommon sights in the larger picture of metal roofing selection.

Pros

Good for Diy Projects: If you are building a tree-house or a cabin in your garden, tin roofs can be considered as they are easy to install.
Fairly durable: By virtue of being a metallic roof, these roofs are durable. However, there are more durable metal roofings available in the market.

Cons

Not Easily Available: Tin roofs may have been replaced by stronger and more functional materials which is why they are not easily available in the market today.
Do Not Consist of Tin: When builders refer to tin roofing, they refer to another galvanized metal roofing version of steel which may not necessarily consist of tin but may only give a tin-like look.
Not so Popular: For homemakers who want their roofs to increase the value of their house, tin roofs are often rejected for another material.

Aluminium Roofing

Aluminum is a lightweight and malleable material with which to make a creative roofing design. Aluminum is highly resilient and resistant to corrosion and is often recommended for more coastal residents. Aluminum is protected from the damages of rust, and does not require a protective coating in order to prevent it.

Pros

Durable: Just like steel and zinc roofs, aluminium roofing is also quite durable. It is resistant to corrosion which makes it long-lasting.
Good for Coastal Homes: If you live near the sea or in high humidity weather, this type of roofing is the best for you. Its resistance to corrosion and active adaptation to the weather makes it perfect for coastal regions.
Lightweight: As compared to steel and even copper, these roofing has more lightweight panels and may not be too heavy to be reconstructed on homes with older foundations.

Cons

Expensive: Despite the benefits it provides, some might consider this type of metal roofing system to be more expensive. The average cost of this roof comes up to $9 to $13 per square foot.
Requires Additional Coating: Unlike Zinc, this roof may require an additional coating to protect and painting to look more aesthetically appealing.
Not Suitable for Windy Areas: Because it is light weight, aluminium may not be the right choice when it comes to homes located in windy areas or areas prone to storms.
