Metal roofs are incredibly durable and can withstand harsh weather conditions better than other types of roofing materials. They are resistant to wind, rain, snow, and hail. They are also resistant to fire, making them a safe choice for buildings in areas prone to wildfires.
When properly installed and maintained, a metal roof can last for 40 to 70 years, depending on the type of metal used. This is significantly longer than the lifespan of traditional asphalt roofs, which typically last for 12 to 20 years.
Energy Efficiency
Metal roofs are highly energy efficient. They reflect solar radiant heat, which can reduce cooling costs by 10% to 25%. This can be particularly beneficial in areas with hot climates, where cooling costs can be a significant portion of a household’s energy bill.
Eco-Friendliness
Metal roofs are also eco-friendly. They are typically made from 30% to 60% recycled metal, and at the end of their life, they are 100% recyclable. In contrast, most other types of roofing materials end up in landfills at the end of their life.
Disadvantages of Metal Roofing
Despite the many advantages of metal roofing, there are also some disadvantages that you should be aware of.
Cost
The initial cost of a metal roof is higher than that of other types of roofing materials. However, it’s important to consider the long-term value that a metal roof offers. Given its long lifespan and durability, a metal roof can be a cost-effective choice in the long run.

While steel roofing is heavier than other types of metal roofing, it is also sturdier and can withstand extreme weather conditions better. It is also more affordable than other types of metal roofing.
Steel roofing can be divided into three types: galvanized steel, galvalume steel, and weathering steel. Each type has its own unique features and advantages.
Galvanized steel is steel coated with a layer of zinc, which provides protection against corrosion and rust. Galvalume steel is steel coated with an alloy of zinc and aluminium, which offers even greater resistance to corrosion. Weathering steel, also known as corten steel, develops a protective rust patina over time, which protects the steel from further corrosion.
Aluminium Roofing
Aluminium is another popular material for metal roofing. It is lightweight, durable, and highly resistant to corrosion. It is also more expensive than steel, but it offers superior performance in coastal areas where salt spray is common.
