If the roof on your home has finally given in, it might be time to consider replacing it with metal roofing. One of the many benefits of metal roofs is that they’re extremely lightweight, weighing between 100 – 150 pounds per square. Its durability can survive harsh weather conditions like storms, snow and torrential rain. Furthermore, metal roofing requires very minimal maintenance and is extremely energy efficient. 

In comparison to metal, there are more conventional materials used for roofing such as wood, tile and asphalt so it’s important to research the most suitable material for you, prior to purchasing. Fortunately, we’ve weighed up the pros and cons of metal roofing to help you make an informed decision before spending any money.   

Advantages of metal roofs

There are many advantages to metal roofs, making them one of the lightest, safest and strongest roofing options for homes. 

The benefits include: 

  • Safety: Metal roofs usually have a Class A fire rating and will not catch fire in the event of a wildfire or lightning strike. 
  • Longevity: Metal roofings has a shelf life of between 40 – 70 years, which is a lot longer than the 12 – 20 years that a conventional roofing material such as asphalt lasts. 
  • Easy Installation:  Metal roof installation has been made simple, the material usually comes in 12 to 36-inch panels or multiple sections. This makes it quick and easy to install.
  • Durability: Metal roofs can withstand corrosion, they won’t crack and some metal materials used can even resist impact. Certain metal roofs can even stay strong in winds of up to 140mph. 
  • Eco-friendly: Metal roofs are often made from around 25 – 95% recycled materials and can be recycled after use. 
  • Energy Efficient: Save energy in the long-term, metal roofs reflect solar heat which can on reduce cooling and A/C expenses by 10 – 25%. 

Disadvantages of metal roofs

Even though metal roofs come with many benefits, unfortunately, there still some drawbacks. 

The disadvantages are: 

  • Cost: Metal roofing can be a pretty costly endeavor and outside of your budget. The prices can range between $150 to $600 per 100 square ft. The big initial investment of metal roofing may be steep but due to the durability of the material, it may save you money on maintenance costs further down the line. 
  • Movement: Large panels of metal roofing may expand and contract with heat and cold. The panels may loosen if not attached correctly with the appropriate fasteners. 
  • Noise: At times when there’s heavy rain, metal roofs can be incredibly noisy. The noise can be reduced by applying structural barriers over plywood sheathing or insulation. 
  • Performance: It’s important to choose high-quality metals which can increase the cost. Low-grade metals may not be resistant to all weather conditions, less durable and thinner which could allow water to accumulate on the roof, leading to detrimental consequences. 
  • Accessibility: It can be difficult to walk across metal roofs in wet weather conditions or if moss and algae have bred on the surface. This can make it difficult to maintain the roof during fall and winter.

Metal Roofing Contractors

There is limited availability when it comes to finding a skilled professional for metal roof installation. It’s important to find an experienced metal roof contractor that knows exactly what they’re doing because it can make or break an installation. It’s not uncommon for the majority of issues with metal roofing to stem from an installation error and not the metal panels themselves. 

Where to find a metal roofing contractor: 

  • Ask for referrals from friends, family and neighbours 
  • See if you can find a certified contractor through the metal roof manufacturer
  • Get in touch with architects and building firms to see if they can help
  • Reach out to popular roofing organizations and associations
