What are the Advantages of a Metal Roof?

There are many metal roof benefits that make it an excellent choice for all types of houses. These benefits range from weather resistance to aesthetic appeal to durability to the fact that it is environmentally friendly, which will be expanded upon below:

  • Fire and Weather Resistance — Metals roofs are considered non-combustible and the most resistant to fire with a Class A fire rating. They are also able to withstand all kinds of weather conditions including strong winds, rain, snow, and hail. This ensures that you will be protected from the elements at all times.
  • Wide Range of Colours and Styles — With a variety of materials, styles, and colours to choose from, metal roofing can work with any type of architecture and match whatever your aesthetic preferences may be to add to the curb appeal of your home.
  • Longevity and Durability — In terms of longevity, the typical lifespan of a metal roof is between 40 to 80 years, which is much more lengthy than that of standard asphalt shingle roofs. In terms of durability, it is strong, highly resilient, and will not easily crack. The strength of a metal roof is seen in its thickness, measured by gauges. The lower the gauge number of your metal roof, the thicker and stronger the steel. Due to how sturdy it is, it has the added bonus of requiring minimal maintenance.
  • Energy Efficient and Eco-Friendly — Did you know that a metal roof can save you around 40% on energy costs? It has the ability to both absorb the sun’s heat, keeping you warm in the winter, and reflect solar radiation, keeping you cool in the summer, which means that your heating and air conditioning units don’t have to work as hard. This saves you money in the long run. Metal roofs are also made from as little as 35% to as high as 95% recycled material and will be 100% recyclable at the end of its lifespan, demonstrating how eco-friendly it is.

What are the Disadvantages of a Metal Roof?

There are also some disadvantages to metal roofing that you should be aware of and carefully consider before moving forward, including cost, noisiness, and the possibility of water damage. These disadvantages are expanded upon below:

  • Installation and Cost — Installing a metal roof should not be a DIY project as the installation process is quite complex and dangerous without any previous experience. Therefore, it should only be done by professionals which will add to the cost. When it comes to cost, metal roofing is more expensive than other roofing options, though the potential savings in energy bills and maintenance fees can balance this out over time.
  • Noisiness — Metal roofs can be noisy during storms. While they are weather and impact resistant, you’ll still be able to hear rain or hail falling on them. As well, they are known to expand and contract in different temperatures which could result in additional noise when this occurs, especially when it cools down at night. However, a layer of soundproofing insulation can be installed with the roof to counteract these possible sounds.
  • Corrosion and Water Damage — Though metal roofing is highly weather resistant, it can also trap water vapour and rising moisture that could eventually cause damage and rot in the trusses and decking, but making sure to install a proper ventilation system will help mitigate this.

FAQs

The downside of metal roofing is that it’s more expensive than other roofing options and difficult to install, meaning you cannot install it yourself and will need to get professional help. In the grand scheme of things, though, the benefits of metal roofing greatly outweigh the downsides.

The biggest issues with metal roofs are the possibilities of noise, caused by storms or the expanding and contracting of the roof in different temperatures, and water damage, caused by the retention of water vapour. However, installing a layer of soundproofing insulation and a proper ventilation system will help mitigate these issues.

First off, while there is a myth that metal roofs attract lightning, this is not actually the case; in fact, there’s no reason to believe that metal roofs are any more likely to get struck by lightning than traditional asphalt roofs. Unlike asphalt roofs, though, because metal is such a conductive material, it’s great at grounding. This means that if lightning does strike a metal roof, it will quickly transfer the heat and energy away from your home and into the ground, which will reduce any chance of damage.

Like any other type of roof, there is always the possibility of leaks over time as your roof gets older, but due to the metal roof advantages of durability and longevity, this possibility is lessened. Indeed, because of how durable a metal roof is, it’s highly unlikely that it will develop leaks at all.
