Is Metal Roofing Energy Efficient?

If you’re looking to reduce utility costs, it is critical to have an energy-efficient roof on your home. That’s where metal roofing comes in. You’ve probably seen metal roofs installed in your area and have heard about their advantages, including energy efficiency. If you’re asking yourself if this claim is accurate or if it’s just an effort to explain the higher initial investment, here’s your answer: metal roofing is the most energy-efficient roof!


How are metal roofs energy-efficient?

The simplest reason for the effectiveness of metal roofs is their ability to bounce the sun’s warmth away from the property. While other roof materials, such as shingles, absorb most of this heat and increase the interior temperature, metal roofs act like giant mirrors and reflect the heat, resulting in a minimal increase in interior temperature.

The level of energy efficiency of metal roofs will be affected by how they are installed. Research shows that metal roofs fastened with a batten or counter-batten system underneath to enhance airflow have a 45% decrease in heat flow. In addition, ridge venting, which comes standard with most Toronto steel roofing systems, allows for higher hot air removal than conventional roof vents. This allows warm air to escape from your roof’s attic through the ridge line, preventing excessive amounts of condensation. On the other hand, asphalt shingle roofs retain the sun’s heat and absorb it into the home. At times, they can increase interior temperatures by as much as 25 degrees Celsius.


The Price
In general, metal roofs cost more than shingles. While the initial cost may seem higher, once the metal roof is professionally installed, it offers many benefits that will make your investment worth every dollar and more.


The Savings
With a metal roof in place, you will no longer need to run the air conditioning constantly during the hot summer months. This will save you hundreds of dollars on your utility bills. Still, it will take time before you start reaping the benefits of these savings, so be patient.


The Longevity
Metal roofs have a lifespan of about 60 years. It’s this longevity that allows you to take advantage of the savings from lower utility bills. They also require little maintenance and you will likely never have to incur the cost of installing a new roof again, allowing you to recoup your initial investment.


It’s a great thing to get great benefits while preserving the environment. Metal roofing will allow you to do just that, as it can be recycled once you no longer need it and does not contribute to landfills.
