How Metal Roofing Cuts Cooling Costs

Now that summer is drawing to a close you may look back over your utility bills for the season and be shocked at just how much you’ve had to spend just to keep your house cool.

Have you considered one of the contributing factors to this may be your roof? Whether your roof is old and damaged, or just made of inferior materials, it could be letting vast amounts of heat seep into your house throughout the summer months, meaning your air conditioner has had to work overtime in order to keep the temperature at the desired level.

If you are looking to save money on the cost of keeping your house cool then NEPA Roofing Pros recommend you look into investing in a new metal roof for your property.

Have a look at some of the ways a metal roof can cut the cost of cooling your home:

Upon Reflection

Traditional asphalt roofs act as conductors, retaining a great deal of heat throughout the day and then radiating that heat down into your home through your attic space. This heats your house up and means that your air conditioner will have to work that much harder to keep your house at the desired temperature.

If you install a metal roof on your home, however, the metal will reflect much of the heat and solar radiation that the asphalt absorbs and passes into your home. This is due to the lower thermal mass metal possesses, compared to asphalt. This means that your AC unit won’t have to be working overtime to keep your house cool, saving you money.

Add coating

If the base reflective properties of a metal roof aren’t enough for you, then simply apply one of many protective coatings available to it to further boost its reflective properties. Some of the most effective coatings allow your metal roof to reflect up to 90% of the solar radiation it is exposed to in a given day, which can help shave even more money on your energy bills.


If you want to save even more money on your energy bills, then when your metal roof is being installed ask for a pocket of air to be left between the underlayment of the house and the metal roof panel. This air pocket helps ventilate even more air out of the house during summer, keeping your house cool without you having to run the AC full blast.

Built to last

Although at first it may seem like a metal roof is too expensive for you to feel the benefit of any reduction in utility bills, a metal roof is actually a very worthwhile long term investment. This is because of the fact that metal roofs can last up to 4 times longer than asphalt shingle roofs, with very little maintenance required in that time. Given that for every year of its long lifespan a metal roof will be saving you money on your utility bills, both in summer and in winter, it represents a very sound investment for any homeowner.
