When you choose a new roof for your home, you might think that your main concern is keeping out precipitation. If that were the case, you could simply choose the least expensive material, a.k.a. asphalt shingles, that will still provide precipitation protection, and your job is done. However, there is much more that you need to cover. For example, you need to consider how your roof will shelter you from energy bills and replacement costs down the road. If you want long-lasting financial shelter, then you should look for a long-lasting energy efficient roofing material such as metal.
How Long Does Metal Roofing Last?
In order to understand the advantages of the longevity of metal roofing, you must first consider how long asphalt shingles will typically last—fifteen to twenty years. While this might seem like a good long time, consider that metal roofing can last for fifty years or more. What this means is that you will have to replace your asphalt shingles at least two times before you need to worry about replacing your metal roof even once. Because of the need to remove old shingles before installing the new, replacement costs are higher than installation costs, so it is easy to see that long-lasting metal roofing will help you to save money on replacement costs even if you must pay more initially to have metal roofing installed.
Asphalt shingles will absorb the sun's energy and convert it to heat before conducting that heat into your attic through your roof deck. You might think that attic insulation will prevent that heat from entering your home, but if your home never heated up during the day, then you would have no need to run your AC. The truth is that a hot roof is one key source of heat gain during the summer. By way of contrast, metal is naturally reflected and when treated with a white, emissive coating, these reflective properties are only enhanced. In fact, by deflecting the sun's energy before it enters your home a metal roof can reduce your cooling costs by up to 40%.
The above discussion illustrates at least a couple of the criteria that you should have in mind when you choose a new roof. By considering long-term costs as part of your decision, you can help to avoid costs down the road. While a metal roof will cost more initially, it will more than pay for itself over its service life, so the higher installation cost is worth it in the end.Share
