Out of all the big-ticket items in your home, your roof is one of the most important. It pretty much goes like this: Electrical box; Heating/cooling units; Water heater; Roof. Without the shingles on your roof, your electric bills would be through the, well, roof. Your shingles act as a barrier to keep the heat out in the summertime and keep the heat inside in the winter time. They also keep your home securely dry and help maintain normal, livable temperatures in your house.
Though there are different types of shingles, the majority of shingles are asphalt, and that is likely the style that you have. Even though most of us have asphalt shingles, many of them have different weights and life expectancies. The heavier your shingles of your roof are, they longer they should last. Notice we say “should.”
There is not really a shingle out there than can outlast the elements, especially here in the Atlanta area. The reason being is that we experience all types of weather. When people think about the Southeast, they assume it’s hot. While it may be hot right now, if you live here you know as well as anyone that the weather gets extremely, bone-chillingly cold in the winter. You’re aware of what it does to your skin, and you’re likely inside the majority of the time.
Imagine the toll the different extremes of weather have on your shingles. The cold and wet, the hot and wet, the hot and dry, the wind gusts, the hail, and all the different types of precipitation we receive annually.
So the weather, amongst a few other factors, has a bearing on how long your shingles will last. A 15-year shingle may only last 8 years, while a 25-year shingle could last about 20, and a 20-year variety might last 17. In a less harsh climate, these shingles may last a little longer.
Another factor that can influence how long your shingles last is the attic ventilation. The hotter your attic gets, the shorter the life of your asphalt shingles. A well-insulated attic can help your roof, as well. Though your HOA may not approve what color you choose, a lighter shingle will reflect and deter more heat than a black shingle.
As your shingles wear out, it will generally happen on one side of your house, as the side that is protected from the weather will see much less wear. Pitch and slope (steepness) can also play huge factors in how long your asphalt roof will last. A severely steep angle can exacerbate how wind and water affect the lifespan of your roof.
So the fact of the matter is that depending on the temperatures, the wind, precipitation, and other factors, your roof will likely last about 90% as long as you think it would. That doesn’t mean that there are not 25-year roofs out there that have lasted for 30 years. Asphalt shingles are still a relatively young science, and more advancements are being made every year. Hopefully, you’ll be in for lifetime shingles the next time you need a new roof.
