It's not uncommon for homes to have asphalt shingles for roofs. In fact, this is the most commonly used material for residential roofs, according to the Department of Human Ecology at Cornell University. The main reasons why this material is chosen over other options are its long life span and relatively cheap price tag. Before hiring a Kent roofing expert, it's important for homeowners to know just how much life they can expect out of asphalt roofing.

The average life span for any asphalt shingle ranges between 15 and 30 years. Although this may seem like a wide range, there are plenty of factors to consider. For example, heavier asphalt shingles tend to last longer than lighter ones. Other factors include the slope of the roof, the color of the shingles, climate and exposure to the sun. The coloring of the shingles matter because light-colored shingles absorb less heat, allowing them to last longer. The slope of the roof is important because it increases its ability to quickly shed water.

Weather plays a huge factor in how long asphalt shingles last. For example, the average life span of asphalt shingles is reduced to 12 to 14 years in climates that are hot. In areas that are cooler, asphalt shingles are much more likely to last 25 years or longer. In hot areas with lots of sunlight, it's hard to get a 20-year warranty on asphalt shingles because they aren't predicted to last that long.

The warranties that homeowners obtain on asphalt shingles are not limited to climate. The type of shingles used is the biggest determining factor as to the warranty that homeowners will receive. For example, the most commonly used type of asphalt shingle is the three-tab variety, which carries a warranty of roughly 15 to 20 years depending on the climate. However, laminated shingles carry a warranty of nearly 30 to 40 years depending on the climate. Since laminated shingles aren't used very often, they do little to affect the average life span of asphalt shingles as a whole.

Long before a homeowner's warranty runs out, it may be time to replace their asphalt shingles. The best way to tell if a shingle has run its life is to look for signs of deterioration. Homeowners should hire roofing experts to look for splitting, curling or cupping shingles. These are all signs that the shingles need to be replaced. If the shingles are only deteriorating in one area of a roof, homeowners might have the option of installing another layer of shingles over the deteriorating ones. However, this is just a quick fix because the remaining shingles will likely need to be replaced soon as well.
