6 Factors That Affect the Lifespan of Asphalt Shingles

Asphalt shingles have been a popular choice for residential roofing for so many years now. Many homeowners prefer them because not only are they durable and beautiful, but they are also one of the most affordable options available today.

However, no matter how durable a roof material is, it is still susceptible to weathering. Weathered asphalt shingles are not the same as damaged shingles. The term ‘weathering’ is used as a way to describe how shingles are affected by constant exposure to different harsh elements over a period of time.

There are some factors that affect the lifespan of asphalt shingles.

  1. Roof Slope

Shingles on flat roofs tend to have shorter lifespans. In fact, roofing guidelines from roofing associations like the Asphalt Roofing Manufacturers’ Association and the National Roofing Contractors’ Association state that asphalt shingles shouldn’t be used for homes with roof slopes that are less than 3:12.

Design and Construction

There are properties with roof shapes that are more complex than usual. These often make venting more difficult. There are also instances when the design places a chimney or other obstructions in a roof valley and these result to interference of drainage and faster weathering.


Roof slopes that face south also have shorter lifespans. This is because they are more exposed to UV rays and subjected to higher thermal cycling.


Like other roof materials, the lifespan of asphalt roof shingles is also affected by the climate in your area. If you often experience harsh weather, then your roof will deteriorate faster than if you live in an area with a gentler climate.

  1. Quality of the Material

Not all roof shingles are created equal. All roofers will agree that one of the biggest factors that contribute to the lifespan of asphalt shingles is the quality of the material itself. Naturally, those of lower quality will show signs of weathering sooner than products with higher quality.

  1. Maintenance

Last but not least, proper maintenance also plays a big role in making sure that your asphalt roof lasts for as long as possible. Without regular cleaning, prompt repairs, and regular maintenance, your roof will deteriorate sooner rather than later.

All asphalt shingles get affected by weathering, but knowing what contributes to it and more importantly doing things that can help delay weathering can ensure that your roof lasts for many years.
