Factors That Affect the Age of Your Asphalt Shingle Roof
Asphalt shingles are one of the most popular roofing materials today. They offer great protection against the weather at a reasonable price, making them a roofing product of choice by many homeowners across the country. An asphalt shingle roof has a decent lifespan of 20 to 30 years, depending on the quality of its installation.

But did you know that there are other factors that can affect how well it ages? Our team at ARCH Exteriors, LLC, your trusted provider of high-quality replacement windows and roofing products, shares their insight.
Overall Roofing Structure
Residential roofing systems might use the same materials, but they’re essentially unique for each home in terms of construction. Not only does asphalt roof aging affect quality, but also the rate of its deterioration due to a variety of factors. These include:
- Degree of Roof Slope – Flat or low-sloped asphalt shingle roofs will have shorter lifespans than moderately sloped systems. This is because they shed moisture more slowly than steeper systems and are also more directly exposed to the sun’s UV rays.
- Ventilation – If you work with a trusted roofing company, they’ll make sure that your asphalt shingle roof has an adequate ventilation system to keep it cool. Poor ventilation will lead to warm air building up beneath your roof. reducing its expected lifespan.
- Orientation – Roof slopes that face south tend to have shorter lifespans since they’re more exposed to UV rays. They’re also more susceptible to thermal cycling and other elements such as strong winds.
- Thermal Cycling – This refers to daily temperature swings within a local climate. This can lead to constant expansion and contraction of your roof’s shingles, resulting in further deterioration over time.
Other Factors to Keep in Mind
The quality of installation can be a crucial factor in your asphalt shingle roof’s longevity and weather performance. Even if you choose top-quality shingles, they won’t be effective in protecting your home from the elements if they are installed poorly. Some of the factors we mentioned earlier can happen simultaneously on your roof, which significantly increases its deterioration rate.
