What Happens as Asphalt Shingles Age?

Asphalt shingles are a popular and economical choice for many homeowners. However, as with any roofing material, they will begin to show signs of age over time. It is important to be aware of these signs to protect your home from the elements and avoid shouldering a high roof repair cost.


As asphalt shingles age, they can begin to curl along the edges. This is caused by the heat from the sun. And in addition to making your roof look bad, it leaves your roof vulnerable to leaks and water damage. It also indicates that it is time for a new roof.

Loss of Granules

Asphalt shingles is covered with small granules that protect the roof from ultraviolet rays. Over time, these granules can begin to fall off and leave your roof exposed. If left unchecked, this could lead to an increased risk of leaks and water damage.

Cracked Shingles

The extreme temperatures of summer and winter can cause the asphalt shingles to crack or split. This exposes the underlying material, leaving it vulnerable to moisture and other damage. If you notice any cracks or splits in your shingles, it is important to have them repaired as soon as possible.

Moss or Algae Growth

Moss and algae growth on asphalt shingles is a common problem in humid climates. Not only does this growth look unsightly, but it also accelerates the aging of the shingles and causes water damage.

How to Extend the Life of Asphalt Shingles 

There are several things you can do to extend the life of your asphalt shingle roof:

  • Removal of Debris: Regularly removing debris such as leaves, branches, dirt and other items from your roof will help keep your shingles in good condition for longer.

  • Regular Inspections: Have a qualified professional roofer inspect your roof at least once a year to check for any signs of wear or damage that may need attention.

  • Regular Maintenance: Performing regular maintenance, such as cleaning gutters and downspouts, trimming overhanging trees or branches, fixing loose flashing around chimneys or vents, etc., will help keep your roof in top shape for many years to come.

  • Proper Installation: Ensuring that all materials used in the installation process are high-quality and properly installed is essential if you want your new asphalt shingle roof to last its full life expectancy (typically 15-30 years).
