  • Deterioration Due to Normal Roof Aging vs. Roof Damage

As long as your roofer installs your asphalt shingles properly, and you maintain them regularly, expect them to last for at least 20 years. It’s normal for roofs to deteriorate as they age, but damage can also speed up their aging process. Like any other part of your home, you will eventually need to replace it. 

Roof Aging

Here’s the difference between roof deterioration due to normal aging and damage. 

Roof Aging

Dark Spots on the Surface

Shingles have granules, which are sediments that give them color and added protection from the elements. Some of these granules can fall during shipping and installation, but those are usually just excess from manufacturing. Dark spots can form on your roof’s surface due to significant granule loss. 

Fading Color

Asphalt shingles naturally lose color as they age, especially ones in darker hues. It’s what years of exposure to direct sunlight can do. Faded shingles do not necessarily have damage, or you need a roof repair. However, they can affect your home’s curb appeal. It’s also a common sign that your roof is reaching the end of its lifespan.

Sunlight Exposure

The sun’s ultraviolet (UV) rays can speed up the deterioration of your roof. It’s the reason west and south-facing roofs tend to look older faster. If your roof has reflective coatings, they can lower heat absorption and make your roof less prone to premature aging. 

Roof Damage

Vent Damage

Damaged vents must be addressed immediately. Failure to deal with this issue can result in significant damage and shorten the lifespan of your roof. 

Damaged or Missing Flashing

You can usually find flashing around the trim, chimneys, skylights, valleys and other roof protrusions. The bottom part of the flashing can lift and allow water to seep into your home due to thermal expansion and contraction. 


Sagging is a strong indication of roof deterioration due to poor installation. It could also occur when your roof has too many layers of shingles. A sagging roof usually needs to be replaced immediately before it collapses.
