Once asphalt shingles are installed and cured, they age at what rate?

The aging of asphalt shingles primarily occurs at a slow and steady rate rather than rapidly or in a variable manner. As asphalt shingles are exposed to environmental factors such as UV radiation, moisture, and temperature fluctuations, they undergo gradual degradation over time. This includes the breakdown of the asphalt binder and the loss of granules that protect the shingles from the elements.

The aging process can be influenced by factors such as the quality of the shingles, the climate in which they are installed, and the maintenance provided. However, typically, this degradation follows a somewhat predictable pattern, leading to the conclusion that the rate of aging is slow and steady throughout the lifespan of the shingles. Understanding this aspect helps homeowners and inspectors anticipate the performance and lifespan of the roofing material, leading to better maintenance and replacement planning.
