Asphalt shingles remain the most popular roofing option for homeowners. They can effectively protect the home from weather damage and are relatively easy to install. However, constant exposure to the elements eventually results in weathering, a natural process that causes asphalt shingles to deteriorate over time.
In this post, residential roofing experts examine the life-cycle of asphalt shingles and what occurs as they age.
Installation
The process of deterioration begins as soon as the shingles are installed on the roof and exposed to weather conditions. Since the new asphalt layer has not yet had a chance to cure, the speedy aging activity continues for a short period of time until the asphalt layer becomes tougher and more durable. Minor granule loss happens as a result of excess granules separating from the shingles. These granules are washed away by rainwater.
Prolonged Aging
Asphalt shingles enter a slow, prolonged period of aging after the curing activity is completed. According to expert roofers, deterioration starts on a minute level, with microscopic cracks appearing in the asphalt surface. Other noticeable changes include the loss of a few granules and evaporation of volatiles — compounds that are added to the asphalt to keep shingles waterproof and flexible.
Accelerated Deterioration
This stage is where common asphalt shingle issues begin to appear. For example, surface cracking can expose more asphalt to ultraviolet radiation and thermal cycling can cause asphalt to split. In cold climates, damage to shingles may increase due to freezing.
How to Slow Down Aging on Asphalt Shingles
Copper and roof coatings can help lessen the impact of weather elements on various roofing materials, slowing down the aging process of your asphalt shingle roof.
