There’s no doubt that asphalt shingles are the most popular roofing material in the United States, all the more here in South Carolina. Their aesthetics, durability, versatility, and affordability make them an ideal option for most homeowners. One of their greatest features is the granules on their surface. These particles add to their reliability by increasing the shingles’ stability and blocking UV rays that damage them. Like many roof features, though, asphalt granules can wear down over time, affecting both the curb appeal and structural integrity of the roof. If the damage is too extensive, you might have to call a residential roofing company in Columbia for repairs.

Fortunately, with a little bit of knowledge and routine maintenance, you can slow this process down. Understanding the causes of granule loss can help you delay the aging process of your roof and help it last longer. International Construction Services, Inc. shares some of the top reasons behind asphalt shingle granule loss in this post.

Extreme Weather Conditions

Strong winds, rain, and hailstorms can loosen granules or even dislodge your asphalt shingles altogether. No matter how strong or reliable your roof is, it can still be vulnerable to storm damage. That said, it’s highly crucial to hire professional roofing services after an extreme weather event, you can get a proper assessment on the condition of your entire system and fix issues before they get even bigger. 

Presence of Moss

Moss is usually an aesthetic issue. Unsightly dark streaks on a roofing system can definitely drag down your home’s curb appeal. However, in certain cases, moss can cause granules to fall from your shingles. Thriving in cool and damp environments, it can hold moisture against the surface of your asphalt shingles. When temperatures drop, moisture trapped by moss freezes, potentially damaging the surface of your shingles. Be sure to call in a professional to help remove moss from your roof permanently and prevent it from further damaging your shingles.

Installation Errors

Is it possible for your roof to shed an excessive amount of granules even though it was just installed? The short answer is yes. When that happens, the poor-quality installation might be to blame. Keep in mind that only qualified residential roofing contractors should perform huge roofing works such as roof installation. With trustworthy experts doing the work, you can be sure your new roof will deliver a high level of performance for many years. 


The South Carolina climate can be a bit harsh to shingles. The heat and sunlight can cause blistering, which is one of the most damaging ways the shingles are worn down. The blisters on the surface of the shingles form when moisture gets trapped inside them. Once heat and sunlight reach the moisture-filled shingles, they will eventually expand. Blistering shingles are a sign that your roof needs immediate repairs.

Proper and regular maintenance can make your asphalt shingle roof last longer. Repairs should be done right away before they cause even bigger problems.
