Is Granule Loss in Asphalt Shingles a Big Deal?

Understanding the condition of your roof is paramount when it comes to maintaining the integrity and functionality of your home. One of the common issues homeowners encounter is granule loss in asphalt shingles. But how significant is this problem to warrant a roof repair?

The Purpose of Granules on Asphalt Shingles

Asphalt shingles are a popular roofing choice due to their durability, affordability, and aesthetic appeal. A key component of these shingles is the ceramic-coated granules that cover their surface. These granules provide essential protection against UV rays, contribute to the shingle’s color and aesthetic qualities, and enhance the fire resistance of the roof. Additionally, they aid in shedding water off the roof, helping to prevent leaks and water damage.

Recognizing Normal Granule Loss

It’s crucial to distinguish between normal and excessive granule loss. After the installation by your roofing contractor, it’s common to notice a small amount of granules washing off into the gutters or downspouts. This usually represents loose, excess granules from the manufacturing process and is not typically a cause for concern. Normal aging of asphalt shingles will also result in gradual granule loss over time. However, when the loss accelerates or becomes more noticeable, it may signal underlying issues that require attention.

Indicators of Problematic Granule Loss

Excessive granule loss can be caused by various factors, including severe weather conditions, mechanical damage, or manufacturing defects. Key indicators of problematic granule loss include:

• Bare spots on shingles where the asphalt base is exposed
• Granules collected in gutters or at the end of downspouts in large quantities
• Premature aging of the roof despite relatively new shingles

The Impact of Granule Loss on Your Roof

The consequences of significant granule loss extend beyond mere aesthetic concerns. When the protective granules are lost, the shingles become more susceptible to damage from UV radiation, which can accelerate aging and lead to cracks and leaks. Additionally, the loss of granules compromises the roof’s ability to shed water effectively, potentially leading to moisture intrusion, mold growth, and water damage inside your home. 

Addressing Granule Loss

Homeowners noticing excessive granule loss should not delay addressing the issue. The first step is a professional roof inspection by a reputable company. They can assess the extent of granule loss, identify the underlying causes, recommend the best course of action, and provide an accurate roof estimate.

While some granule loss in asphalt shingles is normal and to be expected, excessive loss can pose a serious risk to the overall health of your roof.
