Is Granule Loss in Asphalt Shingles a Big Deal?

Asphalt shingles are one of the most popular residential roofing systems, offering durability and aesthetic appeal. However, one issue that often comes up with these roofs is granule loss. While it might seem minor, understanding the importance of granule loss, its causes, and how it impacts your roofing can save you from future headaches and ensure your home remains protected.

Understanding Granule Loss in Asphalt Shingles

Granule loss refers to the shedding or erosion of the ceramic-coated granules that cover the surface of asphalt shingles. These granules are not just for show; they play a crucial role in protecting the asphalt layer from UV rays and physical damage. They also contribute to the shingle’s color and reflective properties, affecting your home’s appearance and energy efficiency.

Causes of Granule Loss

Several factors can lead to granule loss, and understanding them can help you take preventive measures. These factors include the following:

• Age of the Roof 

Local roofing contractors can attest that over time, natural wear and tear can cause granules to loosen and fall away. That’s why older roofs are more susceptible to significant granule loss.

• Physical Damage

Severe weather conditions such as hail storms, heavy rains, or high winds can physically displace granules.

• Improper Installation

Installing shingles incorrectly can increase vulnerability and accelerate granule loss.

• Manufacturing Defects

While less common, defects during the manufacturing process can also cause premature granule loss.

Is Granule Loss a Serious Concern?

Asphalt shingles often experience granule loss, particularly after new roof installation or severe weather events. However, excessive granule loss can expose the asphalt layer, leading to accelerated roof aging, decreased protection against the elements, and potentially costly repairs down the line. 

How to Identify and Address Granule Loss

Regular inspection of your gutters and downspouts can reveal accumulations of granules, indicating loss from your shingles. Moreover, visible bare spots on your shingles or a noticeable change in roof color are signs that your roof may be experiencing significant granule loss. If you suspect that your asphalt shingles are shedding granules excessively, immediately contact a reputable roofing professional. A thorough inspection can determine the extent of the issue and whether specific repairs or a complete roof replacement is necessary.

Protecting Your Roof From Premature Granule Loss

To mitigate the risk of premature granule loss, consider the following:

• Regular Maintenance

Routine inspections and maintenance can identify potential issues before they escalate.

• Quality Materials

When replacing your roof, choose high-quality materials from reputable manufacturers to ensure longevity.

• Professional Installation

To prevent installation errors, make sure to engage professional and quality roofing services for your project.
