Understanding Granule Loss on New Shingles
Granule loss is a common issue that affects the performance and longevity of asphalt shingles, a popular roofing material chosen for its cost-effectiveness and aesthetic appeal. This phenomenon can be particularly concerning when observed on new shingles, as it raises questions about the quality of the roofing material and the implications for homeowners.
What Are Asphalt Shingles?
Asphalt shingles are composed of a fibreglass or organic felt base, saturated with asphalt, and topped with mineral granules. These granules serve multiple purposes they act as UV protectors, provide color and aesthetics, and help to reduce wear caused by weather elements. The integrity and function of the shingles are heavily reliant on the granules adhering properly to the surface.
The Causes of Granule Loss
Granule loss can occur due to various reasons, particularly during the installation of new shingles
1. Manufacturing Defects Sometimes, new shingles come with inherent defects due to manufacturing errors. These defects can cause the granules not to bond well with the shingle surface, leading to premature loss.
2. Installation Issues Incorrect installation can also contribute to granule loss. If shingles are nailed too tightly, it can create stress that loosens the granules. Moreover, poor ventilation in the attic can lead to overheating, which exacerbates the problem.
3. Natural Wear and Tear Even new shingles may experience some degree of granule loss due to natural wear from environmental factors such as wind, hail, and extreme temperatures. Properly installed shingles should only lose a minimal amount of granules under these conditions.
4. Improper Cleaning Homeowners sometimes clean their roofs with pressure washers. While it may seem like a good idea to remove debris, high-pressure cleaning can strip away granules and damage the shingles.
5. Poor Quality Granules The quality of the granules used on the shingles plays a significant role. Cheaper shingles may use subpar granules that are less resistant to wear and tear, making them more prone to loss shortly after installation.
Implications of Granule Loss
The loss of granules can have several consequences for the shingles and the home
- Reduced Lifespan Granule loss can significantly shorten the lifespan of the shingles. Since the granules protect against UV rays, their absence can lead to quicker deterioration of the underlying materials.
- Appearance and Aesthetics For many homeowners, the look of the roof is equally important as its durability. Granule loss can create patches of discoloration, negatively affecting the home’s curb appeal.
- Increased Energy Costs When shingles lose granules, they become more susceptible to temperature fluctuations. This can lead to increased energy costs, as your HVAC system may have to work harder to maintain a comfortable indoor environment.
- Potential for Leaks As the shingles degrade, the risk of leaks increases, which can lead to further damage within the home, necessitating costly repairs.
What Can Homeowners Do?
Homeowners should perform regular roof inspections, especially after severe weather events. If granule loss is noticed on new shingles, it’s crucial to contact the roofing contractor or manufacturer immediately. Most reputable companies offer warranties that cover manufacturing defects, and they should conduct an evaluation to determine if a replacement is warranted.
In addition, ensuring proper ventilation in the attic and avoiding pressure washing will help maintain the integrity of the shingles and their granules.
Conclusion
Granule loss on new shingles is a concerning issue that can impact the aesthetics and functionality of a roof. Understanding the causes and implications of this problem, along with proactive measures to address it, can help homeowners protect their investment and ensure their roofing system remains reliable for years to come. By staying vigilant and informed, homeowners can navigate issues related to roofing materials effectively and maintain the beauty and functionality of their homes.
