Granules Coming Off New Roof Understanding the Reasons and Implications

When homeowners invest in a new roof, they expect it to provide shelter and protection for many years. However, a common concern that arises shortly after installation is the shedding of granules from asphalt shingles. These tiny bits of material, which are often noticed in gutters, downspouts, yards, or simply on the ground, can be alarming for homeowners. Understanding the reasons behind granules coming off a new roof, the implications of this occurrence, and what steps should be taken can help alleviate worries and ensure the longevity of the roof.

Why Do Granules Come Off?

Asphalt shingles are composed of a fiberglass mat, asphalt, and a layer of granules, typically made from crushed stone or ceramic. These granules serve several purposes they provide color, protect the asphalt from ultraviolet (UV) rays, and add weight, which helps keep the shingles in place. There are a few key reasons why granules might come off a new roof shortly after installation

1. Manufacturing Defects Occasionally, there are flaws in the production process that result in poorly bonded granules. If the adhesive used to attach the granules is not properly applied, they may loosen and fall off, particularly during the early stages of installation when the shingles are settling.

2. Installation Issues If the shingles were not installed correctly, this could lead to premature granule loss. Whether it’s improper nail placement or inadequate sealing, an unprofessional installation can exacerbate the shedding of granules.

3. Weather Conditions Extreme weather conditions can affect a new roof. High winds or hailstorms can dislodge granules, especially during the first few months after installation when new shingles may still be adjusting to their environment.

4. Normal Settling It’s important to note that some granule loss is normal during the settling period of new shingles. As the roof adjusts and fully adheres, some granules may loosen and fall off, especially during heavy rains.

Implications of Granule Loss

While some granule loss may be considered normal and temporary, extensive shedding can indicate potential problems. Granules protect the underlying asphalt layer from UV rays, and their loss can lead to several issues

- Increased Vulnerability Without the protective layer of granules, the asphalt becomes susceptible to sun damage, which can lead to cracking and deterioration.

- Reduced Lifespan A roof that experiences significant granule loss will likely require replacement sooner than expected, which can lead to added costs for homeowners.

- Aesthetic Concerns As granules come off, the appearance of the roof may change. Homeowners often desire a uniform look for their roofs, and noticeable bald spots can detract from their home’s curb appeal.

What to Do If Granules Are Coming Off

If you’ve noticed granules collecting in your gutters or yard shortly after installing a new roof, here are some steps you can take

1. Inspect Conduct a thorough inspection of your roof. Look for any visible signs of damage or unusual wear, particularly in areas that are prone to wind exposure.

2. Consult the Installer If you notice abnormal granule loss, reach out to your roofing contractor. A reputable installer will conduct a follow-up inspection and determine if the loss is within normal limits or indicative of a larger problem.

3. Document the Issue Take pictures of the granules in various locations around your home, and keep a record of when you observe the loss. This documentation can be useful if you need to discuss the issue with the installer or a warranty provider.

4. Consider Warranty Claims Many roofing materials come with warranties that cover manufacturing defects. If you suspect that the granule loss is due to a defect, check the warranty details and consult with the manufacturer.

Conclusion

While seeing granules coming off a new roof can be troubling, it’s important to understand the potential causes and implications. While some loss may be normal, significant shedding could indicate underlying issues that need to be addressed. Homeowners should be proactive and vigilant, maintaining open communication with their roofing contractor to ensure the integrity and longevity of their investment. A sturdy, well-maintained roof is essential for protecting your home, and understanding the intricacies of your roofing materials will help you keep it in top condition for years to come.
