Keep reading to learn more about granule loss on shingles and how you can combat it to keep your roof looking good and staying resilient!

What is Granule Loss?

Granule loss occurs when the protective granules on the surface of asphalt shingles start to wear away or detach from the shingle. These granules are an essential component of asphalt shingles, providing protection against UV rays, weathering, and impact damage. When granules are lost, it can leave the underlying asphalt substrate exposed, potentially compromising the integrity of the shingle.

3 Signs of Granule Loss


Below we’ll cover 3 key signs that you may have asphalt shingle granule loss.

1. Visible Granule Accumulation

Keep an eye on your gutters, downspouts, and the ground around your home for signs of granule accumulation. If you notice an excess of granules, it could indicate that your shingles are losing their protective coating.

Also, granule buildup in your gutter system can lead to clogs and drainage issues, so it’s essential to address the underlying cause promptly.

2. Bare Spots on Shingles

Take a close look at your shingles for any areas where the granules have worn away, leaving behind bare spots or shiny patches. These bald spots expose the underlying asphalt substrate, making the shingles more vulnerable to damage from UV rays, moisture, and other environmental factors.

So if you spot bare spots on your shingles, it’s crucial to address them promptly to prevent further deterioration and extend the lifespan of your roof.

3. Discoloration

Granule loss can also manifest as discoloration or fading of your shingles. As the protective granules wear away, the underlying asphalt may become visible, resulting in changes in color or texture. Discolored shingles not only detract from the appearance of your roof but may also indicate underlying damage or deterioration.

If you notice any discoloration on your shingles, it’s essential to investigate further to determine the cause and take appropriate action to protect your roof. Regular inspections and maintenance can help catch discoloration early and prevent more significant issues down the line.

Causes of Granule Loss

  • Normal Wear and Tear: Over time, exposure to the elements, including sunlight, rain, wind, and hail, can cause the granules on shingles to loosen and dislodge.
  • Poor Quality Shingles: Low-quality or improperly manufactured shingles may experience premature granule loss due to inadequate adhesion or bonding of the granules to the shingle surface.
  • Improper Installation: Shingles that are installed incorrectly or with insufficient adhesive may be more prone to granule loss, especially in high-wind or storm-prone areas.

Effects of Granule Loss

  • Reduced Weather Resistance: Granule loss compromises the protective barrier of the shingles, making them more susceptible to damage from UV rays, moisture, and thermal cycling.
  • Decreased Lifespan: Shingles with significant granule loss may have a shorter lifespan than intact shingles, requiring premature replacement or repair.
  • Aesthetic Concerns: Granule loss can detract from the appearance of your roof, causing it to look aged, worn, or patchy. This can negatively impact the curb appeal and value of your home.

How to Effectively Prevent Granule Loss


Let’s go over a few easy ways you can prevent granule loss on your shingles and keep your roof in top-notch condition.

Choose High-Quality Shingles

When selecting shingles for your roof, prioritize quality over cost. Look for products from reputable manufacturers with a proven track record of durability and longevity. High-quality asphalt shingles are designed to withstand the rigors of the elements, including harsh sunlight, heavy rain, and strong winds.

By investing in premium shingles, you can ensure that your roof is equipped to handle whatever Mother Nature throws its way, minimizing the risk of granule loss and other potential issues down the line.

Proper Installation

The importance of proper installation cannot be overstated when it comes to preventing granule loss. Even the highest-quality shingles can fail prematurely if they are not installed correctly. That’s why it’s crucial to hire experienced professionals who are familiar with the specific installation requirements of asphalt shingles.

From ensuring proper alignment and fastening to sealing vulnerable areas like valleys and roof edges, proper installation techniques are essential for maximizing the performance and longevity of your roof. Don’t cut corners when it comes to installation—investing in quality workmanship upfront can save you time, money, and headaches in the long run.

Regular Maintenance

In addition to choosing high-quality shingles and ensuring proper installation, regular maintenance is key to preserving the integrity of your roof and minimizing the risk of granule loss. Keep your roof clean and free of debris by regularly removing leaves, branches, and other debris that can accumulate on the surface. Trim back overhanging branches to prevent them from rubbing against the shingles and causing abrasion.

Likewise, inspect your roof regularly for signs of damage or wear, such as missing or damaged shingles, and address any issues promptly to prevent further deterioration. By staying proactive with maintenance, you can extend the lifespan of your roof and minimize the likelihood of granule loss and other problems.

Don’t Let Granule Loss Rain on Your Roof Parade

While granule loss may be a cause for concern, it doesn’t necessarily mean your roof is on its last legs. By understanding the causes and effects of granule loss and taking proactive measures to prevent it, you can ensure your roof stays in tip-top shape for years to come. So keep an eye out for those pesky granules, and don’t hesitate to reach out to a roofing professional if you have any concerns.
