Composition roof: Everything you need to know
January 19, 2025Granule loss is one of the most common issues homeowners notice with asphalt shingles. But does this mean you need a new roof?
Let’s break it down and understand the role of granules, what granule loss signifies, how to determine if your roof needs replacement, and your options.
What are shingle granules and why are they important?

Shingle granules are tiny mineral particles embedded on the surface of asphalt shingles. These granules serve several crucial purposes:
- UV Protection: They shield the underlying asphalt layer from harmful ultraviolet rays, which can degrade the shingle over time.
- Aesthetic Appeal: Granules come in various colors, adding to the visual appeal of your roof.
- Fire Resistance: They improve the shingle’s fire resistance by providing an additional layer of protection.
- Durability: Granules enhance the overall durability of shingles, protecting them from weathering and erosion.
When granules begin to shed, it can compromise the performance and lifespan of your roof.

Is granule loss normal?
Some granule loss is normal, especially with a new roof. During the manufacturing process, excess granules may not adhere to the shingles and can come loose when installed. This initial shedding, often noticed in gutters or downspouts, is no cause for concern.
However, granule loss in older roofs could indicate:
- Aging Shingles: Granules naturally wear off as shingles age, reducing their ability to protect your home.
- Severe Weather: Hailstorms, high winds, and heavy rain can dislodge granules, leading to premature wear.
- Poor Installation: Improperly installed shingles may experience early granule loss.
- Foot Traffic: Walking on your roof can loosen granules, especially if done frequently or without care.
- Defective Shingles: Manufacturing defects can lead to accelerated granule shedding, though this is less common (rare).
Signs that granule loss may require action
While some granule shedding is harmless, there are situations where it signals a bigger problem:
- Exposed Asphalt Layer: If the asphalt beneath the granules is visible, your shingles are more vulnerable to UV damage and water infiltration.
- Granule Buildup in Gutters: Excessive granules in your gutters might indicate significant wear.
- Bald Spots on Shingles: Noticeable bare patches are a sign that the shingles are nearing the end of their lifespan.
- Discoloration: Uneven or faded shingles may point to granule loss caused by weathering.
- Leaky Roof: If you’re experiencing leaks, granule loss could be a contributing factor.

Do you need a new roof?
Whether granule loss means you need a new roof depends on several factors:
- Age of the Roof: Asphalt shingles typically last 20-30 years. If your roof is near the end of its lifespan, replacement might be necessary.
- The extent of Damage: Is the granule loss isolated to a few shingles or widespread? Extensive granule shedding often requires a roof replacement.
- Inspection Results: Have a professional roofing contractor assess the condition of your shingles. They can identify whether the damage is cosmetic or structural.
- Weather Exposure: Homes in areas with extreme weather conditions might require more frequent roof replacements due to accelerated wear.
Options for addressing granule loss
If granule loss is detected, here’s what you can do:
- Roof Repairs: Replace individual shingles with significant granule loss if the problem is isolated.
- Protective Coatings: Some coatings can prolong the life of your shingles by enhancing their resistance to UV rays and moisture.
- Full Roof Replacement: If granule loss is extensive, a new roof might be the best option to protect your home.
Preventing granule loss in the future

To prolong the life of your shingles and minimize granule loss:
- Regular Inspections: Have your roof inspected annually and after major storms.
- Clean Gutters: Ensure proper drainage to prevent water pooling, which can deteriorate shingles.
- Avoid Walking on the Roof: Limit foot traffic to reduce unnecessary wear.
- Choose High-Quality Shingles: Premium shingles often have better granule adhesion and durability.
What causes granule loss?
Granule loss in shingles can occur for several reasons, each pointing to a different aspect of roof health or environmental impact. Understanding these causes is essential for determining whether your roof needs repair, replacement, or simple maintenance.
1. Aging and Wear: Over time, shingles naturally deteriorate due to constant exposure to the elements. Asphalt shingles typically last 20 to 30 years, but as they age, their granules start loosening and falling off. This is a sign that the shingles are reaching the end of their lifespan.
2. Weather Conditions: Extreme weather events like hailstorms, high winds, and heavy rains can dislodge granules from shingles. In particular, hail can create dents that knock granules loose, while strong winds can strip the roof’s surface layer.
3. Improper Installation: Poor installation can lead to granule loss earlier than expected. For instance, overdriven nails or improper adhesive application can weaken the bond between the granules and the shingle surface.
4. Roof Traffic: Walking on your roof, whether for repairs or inspections, can disturb the granules. This is especially true if care isn’t taken to distribute weight evenly or if the surface is already weakened.
5. Poor Quality Shingles: Lower-quality shingles tend to have less durable granule coatings. These products are more prone to early granule loss, especially under harsh weather conditions.
By identifying the root cause, you can take targeted action to address the issue, whether through simple maintenance, repairs, or a full roof replacement.
Final thoughts
Granule loss doesn’t always mean you need a new roof, but it’s a sign that your shingles need attention. By understanding the causes and taking proactive measures, you can extend the lifespan of your roof and protect your home. When in doubt, consult a professional roofer to determine the best course of action.
