If you’ve noticed small sand-like particles collecting in your gutters or around your home’s foundation, you may be seeing granule loss from asphalt shingles. These tiny ceramic-coated granules are an essential part of your roof’s protection system. But when they start to fall off, homeowners often wonder: Is this normal wear, or a sign of roof trouble?
At Scaffs India, we supply and install asphalt roofing shingles in Kerala designed to withstand heavy rains, humidity, and strong winds. Here’s what you need to know about granule loss, when it’s harmless, and when it’s a warning sign.
🏠 Why Asphalt Shingles Have Granules
Granules aren’t just decorative—they play a key role in roof performance:
UV Protection – They shield the asphalt layer from sun damage.
Weather Resistance – They provide an extra layer against rain, wind, and impact.
Aesthetic Appeal – Granules come in different colors to suit designer shingles.
Fire Resistance – They help shingles achieve fire safety ratings.
Without granules, shingles age faster, dry out, and become brittle.
✅ When Granule Loss is Normal
New Roof Shedding
Freshly installed shingles often lose excess granules left over from manufacturing.
This usually happens in the first few months and is not a concern.
Minor Wear Over Time
All shingles gradually shed granules with age.
Light granule loss spread across the roof is part of normal aging.
⚠️ When Granule Loss is a Warning Sign
Bald Patches
If you see exposed black asphalt, the shingle’s protective layer is gone.
This leaves the roof vulnerable to UV rays and leaks.
Clogged Gutters with Granules
Large amounts of granules washing into gutters signal accelerated wear.
Storm Damage
Heavy rain, hail, or debris impact can knock granules loose.
This type of damage often affects isolated areas of the roof.
Old Age
Asphalt shingles near the end of their life cycle lose granules rapidly.
For example, 3-tab shingles usually last 15–20 years, while architectural shingles can last longer.
🔧 What to Do if You Notice Granule Loss
Inspect the Roof Closely – Check for bald spots or curling shingles.
Schedule Professional Inspection – Roofing experts can assess whether the roof needs repairs or replacement.
Consider Upgrading – Options like Dynasty Shingles and Armourshake Designer Shingles provide stronger resistance to wear.
✅ Scaffs India’s Recommendation
In Kerala’s heavy monsoon climate, granule loss can accelerate due to rainfall impact, strong winds, and humidity. That’s why we recommend:
Architectural Shingles for longer life and impact resistance.
Premium Designer Shingles for both aesthetics and durability.
Regular roof inspections to detect early warning signs.
📞 Final Word
Granule loss is sometimes normal, especially after a new installation, but excessive or patchy granule loss is a warning sign that your roof may need repairs or replacement.
