Roof shingles, especially those installed in regions like Kerala, are not just aesthetic elements—they serve as critical components in protecting your building from environmental damage. But over time, you may notice shingle granules appearing in your gutters or around the base of your building. This granule loss may seem minor, but it carries major implications for both the lifespan of your roof and your Energy Performance Certificate (EPC) rating.
At Scaffs India, we believe understanding granule loss is essential for homeowners and builders aiming for long-lasting and energy-efficient roofing solutions.
What Is Granule Loss in Roof Shingles?
Roof shingles—especially asphalt-based ones—come coated with ceramic-coated mineral granules. These granules protect the shingle from UV rays, fire hazards, and weather damage. Over time, however, granules can begin to detach due to:
Aging and wear
Heavy rain and wind
Foot traffic or poor installation
Improper ventilation
Low-quality materials
Shingle Lifespan: How Granule Loss Accelerates Roof Ageing
Granule loss significantly impacts the performance and durability of your roof:
🔹 Loss of UV Protection
Without granules, the shingle base gets exposed to direct sunlight, leading to faster degradation.
🔹 Faster Moisture Penetration
Granules help water slide off the roof. Their absence allows moisture to seep in, risking rot and mould.
🔹 Weakened Fire Resistance
Granules add fire resistance—especially important in high-temperature regions like Kerala.
🔹 Higher Risk of Leaks
Bald shingles are more prone to cracks and splits, which lead to water leaks.
Once granule loss starts, the roof’s overall lifespan reduces significantly unless addressed with repairs or timely replacement.

EPC Ratings and the Roof: What’s the Connection?
The Energy Performance Certificate (EPC) assesses how energy-efficient a property is. It directly impacts your property value, rental appeal, and legal compliance for selling or leasing in many parts of India and abroad.
✅ How Granule Loss Affects EPC Ratings
Lower Insulation Efficiency
Granule loss leads to a hotter attic in summer and colder spaces in winter, increasing energy usage for cooling/heating.Decreased Reflectivity
Reflective granules reduce solar heat absorption. Losing them means your building absorbs more heat, raising your energy bill.Compromised Thermal Envelope
A deteriorating roof reduces the overall performance of the building envelope, which is a crucial factor in EPC assessments.More HVAC Load
As insulation and reflectivity suffer, your HVAC system works harder, consuming more power and lowering your EPC score.
To avoid this, consider modern solutions like Solar Roof Tiles and Borja Tech Energy-Efficient Tiles from Scaffs India.
Signs of Excessive Granule Loss: What to Watch For
Granules in the gutter or downspout
Bald spots on your shingles
Patchy discolouration
Uneven or curling shingles
Indoor temperature swings
