Asphalt shingles are a popular roofing choice for their durability, aesthetics, and affordability. However, granule loss is a common issue that signals the beginning stages of shingle wear and tear. Recognizing this early can save homeowners from costly repairs and extend the life of their roofs.
In Kerala’s tropical climate, with its heavy rains and intense sun, monitoring granule loss is crucial for maintaining a roof’s performance.
What Are Granules in Asphalt Shingles?
Granules are the tiny, colored ceramic-coated particles embedded on the surface of asphalt shingles. They serve multiple purposes:
Protect shingles from UV radiation.
Add color and aesthetic texture.
Provide fire resistance.
Enhance impact durability.
Causes of Granule Loss
Natural Aging: Over time, granules loosen as part of normal weathering.
Heavy Rainfall & Wind: Kerala’s monsoons accelerate granule dislodgement.
Hail & Physical Impact: Debris or hail can dislodge granules prematurely.
Improper Installation: Poor handling or incorrect fastening methods.
Foot Traffic on Roof: Walking on shingled roofs wears down granules.
Manufacturing Defects: Low-quality shingles may have weaker granule adhesion.
Early Signs of Granule Loss to Watch For
Granules in Gutters and Downspouts: An accumulation of sandy particles.
Bald Spots on Shingles: Areas where the black asphalt layer becomes visible.
Color Inconsistencies: Shingles looking patchy or faded.
Roof Surface Sheen: Exposed asphalt gives shingles a shiny appearance.
Granule Wash-Off after Heavy Rains: Particularly after intense Kerala monsoon storms.
Why Granule Loss is a Serious Concern
UV Damage: Exposed asphalt deteriorates rapidly under sunlight.
Moisture Intrusion: Loss of granules reduces water-shedding efficiency.
Reduced Impact Resistance: Shingles become more vulnerable to hail and debris.
Decreased Roof Lifespan: Accelerates the aging process of the entire roofing system.
