In regions like Kerala, where sunshine and humidity dominate much of the year, rising indoor temperatures often lead to soaring cooling costs. One smart solution that’s gaining momentum is the use of reflective roof shingles. Marketed as energy-saving, eco-friendly, and durable, these shingles claim to reduce indoor temperatures and even cut cooling bills by up to 30%.
But is this claim backed by science—or just another roofing myth? Let’s dig into the facts.
What Are Reflective Roof Shingles?
Reflective shingles, also known as cool roof shingles, are specially engineered to reflect more sunlight and absorb less heat than standard shingles. They usually contain light-coloured granules, infrared-reflective pigments, or metal oxide coatings that enhance solar reflectance.
They are available in:
Asphalt shingles with reflective granules
Metal roofing systems
Solar-compatible tiles
Clay and ceramic tiles with reflective glaze

How Do Reflective Shingles Reduce Cooling Bills?
☀️ The Science of Solar Reflectivity
Standard dark shingles can absorb up to 90% of the sun’s heat, transferring it to the attic and indoor spaces. Reflective shingles, on the other hand, can reflect 30–60% of solar radiation—significantly reducing heat gain.
This means:
Cooler attic temperatures
Reduced load on air conditioners
Lower indoor temperatures (by up to 5–8°C)
Less energy required to maintain comfort
Can They Really Reduce Cooling Bills by 30%?
✅ Yes—In the Right Conditions
According to studies by the U.S. Department of Energy and global roofing research bodies, reflective shingles can reduce cooling energy consumption by 10–30%, depending on:
| Factor | Impact |
|---|---|
| Climate | Hot, sunny regions like Kerala benefit the most |
| Roof orientation | South and west-facing slopes gain maximum benefit |
| Ventilation | Proper attic ventilation enhances performance |
| Shingle quality | Reflective granules or coatings must be high-grade |
So yes, under ideal installation and material conditions, you can realistically cut cooling bills by up to 30%.
Benefits of Reflective Roofing Beyond Energy Savings
🌬️ Improved Comfort
Indoor spaces stay cooler naturally—even during power cuts.
🌱 Lower Carbon Footprint
Reduced AC use = less power consumption = lower greenhouse emissions.
🔧 Longer Roof Lifespan
Reflective shingles reduce thermal shock, preventing early degradation and granule loss.
🏠 Better EPC Ratings
By improving building insulation and thermal efficiency, reflective shingles contribute to higher Energy Performance Certificate (EPC) scores—especially in regions where EPC awareness is growing.
