The urban heat island (UHI) effect occurs when cities trap and radiate more heat than rural areas, leading to higher temperatures, increased energy demand, and reduced air quality. Traditional dark roofing shingles absorb solar heat, contributing to this problem.
In Kerala’s dense urban zones, high heat absorption not only increases cooling costs but also stresses roofing materials. Reflective roofing shingles are one way to combat this.
How Reflective Shingles Mitigate UHI
Higher Solar Reflectance
Shingles with a high Solar Reflectance Index (SRI) bounce more sunlight away, reducing heat absorption.
Example: Armourshake Roofing Shingles use light-colored granules for improved reflectivity.Reduced Surface Temperatures
Borja Tech Tiles and other reflective tiles can be 10–15°C cooler than standard shingles under direct sunlight.Lower Ambient Air Heating
By reducing the temperature of each rooftop, reflective shingles help bring down neighborhood-wide air temperatures, particularly in hot afternoons.
Quantifying the Benefits: Measurable Impact
Surface Temperature Reduction: Studies show reflective shingles can lower rooftop surface temps by up to 30%.
Cooling Cost Savings: Homes with high-SRI shingles can save 10–20% on summer cooling bills.
Extended Roof Lifespan: Lower heat exposure slows photodegradation in architectural roofing shingles and asphalt shingles.
