Why Homeowners in Hawaii Are Choosing Eco-Friendly Roofing
In Hawaii, where sunshine is abundant and energy efficiency can make a big difference in cooling costs, eco-friendly roofing materials are gaining popularity. These roofing systems are designed to reduce heat absorption, lower energy use, and minimize environmental impact — all while offering the strength needed for island weather.
At Kapili Roofing & Painting, we’ve installed many eco-conscious roofing systems that perform exceptionally well in Hawaii’s unique climate, from Waipahu to Maui and Kauai. Here’s how they compare in durability, efficiency, and overall value.
Types of Eco-Friendly Roofing Materials & Their Performance
Cool Roof Shingles vs Standard Roof Shingles
Benefits in Hawaii: Cool roof shingles help maintain comfortable indoor temperatures even during the hottest, sunniest afternoons common across the islands. By reflecting a significant amount of solar energy, they minimize heat transfer into your home, easing the workload on air conditioning systems throughout the day.
Kapili’s Approach: We often recommend GAF Timberline® Reflective Series and CertainTeed Solaris® shingles to Hawaii homeowners who want to achieve a balance of high performance, modern aesthetics, and significant energy savings. Both products utilize advanced reflective granule technology, helping to reduce surface temperatures and enhance long-term durability under intense island sun.
Metal Roofing
Performance: Engineered for longevity and high performance, metal roofing systems are among the most durable options available to Hawaii homeowners and commercial property owners. These roofs feature highly reflective surfaces that efficiently deflect solar radiation, helping to keep attic spaces and building interiors cooler in intense sun conditions. Certified for outstanding recyclability, most metal roofing materials are manufactured using a significant portion of recycled content and can be fully recycled at the end of their service life, minimizing environmental impact. With an expected lifespan of 40 years or more even in Hawaii’s challenging climate, metal roofs offer long-term protection against wind, rain, and salt air, which are regular stressors across the islands.

Kapili’s Approach: We recommend premium metal roofing solutions such as Great American Shake aluminum panels and Holcim Elevate standing seam roofing panels. These systems are engineered to deliver advanced UV protection, exceptional longevity, and robust wind resistance. Both options are designed for minimal environmental impact while maintaining the durability and energy efficiency required for Hawaii’s unique climate.
Roof Coating Systems
Performance: Advanced silicone or acrylic roof coatings offer a versatile solution for extending the life of existing roofing systems, making them an ideal choice for both commercial and residential properties seeking improved protection and efficiency. These coatings form a seamless, resilient barrier that significantly increases a roof’s reflectivity, reducing heat absorption from the sun and helping to maintain cooler building interiors—especially important in Hawaii’s hot, sunny climate.Benefits in Hawaii: Roof coating systems are especially effective for flat or low-slope roofs, helping to reflect solar heat away from the building and maintain lower interior temperatures throughout the day. This enhanced reflectivity not only supports greater energy efficiency but also reduces cooling costs during Hawaii’s hottest months.
Kapili’s Approach: We apply coatings from Tropical Silicone and Gaco, leading manufacturers known for their advanced, high-performance roofing solutions. These coating systems deliver significant reductions in surface temperatures and solar heat gain, keeping Hawaii properties cooler and more energy efficient.
