Algae Coatings Cut Metal Roof Temps by 25°F
Algae-based roof coatings lower metal roof temperatures by up to 25°F, which reduces energy costs and extends roof lifespan. These coatings integrate reflective minerals with living algae to convert sunlight into biological energy rather than heat. Suited for humid or sunny regions, they perform best with thorough preparation, ongoing maintenance, and documented results for optimal, sustainable benefits.
