What type of rooftop would actually reduce the heat island effect?

Green roofs and cool roofs are effective in reducing the urban heat island effect. Green roofs, covered with vegetation, provide insulation and absorb sunlight, while cool roofs, coated with reflective materials, reflect more sunlight and absorb less heat. Both types help lower ambient temperatures, improve air quality, and enhance urban biodiversity. Implementing these roofing solutions can significantly mitigate the heat generated in urban areas.
