NYC Cool Roofs Program

NYC Cool Roofs is an initiative to mobilize volunteers to coat the rooftops of participating buildings with reflective, white coating to help reduce cooling costs, energy usage, and greenhouse gas emissions. The initiative will help the City meet PlaNYC's goal of reducing the City's greenhouse gas emissions by 30% by 2030.

Since most New York City roofs are dark or black in color, they retain the sun's rays as heat, increasing summer roof temperatures and energy demand. Dark roofs also contribute to the "urban heat island effect," a phenomenon where the City can be 6 to 8 degrees warmer than surrounding suburban areas. Coating all eligible dark rooftops in New York City could result in up to a 1 degree reduction of its ambient air temperature. You can get information by sending an email to
