As summer temperatures climb, New York City is pushing a simple but effective solution to keep buildings cooler and cut energy costs: free cool roofs. The program, run by the NYC Department of Small Business Services, the Mayor's Office of Climate and Environmental Justice, and The HOPE Program, has been coating rooftops with reflective white paint since 2015. It's a zero-cost way for eligible buildings to fight the heat without cranking up the AC.
Dark asphalt roofs can hit a scorching 190°F on a typical summer day, turning buildings into ovens and driving up energy use. By applying a specialized reflective layer, the program reduces thermal absorption and can lower indoor temperatures by up to 30%. That means more comfortable spaces for residents, students, and patients, and lower electricity bills for building operators.
Who can get a free cool roof?
The program prioritizes buildings that serve the community: nonprofits, affordable housing complexes, schools, hospitals, community centers, and cultural institutions. If your building qualifies, the city covers the full cost of materials and labor. For private buildings that don't meet the free criteria, there's a low-cost option where you pay a reduced rate for materials, but the labor and technical help are still free.
Since its launch, over 344 participants have gone through the program, according to The HOPE Program. The initiative also trains local workers in sustainable construction, giving New Yorkers paid experience in a growing green sector.
Technical requirements for your roof
Not every roof is eligible. The surface must be flat and in good condition, with minimal cracks. A parapet at least 3 feet 8 inches tall is required for worker safety. The roof base should be granulated sheets, asphalt, modified bitumen, or standard bitumen. Direct and safe access to the roof is essential—if there's hazardous machinery or a complicated hatchway, the building may be ruled out.
City inspectors will evaluate each property to make sure it meets safety standards. The goal is to coat 1 million square feet of rooftop every year, which would significantly cut greenhouse gas emissions.
How to apply
Ready to get your roof coated? Here's how to start:
- Email the program at [email protected] to kick off the technical evaluation.
- Call NYC 311 or the direct line 212-639-9675 for information.
- Nonprofits need to provide proof of their legal status.
- Affordable housing managers should coordinate an inspection visit.
- Community centers and schools can also join environmental awareness workshops.
This initiative is part of the city's broader push to meet carbon neutrality goals by 2050. Every 2,500 square feet of coated roof prevents roughly one ton of CO₂ emissions. It's a practical step that also addresses the urban heat island effect, which hits Latino and immigrant neighborhoods especially hard during heatwaves.

The cool roofs program is a win-win: it cools buildings, cuts energy bills, and creates green jobs. If your building qualifies, don't wait—apply now and make your summer a little more bearable.
