Early in June, Stuyvesant Town Property Services (SPS) announced that work had begun on a project aimed at cooling the complex’s buildings down in the summer — by painting the roofs.

Dubbed “Cool Roofs,” the initiative is part of a city program that debuted in 2009. For Stuy Town’s buildings, the city is footing the bill for the painting of the building roofs in white, reflective paint. (So tenants do not have to worry about a looming major capital improvement rent increase.)

An email sent to residents on June 8 said the work began that day with all of Stuy Town’s and Peter Cooper Village’s roofs to be included.

As the email from SPS notes, “during a typical summer day, flat, black asphalt rooftops can reach temperatures of 190°F. A roof treated with a specialized white coating can reduce internal building temperatures by up to 30 percent due to the sun’s rays reflecting off the roof instead of being absorbed. As an added benefit, this lessens the power needed to run A/C units resulting in less greenhouse gas emissions. Every 2,500 square feet of roof coated with the reflective paint can reduce the city’s carbon footprint by 1 ton of CO2. The program aims to coat 1 million square feet of rooftop annually.”
