WELCOME TO GREEN ROOFS
Last spring, the New York City Council passed an ambitious climate legislation package focused on buildings, which are responsible for almost three-quarters of all local emissions.
GRRA members Dustin R. Partridge and Danielle Spiegel-Feld sit down with Urban Omnibus to clarify what New York’s new climate laws can mean for city residents, building owners, and birds.

Kingsland Wildflowers is a multi-level green roof that was constructed on top of the headquarters of New York City’s largest film production studio, located in the industrial area of Greenpoint, along Newtown Creek. and are the only natural habitat and green corridor for bird and wildlife populations.
Green Roof Common Questions
What is a green roof?
Where are green roofs located in NYC?
As of 2016, there were 60 acres of green roofs in all five boroughs of NYC. Green roofs are found on residential, commercial, city, state, and institutional buildings, including universities and major facilities like the Jacob K. Javits Convention Center. While this may sound like a lot, green roofs account for less than a tenth of a percent of the city’s roughly one million rooftops, which add up to about 40,000 acres of underutilized space.
Are green roofs important to urban environments?
How much does a green roof cost and are there financing options?
Before installing a green roof, consider the initial construction investment, maintenance cost, return on investment, and financing options including grants and tax incentives provided by NYC and other entities.
Can I design and install a green roof myself?
When designing a green roof, it is important to consider the environment, intent, and building requirements. The information below can help you get started, but it is not intended to be a comprehensive design guide. It is strongly advised to hire a professional design-build consultant to guide you through the design process, assist with procuring funding and permits, and safely install and maintain your green roof.
Benefits of Green Roofs
Improves Air Quality
Green roof technology can cut carbon and reduce air pollutants such as nitrous oxide, sulfur dioxide, and ozone. In addition, green roofs remove harmful fine particulate matter in the surrounding air.
Extends Roof Longevity
By protecting roof structures from weathering and degradation, green roofs decrease the cost of repairs and maintenance. Green roofs last up to twice as long as conventional roofs.
Increases Property Value & Decreases Tennant Turnover
Residential and commercial properties with green roofs have higher property values, lower tenant turnover, and lower energy costs. These advantages mitigate the initial high cost of green roof installation.
Increases Energy Efficienciency
Because of their insulating effect, green roofs can increase energy efficiency by reducing energy costs year-round and prolong the life of heating, ventilation, and HVAC systems. Calculate green roof energy savings here and learn how to make your building more energy-efficient.
By providing outdoor space where people can socialize, garden, play, and relax, green roofs, like parks, may improve overall health and well-being. Green roofs are an important source of green space in dense cities. In addition, research has found that office workers are 2.9% more productive when the view out of their office windows includes vegetation.
Lowers Urban Temperatures
Green roofs can insulate buildings, making them cooler in summer and warmer in winter. An increase of green area decreases ambient air temperature and helps mitigate the urban heat island effect.
Green roofs can retain more than half of annual precipitation, with performance dependent on the local microclimate, precipitation characteristics, growing media depth, and vegetation type. Stormwater retained by green roofs reduces the volume of runoff discharged to separate or combined sewer systems, helping to keep our waterways clean.
Reduces Noise &
Green roofs can reduce internal and external sounds by nearly 40 decibels. The soil substrate and plants absorb sound, unlike a conventional roof that simply reflects it.
Pollinator Week is an annual event celebrated internationally in support of pollinator health. It's a time to celebrate pollinators and spread the word about what we can do to protect them.
Popular events include planting for pollinators, hosting socially distant garden tours, participating in online bee and butterfly ID workshops!
