Green roof cost will depend on the type of roof and the amount of weight associated with the type of system designed. A new building can be designed to support this additional weight. For existing buildings, a structural engineer should be consulted to ensure the rooftop is able to support the additional load. In many cases, the lightweight materials used for green roof construction allow for a retrofit on an existing building.
The Developers Green Infrastructure Guide 2.0 breaks down New Jersey’s Stormwater Rule amendments and helps developers and decision-makers understand more clearly green infrastructure options and advantages, compare alternatives, evaluate costs and benefits.
The Developers Green Infrastructure Guide 2.0 is brought to you by the Developers Green Infrastructure Task Force, a partnership between New Jersey Future and the New Jersey Builders Association.
The Task Force gratefully acknowledges the financial support of the William Penn Foundation, which made this project possible.
