In New York City, there are new buildings going up every day. Two new local laws have been passed that require all newly constructed buildings and buildings replacing their roof to have a sustainable roofing zone that covers the entire roof surface. This roofing zone is defined as a green roof system that has a solar photovoltaic electricity-generating system. If a building is just replacing a part of the roof, it will be exempt from the laws. If there is a concrete roof deck, the building most likely will not have to replace it and therefore the laws do not apply.
There have been mixed thoughts on these new laws. However, over the course of time, these new roofs will improve the quality of life for everyone in NYC. The green roof must meet certain requirements such as the type of growth medium, depth, required drainage and types of plants that are acceptable. However, there are many green roofs and the details are a little unclear.
There are price levels for each type of green roof. The cheapest system is an extensive green roof, which has shallow layers of growing medium and small plants that do not irrigation. Most green roofs should have irrigation systems in order to fully establish plant growth. The most expensive option is called an intensive green roof. It has the deepest growing medium and the widest variety of plants. Keep in mind that there are many kinds of roofs between extensive and intensive and which roof you decide is best is determined by what the building wants for its roof. Do they want to insulate the building and conserve energy? Do they want to reduce storm-water runoff? Do they want to create a habitat for birds and butterflies? There are a ton of options and your building can decide what works best for it.
Right now, the laws are a little murky but the Department of Buildings says that clarification is coming. DOB said more details will come and that it will take enforcement actions by issuing violations if there are complaints about maintenance issues.
