Green roofs have gotten a bad reputation with developers. Yet we’re finding that on urban sites, the only way to meet storm water management requirements is through the use of a cistern, underground storm water storage or a green roof or blue roof.
Implementing a green roof addresses green roof by-law’s that are being brought into force in many municipalities. And in areas where there is no green roof by-law, municipal reviewers are often so excited to see a green roof that they may be more lenient on other requirements.
This article (page 17) demonstrates that developers can get a return on investment from the installation of a green roof. Residential units with access the green roof sold for 3X the value of the units without this access.
Green roofs are more than “just costs and requirements”. We can expect to see more green roofs as progressive developers continue understand the return on investment and incorporate them into the pro-forma phase of the development.
