Thinking of Developing a Green Roof?
The most cost-effective time to construct a green roof is during new construction or when the roof needs to be replaced. Constructing a green roof as part of a new construction or redevelopment project can help you comply with Philadelphia's stormwater management regulations. To read more about these regulations, visit Philadelphia Water's Plan Review website.
Before initiating a roof retrofit, you will need to determine the capacity of your building to sustain a green roof by hiring a licensed professional, such as a structural engineer or architect, to examine the existing roof structure. You will also need to acquire a building permit through the Department of Licenses & Inspections.
