Greentop provides design services separately or integrated into a project’s total cost.


The most important aspect of creating a green roof is to design for the customer’s needs. Carefully listening to understand your wants and needs gives us the information we need to design a roof that is appropriate for your building and budget.          

If the primary goal is stormwater management, and the roof is in area that will rarely be seen, we won’t spend much time on elaborate aesthetics, but will concentrate on the best plants and soil composition to meet that goal. On the other hand, if the green roof will be enjoyed by people often, we want it to be beautiful, calming and inspiring. In addition to the performance of the plants and soil, we design for color, texture, topography, and seasonal flows.

We often work with architects to produce the best designs for our clients. Architects appreciate our ability to help fill information gaps and our experience help their designs succeed. We believe firmly in the value of teamwork to achieve excellent results for our clients.

At Greentop we do have a preference for plant in place installations. Plant in place offers a large degree of design and material flexibility and can be started with seeds, cuttings, plugs or mats. Most often we use a combination of these methods to create a beautiful end result. Greentop wants to give clients the best bang for their buck, and plant in place usually gives us the best opportunity to do that.

That said, we don’t let our preference for plant in place blind us to what the client wants and to conditions which might require a different type of system. Conditions and methods change, especially in a young industry like green roofs, at Greentop we use proven methods and are always open to improvements based on current research and trends. Our constant research provides us with up to date and effective solutions.
