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 – we’d concentrate on choosing the best plants and soil composition to efficiently capture stormwater and prevent runoff. 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.

There are many green roof systems available, each with its pros and cons. Greentop is experienced and proficient in all systems, from planting in-place plugs and cuttings, to installing sedum mats and pre-grown trays. We can help you choose the right system to meet your objectives.
