The plants that are selected for a garden roof vary by region, but they generally consist of plants that are well suited to extremes in temperature and exposure, and are often low growing. Broadly speaking: things that grow on cliffs are good for garden (sometimes known as vegetated) roofs.
At the same time, the potential benefits of a garden roof are fairly well established: reduced stormwater runoff, improved energy performance, and reduced urban heat island effect. But what you don’t often hear about is how beautiful a garden roof can be. In fact, if you’ve ever had the chance to tour one, you know it’s quite an experience. It’s a little bit like being on a mountaintop, and with the birds chirping and greenery all around you, it can be very beautiful.
Although garden roofing is a small segment of the marketplace, for these reasons and many more, it continues to show strong growth. That’s why we’re so excited to be partnering with proven vegetative roof provider LiveRoof®. Our partnership gives designers and facility managers a single point of contact for the project, and the system is installed in modules or trays, which eliminates the need for a drainage mat, filter fabric, or drainage layer like conventional garden roof systems.
The system offers a variety of plant options and system depths. (In vegetated roofing parlance, lower system depths are known as extensive — think of spreading the soil out extensively — and thicker ones are known as “intensive.”) Whatever your needs, the LiveRoof® system offers the pre-vegetation of carpet or sod-like green roof systems but with a broader plant palette and without the need for additional watering and maintenance required by mat systems for establishment.
With tightening stormwater regulations and increasing sewer connection costs in many cities, garden roofing is making more and more financial sense, not to mention the aesthetic and marketing benefits. Let us know if we can be of assistance with your project.
