Chicago and the Chicagoland Roofing Council Professional Roofing Contractor has been at the forefront of this movement and is best qualified to install these complicated assemblies because. That’s because they understand how to treat the critical element - the roof.

There are two types of garden vegetative roofs. The vegetative media and plants can be supplied in trays or “built-in-place”. The trays have plants in them that are grown offsite, but are indigenous to the area. The “built-in-place” system components are custom installed from the roof membrane up. Drainage and water retention boards are installed over the roof membrane and insulation. A filter fabric is installed either on the water retention board or separately. Then, the soil media is placed over the insulation at specified thicknesses. Plants are inserted into the media by hand.

Since a garden roof absorbs less heat from the sun than a dark colored roof, the building it protects also stays cool, requiring less energy for air conditioning.

Garden roofs also help with storm water management and water quality. They reduce and slow storm water runoff (until saturated) and filter out some pollutants contained in rain water.
