Green Roof Materials and Technologies

Roof Assembly

 American Hydrotech’s Garden Roof Assembly allows the design professional to transform virtually any flat or sloped roof into a landscaped environment. Designed as a lightweight, low-profile system, the Garden Roof Assembly can be safely installed on roof and plaza decks not engineered to handle the heavy load requirements of a traditional green roof. And because the assembly incorporates Hydrotech’s Monolithic Membrane 6125, a proven roofing/waterproofing membrane, the building owner can be assured of a water-tight structure. The Extensive Garden Roof is ideally suited for locations that will receive little or no maintenance, or where structural capabilities are a concern. The soil mixture, composed primarily of mineral materials mixed with organic medium, can be very shallow (as little as 3 inches). The entire system is very light, weighing little more than a traditional ballast roof, allowing for safe installation on almost any existing roof. Sloped applications can now be accommodated with Hydrotech’s Garden Roof Assembly. Design professionals can now expand beyond traditional flat roof applications. In addition, a sloped Garden Roof Assembly can be designed for visibility and viewing from a wider range of locations, not just standing on the roof. Slopes ranging from 2:12 up to 12:12 are possible for extensive and limited intensive applications, provided the appropriate measures are taken to cope with the shear forces and soil retention. The Shallow-Intensive (Lawn) Garden Roof is still considered a lightweight assembly, but with a slightly deeper soil depth, and designed to support sod lawns and perennials. The Intensive Garden Roof incorporates plants that require regular maintenance, such as watering, fertilizing and mowing. The variety of plants possible is numerous, including sod grass lawns, perennial and annual flowers, shrubs, and even small trees. For more information, visit
