Green roof systems provide many benefits, but with their exposed position and their shallow root zone, it is vital that they are irrigated.

Access have been supplying green roof solutions for over 20 years, and have considerable expertise in the design and supply of green roof watering systems. Access can provide advice to architects and contractors on the design and installation of systems.

Sedum type roofs often only need to be watered during very dry weather, which is beyond the capabilites of most irrigation controllers. To solve this problem, Access have developed the 'DroughtGuard' controller, which is designed only to water when there has been a prolonged period without rainfall.
