A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium planted over a waterproofing membrane it may also include additional layers such as a root barrier and drainage and irrigation systems.

Green roof loading.

In older buildings or new build this may require costly structural reinforcement which in some cases may prove prohibitively expensive. Load limits on the roof of a building. Types of green roofs. Container gardens on roofs where plants are maintained in pots are not generally considered to be true green roofs although.

The second trussed roof is designed for a dead load of 160kg m 2 and a live load of 40kg m 2. A traditional green roof can exert a load of up to 250 kg per m2 and that inevitably means a strong building is required to support the weight. The venny green roof has shallow substrates on two types of roof the first roof is on shipping containers and is designed for a dead load of 250kg m 2 and live load of 100kg m 2. Structural loads weight of green rooftops.

What is the impact of green roof weight on building structure. Saturated with water the weight can increase by as much as 35 to around 100 to 110 pounds per cubic foot. Extensive modular green roofs. Roofs are under a lot of pressure.

Extensive green roofs are designed to reap the benefit that green roofs offer at minimal cost and with very little maintenance.
