Green Roof Loading

Load limits on the roof of a building.

Green roof loading.

Saturated with water the weight can increase by as much as 35 to around 100 to 110 pounds per cubic foot. Extensive green roofs are designed to reap the benefit that green roofs offer at minimal cost and with very little maintenance. In order to stay intact and in place a roof must be able to resist loads both permanent and temporary that are pushing. In older buildings or new build this may require costly structural reinforcement which in some cases may prove prohibitively expensive.

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. 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. Extensive modular green roofs. Here s a summary of the different types of green roof available.

What is the impact of green roof weight on building structure. Types of green roofs. One cubic foot of dry agricultural dirt or loam typically used for a green roof weighs between 75 and 81 pounds. 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.

Container gardens on roofs where plants are maintained in pots are not generally considered to be true green roofs although.
