Green Roof Weight Load

The simple answer is that the weight of a green roof is determined by the strength of your build or structure so there are a few things to consider when creating your own green roof.

Green roof weight load.

This is especially true of intensive green roofs which can have soil that is two feet deep or more. There are a number of things to consider when designing for a green roof. 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.

What is the impact of green roof weight on building structure. Heavier intensive green roofs generally require a concrete supporting deck. A green roof or living roof is a roof of a building that is covered with plants often wildflowers or grass and a growing medium planted. Mid range 5 inch systems weigh approximately 34 pounds per square foot and are compatible with wood or steel decks.

What is a green roof. 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. For more in depth information the astm standards e2397 and e2399 has published specific protocols for determining the weight and dead load of green.
