Green Roof Weight Load

Mid range 5 inch systems weigh approximately 34 pounds per square foot and are compatible with wood or steel decks.

Green roof weight load.

Heavier intensive green roofs generally require a concrete supporting deck. 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. For more in depth information the astm standards e2397 and e2399 has published specific protocols for determining the weight and dead load of green.

What is the impact of green roof weight on building structure. 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. In older buildings or new build this may require costly structural reinforcement which in some cases may prove prohibitively expensive. One important item to design for is an increased structural load.

This is especially true of intensive green roofs which can have soil that is two feet deep or more. 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. 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.
