There will be some shortcomings on the roof.
1, which will exceed the building payload.
Growing vegetables on roofs or roofs often requires soil on them. When the soil thickness reaches 15 cm, besides the weight of various tools and personnel, it will also exceed the upper limit of the load that the building can bear. Generally speaking, the effective load of the roof of a building is 1.50kg per square meter, so the harm of growing vegetables on the roof is quite great.
2, causing water leakage.
If the roof and roof waterproof measures are not good, planting vegetables on the roof and roof will often lead to roof and roof leakage.
3. Block the sewer.
Growing vegetables on roofs and roofs often leads to some dead branches and leaves. These dead branches and leaves, accompanied by soil, often block sewers. When watering or raining, the water will not be discharged or discharged uncleanly, resulting in water accumulation on the roof, which will also cause water leakage for a long time.
