Can I plant ivy on the roof?

If it is a commercial house with property management, it is generally not allowed to plant Parthenocissus tricuspidata on the top platform, because this will not only cause some damage to the external wall of the house, but also have a great impact on the facade of the whole building.

Now most people have bought houses, which belong to private property. If it is an old-fashioned house (6-8 floors) in the past, the external wall blocks are aging or cracked. If you plant Parthenocissus tricuspidata on the roof, Parthenocissus tricuspidata will definitely "take advantage of the situation" and take root in it, which will further destroy the external wall blocks and increase the insecurity of the house. In my opinion, it is advisable not to plant. But if it is a bungalow or a two-story house, all kinds of shading might as well.
